The four forces that stabilize a protein’s structure at the tertiary level are as followed:
Hydrophobic is the interaction between nonpolar amino acids (Borges, 2014). These amino acids are not capable of hydrogen bonding, however their hydrocarbon regions interact closely by pulling together tightly tucking away from the exterior of the cell (Borges, 2014). This is the weakest of bonds (Borges, 2014). Next, Hydrogen bonds are polar or charged amino acids
(Borges, 2014). This is where one amino acid is sharing its hydrogen atom with another oxygen atom (Borges, 2014). This is a stronger bond than hydrophobic interaction but still weak
(Borges, 2014). The third bond is called Ionic Bond. This is when you have charged amino acids, opposites attracting one another (Borges, 2014). Ionic bond is stronger than a hydrogen bond but not as strong as a polypeptide bond (Borges, 2014). The final bond is a Disulfide bond.
The disulfide bonds are only formed between two Cysteine amino acids that are brought together

...GRT task 2: Biochemistry (V. Undergrad-0814) Proteins are made up of smaller units called amino acids. Hundreds or thousands of amino acids in long chains form a protein molecule. There are 20 different types of amino acids that combine to make a protein. Amino acids are classified into three groups: essential amino acids, non-essential amino acids, and conditional amino acids. Essential amino acids cannot be made by the body and must come from food. Non-essential amino acids can be produced by the body even if not obtained through food ingested (Wolfe,2000). Conditional amino acids are needed at times of stress, like an illness. Proteins can be described as polar and non-polar depending on how they interact in the environment. Polar and non-polar chemical trait allows for the amino acid to direct themselves toward water (hydrophilic) or away from water (hydrophobic). Valine is an essential amino acid that enables chemical messages to be transmitted from the brain. Valine’s chemical structure is C5H11NO2 and is a branched chain amino acid. Valine is non-polar in nature so it is not a charged molecule. Valine is hydrophobic and if found deep inside the structure for this reason. Valine is important to muscle function as the muscle recovers from strenuous activity. The amino acids sequencing of a protein decides its structure and function. Protein function is also dependent on its structure but some changes can disrupt the structure. When a protein loses function......

...Biochemistry Task 5- Lipids Student ID# Western Governors University 05/21/2015 Biochemistry Task 5- Lipids A. Fat is stored in the body and used as an energy source when not enough energy is available from food. This process involves dismantling the stored fat in fat cells and releasing the components into the bloodstream. The major storage form of fats in our body are triglycerides, which are made up of three fatty acids bound to glycerol. Adipocytes are primary cells that store fat in the triglyceride form. White adipose cells are used to store energy (O’Malley, M. 2014). 1. Triglycerides are the storage molecules that are broken down and used to produce ATP. The triglycerides break down into two different items, glycerol and fatty acids. The triglycerides are formed when glycerol binds to three fatty acid molecules. The fatty acids each break down into 2 carbon parts. Each part of the carbon makes Acetyl CoA. The Acetyl CoA molecule then enters the Citric Acid Cycle before it moves on to the next step, the electron transport chain. The end result of each of these steps is the production of 12 ATP (Hudon-Miller, 2012). B. 1. Saturated fats do not contain a carbon-carbon double bond. Unsaturated fats contain at least on carbon-carbon double bond. The saturated fatty acid chains can stack while the unsaturated fatty acid chains are kinked by the double bond. 2. Saturated fats have a high melting point and are solid at room......

... Biochemistry Task 4 09/05/2015 1. Describe two important features that make all enzymes ​catalysts​. A catalyst is a substance which can accelerate the rate of a chemical reaction without going through a chemical change itself. Enzymes are proteins which help accelerate the rate of reactions. Enzymes also lower activation energy without being used. (Hudon­Miller 2012) After and enzyme and substrate bind it converts the substrate to it’s specific product. The enzyme remains unchanged and it is free to move on to other products as the enzyme itself does not undergo a chemical change during this process. 2. Create an original diagram, or series of diagrams, with clear labels, that demonstrates the entire enzymatic cycle described by the lock and key model OR the induced fit model. 3. Create an original diagram, or series of diagrams, with clear labels, that illustrates the activation energy of a reaction in the presence and absence of an enzyme. 4. Explain the reactions catalyzed by enzymes in the first two steps of fructose metabolism in the liver, including ​each​ of the following​: After consumption fructose is transported into the liver. Once in the liver the substrate fructose is catalyzed by fructokinase and substrate F­1­P is formed. This substrate binds with the enzyme Aldolase B creating the products DHAP and glyceraldehyde.

Biochemistry Task 5 Lipids

...Biochemistry Task 5 Lipids A. Adipose tissue stores fat in the body. The fat storage molecule is called a triglyceride. Triglycerides are composed of a glycerol attached to three fatty acids. In order to use a triglyceride for energy, the fatty acids are broken away from the glycerol. These fatty acids are considered free fatty acids. Free fatty acids are broken down, two carbons at a time by beta oxidation. Each two carbon unit becomes Acetyl CoA, which then enters the citric acid cycle. Also, during beta oxidation there are electrons and hydrogens that are removed from fatty acid. They are carried by NADH and FADH2 to the electron transport chain. They are used to form ATP from ADP and a phosphate. B. There are two types of fatty acids, saturated fatty acid and unsaturated fatty acid. Saturated fatty acids are saturated with hydrogen, meaning all the carbons in the chain are filled with hydrogen. Saturated fatty acid chains all look similar which makes it easy for them to build on one another. The force that holds them together is known as hydrophobic interactions. This allows fatty acids to be solid at room temperature. Saturated fatty acids are mainly from animal food sources. Unsaturated fatty acids will not be saturated with hydrogen, instead there is a double bond that lessens the amount of hydrogen in a chain. This double bond bends the tail and the structure becomes irregular. This irregularity doesn’t allow them to stack well, therefore unsaturated fatty......

Biochemistry Task 3

...Jessi Ayers 11-8-2015 Biochemistry Task #3 1. Explain two differences between the oxygenated and deoxygenated states of hemoglobin. One big difference would be that the oxygenated state of hemoglobin has oxygen binding to the heme portion of the molecule. Deoxygenated hemoglobin has released the oxygen to the tissues. Hemoglobin has two states; Taut and relaxed. Deoxygenated hemoglobin is in the “T” state and Oxygenated hemoglobin is in the “R” state. Deoxygenated hemoglobin has a low affinity for oxygen in its “T” state, while Oxygenated hemoglobin binds with greater affinity. 2. Explain how pH impacts the binding and release of oxygen by hemoglobin. The way pH acts and binds and releases oxygen is called the, “Bohr effect.” The ability of hemoglobin to bind to oxygen is related to CO2 concentration. CO2 concentration is also directly related to acidity; the more CO2, the higher the acidity, which also means a lower pH level (Low pH equals high acidity). When the CO2 concentration gets higher and the pH gets lower, it causes the hemoglobin to “get rid” of the oxygen. On the flip side, when there is less CO2 and the pH increases, this causes the hemoglobin to “pick up” the oxygen. This process is also known as the, “Hemoglobin Dissociation Curve.” 3. Explain how the diseased cells differ from normal red blood cells in their capacity to transport oxygen. Normal red blood cells contain hemoglobin that assist in transporting oxygen to the whole body, referred to......

Wgu Biochemistry Task 3

...WGU Biochemistry Task 3 A1) There are several differences between the oxygenated and deoxygenated states of hemoglobin. One difference can be seen in the conformational state of the hemoglobin protein. When oxygenated, the protein takes on the T (tense) state; and when deoxygenated, the protein takes on the R (relaxed) state (Hudon-Miller, 2012b). Another difference arises when oxygen binds to the hemoglobin, resulting in a change in the shape of the protein. In the deoxygenated state, the heme group forms a domed shape; and in the oxygenated state, the heme group takes on a planar shape (Hudon-Miller, 2012b). A2) The relationship between pH and the ability of hemoglobin to bind and release oxygen is referred to as the Bohr Effect. The blood’s pH level is greatly influenced by the carbon dioxide that is produced by most of the body’s cells during the citric cycle (Hudon-Miller, 2012d). Greater CO2 concentration lowers the blood’s pH level, making it more acidic. In turn, lower CO2 concentration increases the blood’s pH level, making it more basic. Since the lungs function involves breathing in oxygen and blowing out carbon dioxide, the lungs are absolutely crucial in maintaining the pH balance that the blood requires (Hudon-Miller, 2012d). While in the lungs, the hemoglobin becomes saturated with oxygen and slowly delivers it to the body’s tissues as it travels through the bloodstream. At the same time, the hemoglobin is also picking up the carbon dioxide that is......

Biochemistry Task 5

...Biochemistry Task 5 March 6, 2016 A. Triglycerides are the main make up of body fat in animals and humans as well as vegetable fat. Triglycerides are made up of glycerol and three fatty acids. Fats or lipids as a whole are not bad for you as they are used for energy, always in moderation, but there are different types of fats that you do need. Your body utilizes saturated fat very fast as opposed to other fats that has to go through different stages to be used. Triglycerides in food are digested and are processed in the liver combining it with a protein and then travel through your blood stream to your cells where they are then used for energy. Glycerol enters into the pathway through the Pyruvate and then onto Acetyl-CoA where it enters the Cori-cycle. From there it is transported to the electron transport chain where the end product is ATP. ATP is the body’s energy. Through beta oxidation fatty acids enters the pathway through the Acetyl-CoA. From here it moves the Cori cycle where they are then broken down into sugars and transported to the electron transport chain where ATP is the end product. Low fat diets are dangerous in that they strip the body of the process of this breakdown. Reduces energy stops the breakdown of fat for use in the digestive system gallbladder and liver. With this reduction the decrease of bile also stops the production of CCK or Cholecystokinin which signals the pancreas to release bile to breakdown the lipids. Simply the product will be...

...Task 4: Metabolism 1. They speed up reactions and do not change themselves, which means they can be used over and over. Enzymes help facilitate chemical reactions. Enzymes will lower the activation energy needed to start the reaction and that is how the reaction will be sped up. Enzymes are specific for certain reactions and are proteins. Not all catalysts though are enzymes. (Sanders, 2014) 2. (Gresham HS IB Biology, 2007) 3. (Hudon-Miller, S. 2012) 4 & 5. When table sugar is consumed, it is broken down into glucose and fructose. Glucose is used in the blood stream. Glucose can be stored in the liver as glycogen. Fructose does enter glycolysis, but first two steps are original to fructose. The first step involves breaking down fructose into fructose-1 phosphate by the enzyme, fructokinase. Fructose is the substrate of fructokinase and it’s product is fructose-1 phosphate. Fructose-1 phosphate is converted into DHAP and glyceraldehyde (products), by the enzyme aldolase B which will enter the glycolysis pathway. (Hudon-Miller, S. 2012) In HFI, there is an aldolase deficiency, so there is no conversion of fructose-1 phosphate into DHAP and glyceraldehyde, so they do not enter the glycolysis pathway to produce ATP or in gluconeogenesis. The fructose is still achieving phosphorylation by fructokinase, which results in a build up of fructose-1 phosphate. The liver cells are unable to utilze fructose as energy. There becomes an abundant buildup of......
