Fat is often maligned in the media, and is often named “public enemy #1” because of the obesity epidemic that our country has been struggling against for several years. However, fat is an essential component in the human body. Fat must be taken in and used by the body to maintain health. That said, moderation is key. Too much of a good thing, can lead to other health issues, as seen by the obesity level in this country. It is important to strike a balance between healthy consumption of fats that the body needs to function, and the other end of the spectrum, too much fat or no fat at all in the diet. Below is a brief overview of how the body uses fats, known as lipids, in the body and why lipids are essential to the body’s health.
A. Energy Stored as Fat
Food is often shared with others socially and enjoyed for its taste and aroma.
Fatty foods are often considered pleasurable to eat because they provide people with richness of flavor, texture and an overall feeling of satisfaction. However, fat in foods is not just there for pleasure. The body uses fat an energy source. The fat is stored in tissue called “adipose tissue.” A special type of molecule, called a triglyceride, is used by the body to store fat. Triglycerides are used as large, fat storage energy units (Wolfe, 2014).
Triglycerides consist of three fatty acids and one glycerol molecule. To turn this fat storage into energy a triglyceride is broken down into smaller molecules through a catabolic process. Through the process of glycolysis, triglyceride molecules are broken down by glyceraldahyde-3 phosphate into three free fatty

acids and one glycerol molecule (Wolfe,…...

...Biochemical Implications in Metabolic Disorders Kim Wertz Western Governors University Biochemistry 208.5.4-01-208.5.5-07 WGU August 7, 2013 Biochemical Implications in Metabolic Disorders Enzymes play an important role and are involved in the process of fructose breakdown. The enzymes are catalysts, meaning, they work to lower activation energy without using the reaction. Sucrose is plain table sugar and it is broken down into glucose and fructose that needs to be broken apart. This process known as glycolysis will break down glucose-producing pyruvate and then it goes into the citric acid cycle to produce ATP. Fructose will break down first, forming fructose 1-phosphate by the enzyme, fructokinase. Aldolase B then will convert the fructose 1-phosphate into DHAP and glyceraldehyde as they enter into the glycolysis pathway. When there is a deficit or a mutation of Aldolase B gene, then hereditary fructose intolerance will occur. Individuals are usually asymptomatic until they ingest sucrose, fructose or sorbitol. When the fructose is ingested, there is a block of the Aldolase B, which will cause an increase of the F1P. This is an autosomal recessive condition from mutation of the Aldolase gene. As of 1991, there have been eight structural defects found in the Aldolase B gene, as documented by Wikipedia. Mutant alleles result in many different mutations; one being base pair substitutes, small deletions, and areas of the splicing regions......

...1. Lipids to ATP * Hydrolysis is the first step in the breakdown of lipids. This happens in the cytoplasm, to produce fatty acids and glycerol. The glycerol is then metabolized into dihydroxyacetone phosphate. This hydroxyacetone is further metabolized into one of two compounds: pyruvic acid (for energy) or glucose-6-phosphate (during gluconeogenesis). * Fatty acids are catabolized into Acetyl Coenzyme-A, during something called the fatty acid spiral, which is then transformed into ATP, carbon dioxide, and water using the electron transport chain and the citric acid cycle. * ATP is created from both the citric acid cycle and the fatty acid spiral (Brandt, n.d.). 2.  Saturated vs Unsaturated fatty acids  * Saturated fatty acids: carbons are single bonded, solid at room temperature * Unsaturated fatty acids: carbons are double bonded, liquid at room temperature (Fatty Acid, 2015) 1.  Saturated Fatty Acid 2.  Unsaturated Fatty Acid 3. 4.  No-Fat Diets * Non-fat diets are detrimental to the body, because vitamin-D, an essential vitamin, cannot be absorbed without lipids (fats). Vitamin D is essential to the absorption of vitamin C and phosphate. Vitamin C and phosphate are necessary for bone structure, neuromuscular function, and immune function. * Lipids are also necessary for the absorption of estrogen, one of the hormones responsible for reproduction, related to fetal growth and uterine changes during pregnancy.

...Enzymology and Catalytic Mechanisms GRT3 Enzymes are proteins that speed up chemical reactions. They are catalyst. Without catalyst, chemical reactions would still take place, but at a slower rate and the body wouldn’t benefit. All enzymes possess two essential properties. First, enzymes accelerate the rate of chemical reactions without being consumed and/or changed by the reaction. Second, enzymes accelerate reaction rates without changing the chemical equilibrium among reactants and products. Each enzyme has a receptor site, and they are very specific to which molecule (substrate) it will interact with. When a substrate is captured, it will either be combined to create a product or it will be broke down. Fructose is primarily metabolized in the liver. Fructose alone cannot be used as energy. It has to be broke down for use. Enzymes in the liver aid fructose metabolism. Fructose binds to the receptor site on the enzyme fructokinase. This enzyme uses ATP and ADP cycle (energy) to speed up the chemical reaction to convert fructose into Fru-1-p. Next, Fru-1-p will undergo the next reaction and will produce either DHAP or glyceraldehyde by way of the enzyme Aldolase B. (Wikipedia, 2015) As stated above, Aldolase B is active specific to the substrate Fructose-1-Phosphate. Fructose-1-phos is derived from fructose. It’s produced by fructokinase which is available in the liver. It’s converted by aldolase B into dihydroxyacetone phosphate and glyceraldehyde. A......

...A. Explain how lipids, in the form of triglycerides, are broken down to produce ATP, including ​each​ of the following: Triglycerides are first broken down to fatty acids and glycerol by separating the bond between the glycerol and the fatty acid. The fatty acids undergo beta oxidation and are broken into two carbon units. The carbon subunits generate Acetyl­CoA. (O’Malley 2014) During beta oxidation hydrogen and electrons are removed from the fatty acids and are carried by NADH and FADH2 to the electron transport chain to generate ATP. Acetyl­CoA enters the citric acid cycle which removes electrons and hydrogen. NADH and FADH2 is used to carry the ions to the electron transport chain to form ATP. B. Explain two differences between saturated and unsaturated ​fatty acids​ (not fats). A saturated fatty acids has hydrogen on all points of its chemical chain. Unsaturated fatty acids will have a pair of hydrogen missing on its chain. Saturated fats are solid at room temperature vs liquid for unsaturated. 1.

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.

...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......

The four forces that stabilize a protein. * Hydrophobic interactions which are interactions by nonpolar amino acids. The weakest of the four types of bonds. * Hydrogen bond made up of interactions of polar or charged amino acids. The amino acids share their hydrogen. This is also a weak bond, but it is stronger than the hydrophobic interaction. * Ionic bonds are made up of charged amino acids. A positive charge of an amino acid attracts to a negative charge of another amino acid. This bond is a little stronger than the hydrogen bond, but not as strong as the polypeptide bond. * Disulfide bond only occurs between two cysteine amino acids. Two cysteine amino acids form a sulfa-sulfa bridge. This is a strong covalent interaction.

...A. 1. Oxygentated blood has picked up oxygen from the lungs. Deoxygenated blood has had most of its oxygen removed and needs to return to the lungs for re-oxygenation. Oxygenated blood is bright red. Deoxygenated blood is dark red. Oxygenated blood cells have a relaxed shape whereas deoxygenated blood cells have a tense shape. 2. Carbon dioxide concentration decreases as blood nears the lungs, which in return causes and increase in pH . Increased pH causes increased affinity for oxygen which causes the hemoglobin to pick up oxygen entering your blood to be transported to the body’s tissue. Hemoglobin loses hydrogen ions from specific amino acids at key sites as pH rises causing slight changes in its structure that increase its ability to bind oxygen. As pH falls hemoglobin picks up hydrogen ions and its affinity for oxygen decreases. Increasing carbon dioxide concentration in your tissues cause a decrease in pH, which in turn forces hemoglobin to dump the oxygen it's carrying so your cells can use it for energy . a. 3.

...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......
