will be testing some food products for sugar‚ starch‚ protein‚ and lipids. We will be testing each food product with Benedict’s‚ Lugol’s‚ Ninhydrin‚ and Albumin solutions. If when we test each substance and the color changes‚ then that product has one or some of sugar‚ starch‚ protein‚ or lipids in it. Methods: As suggested in the book on page 36. Or otherwise instructed! Results: Food Product | Sugar | Starch | Protein | Lipid | Color change | Knowns | Benedict’s | Lugol’s | Ninhydrin | Sudan

Biochemistry GRT1 Lipids are molecules that are not soluble in water but can be dissolved in non-polar substances such as alcohol or chloroform (Mandal‚ n.d.). Lipid molecules are stored in adipose‚ or fat tissue‚ and can be broken down in our bodies to form an energy called ATP. To do so‚ the lipid molecule is dissected into its base pieces‚ glycerol and fatty acids. Each of the fatty acids is then broken down into two-carbon pieces and acetyl CoA is formed from each carbon

Metabolism Figure 1 above is adapted from João M‚ et al (2012) the chromatographic methodologies for analysis of cocaine and its metabolites which‚ shows the metabolic pathway of cocaine administrated. Cocaine is largely metabolized into two major metabolites benzoylecgonine (BE) and ecgonine methyl ester (EME) and two minor metabolites norcocaine (NCOC) and m- and p-hydroxycocaine (OH-COC) (Goldstein et al.‚ 2009). Benzoylecgonine is primarily produce in the liver by human carbozylerstrase type

------------------------------------------------- Lipid Structures of some common lipids. At the top are cholesterol[1] and oleic acid.[2] The middle structure is a triglyceride composed of oleoyl‚ stearoyl‚ and palmitoyl chains attached to a glycerol backbone. At the bottom is the common phospholipid‚ phosphatidylcholine.[3] Lipids constitute a broad group of naturally occurring molecules that include fats‚ waxes‚ sterols‚ fat-solublevitamins (such as vitamins A‚ D‚ E‚ and K)‚ monoglycerides

Lipid Panels Case Study Subject #1 This fifty year old man that has no apparent health problems has a low ‘HDL’ of 30mg/dl. That’s not a good thing because he’ll be more likely to develop heart disease or have a heart attack/stroke. Anything over 60mg/dl is considered to be optimal. He is border line high for LDL’s of 160mg/dl‚ the ideal number is 100mg/dl or lower. That number tells me he is at greater risk to heart disease and/or heart attack. Better diet and exercise would help him tremendously

Lipid Digestion The process of mastication is our only conscious act in the digestion of the foods we consume. After that‚ it’s out of sight‚ out of mind; but should it be? What does it take to transform that last swallow into the energy our body needs to sustain itself? In the case of lipid digestion‚ the real magic occurs throughout the gastrointestinal tract with a synergistic collaboration from the accessory organs: the liver‚ gallbladder and pancreas. Understanding the whole process of digestion

AS Biology‚ Biological Molecules Revision Notes Distinguish between monomers and polymers: Monomers- Identical small molecules. Polymers- Chainlike molecules formed from the linking together of many similar. Distinguish between monosaccharides‚ disaccharides‚ and polysaccharides: Monosaccharides- Simple sugars; sugar molecules may be enantiomers due due to the spatial arrangement of parts around asymmetric carbons; raw material for synthesis of other organic molecules. Disaccharides-
