Protein and Amino Acid Supplementation in Sports The popularity of increasing the “performance-enhancing” supplements‚ Protein and amino acids‚ has flourished among all athletes. This increase is attributed to the belief by many of the athletes that it provides endurance‚ strength and speed enhancement. Amino Acids (AA) enhanced physical feats‚ improved energy and recovery sooner from fatigue. The three vital Amino Acids which were given a high focal point among athletes are leucine‚ isoleucine

October 2‚ 2012 Biochemistry I Circular Dichroism and Secondary Structure of Proteins Proteins are vital to an organism life; they are involved in nearly all cellular functions. It is an essential part of enzymes‚ the cellular membrane‚ active transport‚ protein synthesis and wound healing. Because one relies so heavily upon proteins and its function the structure of proteins is also very important. “The way a protein will fold over its self-determines how it interacts with other chemicals in its

glucose cycle. It forms an energy reserve that can be quickly mobilized to meet a sudden need for glucose‚ but this is less compact. Muscle glycogen is converted into glucose by muscle cells. On the other hand‚ liver glycogen converts to glucose for use throughout the body. The liver is essential for monitoring and maintaining a relatively constant level of glucose in the bloodstream‚ hence the liver is involved in glycogen breakdown and synthesis because these pathways allow the liver to remove

THE ROLE OF PROTEIN MISFOLDING AND AGGREGATION IN BSE When a protein misfolds it changes its behavior and function. If it becomes hydrophobic after once being polar. The properties and functionality of the protein are no longer useful to the organism and disaster results. PrPSc is hydrophobic‚ it avoids water inside of the cell…it attracts and attaches other proteins to misfolds and become hydrophobic …Misfolding spreads because the PrPSc act as chaperone proteins to convert PrPc TO PrPSc and

Assessment of Catalase Function Lab Introduction The purpose of this lab report was to test and measure the rate of substrate destruction by an enzyme‚ we tested the destruction of hydrogen peroxide by the enzyme catalase. Hydrogen peroxide is a poisonous by product of metabolism that can damage cells if it is not removed. Catalase is an enzyme that speeds up the breakdown of hydrogen peroxide into water and oxygen gas. H2O2 + catalase → H2O + O2 A catalyst is a substance that lowers the

How Primary Structure Determines Protein Function Proteins are everywhere. As enzymes‚ they catalyse chemical reactions. There are many different types of proteins: carrier and channel proteins which transport substances‚ receptor proteins which are recognition site for antibodies and hormones‚ structural proteins which support cells and tissues‚ and hormones which transmit information. Proteins are big molecules with large molecular masses that are made up of many amino acids; they’re‚ essentially

is that RNA uses uracil instead of the thymine in DNA. DNA replicates itself and RNA is synthesized from RNA on an as-needed basis. Their stability and reaction is also different. DNA is more stable and less reactive than RNA because of the deoxyribose sugar’s C-H bonds. It is stable in alkaline conditions; DNA has smaller grooves‚ which makes it harder for enzymes to “attack.” RNA is more reactive because of the ribose sugar’s C-OH‚ hydroxyl‚ bonds. Unlike DNA‚ it is not stable in alkaline conditions
