electrical charge C There are 9 amino acids that are the building blocks of protein Ill What makes protein different from one another 0 The sequence determined by genes 0 The shape determines the function and shape is determined by which amino acids are where o The electrical charge positive negative neutral IV Denaturation the irreversible change in a protein s folded shape brought about by heat acids bases alcohol salts by heavy medals or other agents begins the process of digesting foods and can also destroy body proteins HNF150 SPRING 2014 Prof Alaimo Lecture Notes V Protein Synthesis

the diet needed to make proteins B Conditionally Essential Amino Acids amino acid that is normally nonessential but must be supplied by the diet in special circumstance when the need for it exceeds the body s ability to produce VII Digestion In the stomach strong acid produced by the stomach uncoils protein s strands 0 Proteins activated by acid digest proteins from food denatured by acid 0 Digestion and absorption of other nutrients like iron depend on how strong the stomach s acid is o Stomach lining has a little protein in it and mucus for protection 0 In the small intestine proteins are denatured and into smaller pieces 0 Most are still polypeptides large strands of protein 0 Alkaline juice from the pancreas neutralizes the acid from the stomach 0 pH is 7 o Dipeptides protein fragments that are two amino acids long 0 Tripeptides protein fragments that are three amino acids long 0 After they are broken down into single amino acids and then absorbed by cells and into bloodstream VIII Adverse Effects of Amino Acid lmbalances Food allergies IX Functions of Proteins A Supporting growth and maintenance need to make new proteins when growing if we cut ourselves we will need new protein hair nails B Building enzymes hormones and other compounds Catalyst substance the speeds up the rate of a chemical reaction without itself being altered in the process Enzymes speeds
