Document Summary
Amino group, acid group, and a distinctive side chain. Mighty 20: essential amino acids obtained from diet vs. nonessential amino acids. Essential amino acids: cannot be made by body and must be obtained from diet. Nonessential amino acids: body is able to make from cho. Conditionally essential: when non-essential amino acids become essential. Peptide bond: connects one amino acid to another. Order of amino acid in a protein determine the protein"s overall shape. Alteration of protein structure, which changes the structure and function of protein. Protein turnover: process of continuous breakdown and synthesis of protein from it"s amino acids. Digested and absorbed in the small intestine: polypeptides are broken down into tripeptides, dipeptides, and amino acids. Instructions for protein synthesis located in dna (cell nucleus) Gene: dna segment that codes for a specific protein. Sickle cell anemia: inherited abnormal hemoglobin that causes distorted blood cells. Provides structural and mechanical support and help maintain body tissues.
