Document Summary
All the proteins in the body are made from the 20 amino acids coded for by our dna. The unique sequence of amino acids in each protein predicts its conformation. The properties of side chains on each amino acid dictates the associations between them, leading to the conformation of the protein. All of the 20 amino acids have a common structure. The alpha carbon is substituted with an amino group, a. Carbolylic acid group, a hydrogen and an individual side chain (r) The chemical properties of the side chains of its amino acids determine how the molecule can interact with other molecules. At physiological ph, amino and carboxylic acid groups are charged. At this ph, the molecule is neutral. Depending on the pka of each side chain, the group may be charged or uncharged at physiological ph (7. 35-7. 45 in blood)
