Document Summary
Protein: peptide bond: condensation (loss of water) of amine group of 1. Aa with the carboxyl group of another aa. Protein: can have 2 aa (dipeptide), 3 aa (tripeptide), about 50-100 aa (polypeptide) or over 100 aa (protein) Interactions of side chains causes folding and resultant 3d structure determines function. Functions of protein: structure, regulators of metabolism (functional proteins, energy (when you run out of cho and fat, it can be used; also with starvation you use up proteins and have a loss of function of respiratory muscles) Big box in the centre is very important: pool of aa in the blood and body fluids (think of this as one big pool even though it is two or three, but they are able to exchange components) Aa found in dietary protein becomes available to the body via digestion (protein gets broken down into aa and absorbed into the bloodstream)
