Document Summary
There are 20 different amino acids, each with its own side chain. 9 amino acids are essential and must come from the diet. 3 parts: amino group, acid group, side group. Normally sorted via polarity: non-polar amino acids, negatively charged (acidic) polar amino acids, positively charged (basic) amino acids, uncharged polar amino acids. Chains of linked amino acids: peptide bonds, polypeptides. Protein shape is determined by the sequence of amino acids along the chain. Changes to environment of a protein may cause it to break apart hydrogen bonds causing the protein to unfold. Unfolded protein is denatured and no longer functional. Change in temperature or ph can cause proteins to denature: in food: changes the texture and consistency (better, in the body: no longer functional. Denaturing muscle protein is an important part of cooking: muscle is made of protein, collagen is a protein, muscle fibers are arranged in bundles held together by collagen.
