Protein composed of carbon, hydrogen, oxygen and nitrogen atoms, arranged into amino acids linked in chain. Amino acids building blocks of proteins - amino group, acid group, hydrogen atom & distinctive side group, all attached to central carbon atom (20 of them) Nonessential amino acids body can make them (aka dispensable) Essential amino acids required by body but can"t make them so must be obtained from diet (9 of them) Conditionally essential amino acids amino acid that"s normally nonessential, but must be supplied by the diet in special circumstances when need for it exceeds body"s ability to make it. Peptide bond connects acid end of 1 amino acid with amino end of another, forming a link in protein chain. Dipeptide 2 amino acids bonded together. Tripeptide 3 amino acids bonded together. Polypeptide many (10 or more) amino acids bonded together (can be linked in variety of sequences)
