Module 5: what is protein, food sources, amino acids, structure, functions. Amino acids >> c,h,o,n and molecules in different sequences. What is protein? sometimes s, with various side chains attached. N enters food chain through n- fixing bacteria in ____________ Eaas used to make dispensable aas & other n compounds. Contain: amino group (nh2 (cooh), an h atom attached to a central c & a side chain. Side chain often noted as r r1 . 8 types of aa, based on ____________________ Indispensable (essential) aas: cannot be synthesized in the body - must be supplied by the diet. Dispensable (non- essential) aas: can be synthesized in the body through. Conditionally indispensable aas not synthesized at a rate to meet body"s needs. Polypeptides: many aas> many peptide bonds (insulin 51 aa residues) Secondary (2 ): 3d elements - alpha & beta helices, sheets. Quaternary (4 ): bonds between subunits (_______________) that comprise a functional protein.
