FNN 100 Lecture 5: protein
Document Summary
Fnn protein protein is long chains of amino acids. N enters food chain through n- xing bacteria in roots. 20aa"s indispensable, dispensable, conditionally indispensible essential aa"s used to make indispensable aa"s and other n compounds contain:amino group, carboxyl group, and h atom, and c side chain side chain noted as r . Histidine despensable (non-essential) aa"s can be synthesized in the body through transamination. Conditionally indespensable aa"s not synthesized at a rate to meet the body"s needs. Protein structure the structure determines function dipeptide: 2 aa residues tripeptide: 3 aa residues ogliopeptide: 4-9 peptide residues. Condensation of 2 aa"s to form a dipeptide acid group+ amine group form peptide bond and create a dipeptide. Protein structure primary linear sequence of aa secondary. Quaternary bond between subunits that comprise a functional protein. Why do proteins fold? so they can carry out their function.
