Document Summary
Proteins part 1: more protein does not equal bigger muscles. Protein- vital to life: protein is found in almost every part of our body, from out hair to our toenail to our teeth and bones, hormones. Functions of protein in the body: structural, skin, nails, bone, muscle, regulation and maintenance of body functions, blood clotting, fluid balance, hormone and enzyme production, immunity, energy- provides 4 kcal/gram, gluconeogenic. Cho: peptide bond: bond between aa forming proteins, number of aa, dipeptide: 2, tripeptide : 3, oligopeptide: >3, <50, polypeptide: 50, foods usually have polypeptides chains with 100+ aa. Aa structure: amine group, acid group, hydrogen, r group. Eaa: need to consume these aa drom diet, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, theroinine, tryptophan, valine. 6 will not increase muscle mass on its own. Protein synthesis: dna is composed of nucleotides which make of the code for dna.
