HES 250 Lecture Notes - Lecture 3: Amine, Ephedrine, Carboxylic Acid
Document Summary
Structure: primary sequence of a chain of amino acids, secondary linked by hydrogen bonds, tertiary attractions between alpha helixes and beta pleated sheets, quaternary more than 1 amino acid chain. Amino acid: there are 20, essential (cid:894)(cid:862)co(cid:373)plete(cid:863)(cid:895) a(cid:373)i(cid:374)o acids. There are 9, and they must be obtained through diet: nonessential (cid:894)(cid:862)i(cid:374)co(cid:373)plete(cid:863)(cid:895) a(cid:373)i(cid:374)o acids. Complementary proteins: proteins that can be combined to compensate for deficiencies in essential amino acid content in each protein. Protein supplements: milk protein (animal based) Strong muscle building capability: soy protein (plant based) Study: consumption of fat-free milk after resistance exercise promotes greater lean mass accretion than does consumption of soy or carbohydrate in young, novice male weightlifters. Bcaa, serotonin, and central fatigue: serotonin increases the perception of effort, serotonin is produced from tryptophan, bcaas block tryptophan from entering brain cells, thus reducing serotonin. Supplements with multiple ingredients that include specific amino acids: common ingredients:
