Document Summary
Relate it to glucogenesis, citric acid cycle, electron transfer chain, anaerobic metabolism, and aerobic metabolism. Deficiency is rare in the us, as economy gets better, the portion in animal foods increases become toxic: bad to eat too much because it has a nitrogen in amino group and can. Most of the world relies on plant proteins because it is cheaper: 2/3 is animal products. Amino acids: central chain, hydrogen chain, amino group, acid group, and unique side chain(20 diff) Transamination: essential amino acids (9) and nonessential amino acids. Alpha ketoglutamate & pyruvate =key metabolic intermediates to give rise to energy. Chemical bond that attaches protein bonds together= peptide bond (btwn acid group and nitrogen) Dipeptide= 2 amino acids one peptide bond. One or more polypeptide chains 3d shape. In addition with this, protein protein interactions. Join together by sharing amino group/ hydroxyl group. Connective tissue proteins and collagen are elongated. Caused by one amino acid, interact with neighbor hemoglobins.
