ANSI 3543 Lecture Notes - Lecture 6: Infertility, Phenylalanine, Birth Weight
Document Summary
Not all n in the diet is an amino acid urea is but isn"t amino converted to n acid. Composition: c: 15, h: 7, o: 23, n: 16% 16 g n per 100 g protein = 6. 25. Primary dry matter constituent of body organs. Protein requirements: more when young than when mature. Enzymes: lipase, maltase, trypsin are all proteins, function in digestion and metabolism. Hormones: growth hormone, insulin are proteins, regulate metabolism. Immune system: antibodies are proteins, igg, iga, igm. Transport within the body: chylomicron, albumin. All proteins are made up of simple units called amino acids. 200 amino acids occur naturally in nature: only 20-22 commonly found in large quantities in protein. Essential amino acids: phenylalanine, valine, threonine, tryptophan, isoleucine, methionine, histidine, arginine, leucine, lysine. Amino acids linked together with peptide bonds: couple carboxyl group with alpha amino group. Amino acids as sources of energy: carbon skeletons will be used as energy. Enter krebs cycle and converted to glucose.
