NTR 108 Lecture Notes - Lecture 5: Active Transport, Enterohepatic Circulation, Blood Sugar
Document Summary
R - groups are the side chains that make the amino acid diff. Peptide bond - 2 animo acids linked together. Dna cell in animo acid sequence is created. In ribosome, rna translate into protein - the animo acid in correct order. Essential animo acids (eea): can not be made by body, need from food. Nonessential animo acids (neea): can be made by body. Energy - 4kcal/g - (10% of usage) - minor role. Enzyme: speed up and control chemical reactions in digestion, absorption, metabolism. Immune function: antibodies regulation of guild balance (edema) maintenance of acid-bace balance involved in blood clotting delivery of oxygen to tissue transport proteins: albumin and lipoprotein. Pepsin (enzyme that"s released from stomach) breaks more bonds. Denaturation: loss of protein function and exposure of peptide bonds for digestion. Digestion, protein broken down to individual animo acids. The body use the animo acids to make new tissues & maintenance the existing ones.
