Document Summary
Amino acids: nigtrogen containing molecules that combine to form proteins, essential amino acids. Cannot be produced by our bodies or can not be produced by our bodies in sufficient amounts. Must be obtained from food: nonessential amino acids. Made by body: structure of an amino acid. Side chain the distinguisihing characteristic of amino acids due to shape. Based on the side group, they are going to bond differently. Determines folding and shape therefore function: transamination. Taking an amino acid and transferring the amine group to another amino acid in the side chain: protein turnover: synthesis and breakdown. Amino acids from food and the breakdown of cells. Excess nitrogen in the form of free ammonia used to synthesise urea in the liver. Use the genetic information in dna to make rna: mrna copies the genetic information found in dna and. When two amino acids join together in a peptie bond, they form a dipeptide.
