Document Summary
Basic structure of an amino acid and what are the different classes of amino acids. Basic structure: central carbon attached to an amino group, a carboxyl group, h atom, and an r group (1 of the 20 other amino acids) Amino acids are often referred to as amino acid residues (simply, residues) Differences in structure of amino acids gives different properties. Different classes of amino acids: nonpolar, uncharged, positively charged (basic, negatively charged (acidic) Chemistry of the peptide bond and how it is formed. Peptide bond is formed through a dehydration synthesis reaction between the amino group of one amino acid and the carboxyl group of another amino acid. Amino acids are only added to the carboxyl group of the growing strand. Results in one end of the strand having an amino group (n-terminal end) and other end with carboxyl group (c-terminal end)
