WebAcid-base properties and ionization of amino acids • Amino acids (AA) have at least two groups that can yield protons: amino (-NH2) and carboxyl (-COOH) • At acidic (low) pH, the carboxyl group is protonated and the amino acid is in the_____________form. • At pH 7, there is no net charge but a dipolar ion is observed. Web2 dagen geleden · This means that the only charged groups on a peptide are at the N- terminus (α -amino group), C- terminus (α -carboxyl) and on any ionized amino acid side chains. Key Icon The -C=O and -N-H groups of peptide bonds are polar, and therefore can participate in hydrogen bonding. incentives for small business owners
