- 3.A 6-year-old African American girl with speech delay is found to have a large, abnormal peak when blood amino acids are measured. The abnormal amino acid migrates toward the cathode, indicating a positively charged side group in addition to its carboxyl and amino groups. Which of the following amino acids is most probable?
- The primary structure of a food protein molecule refers to a linear sequence of amino acids connected by hydrogen bonding.
- The primary structure of proteins consists of a sequence of amino acids linked together by peptide bonds and includes any disulfide bonds.
- Proteins are large biological molecules consist of which of the following amino acids?: D-α-amino acids|D-β-amino acids|L- and D-β-amino acids|L-α-amino acids|L-β-amino acids
- The correct descriptions about peptide are A: A compound formed of two or more amino acids linked by peptide bonds. B: The amino acids that make up the peptides are residues. C: The peptide chain has amino terminus and carboxyl terminus. D: Oligopeptides less than 10 amino acids don’t have function.
