The primary structure of proteins consists of a sequence of amino acids linked together by peptide bonds and includes any disulfide bonds.
举一反三
- A chain of 5 amino acids contains how many peptide bonds ?</p></p>
- The spatial conformation of a protein mainly depends on A: α-helix and β-sheet B: the sequence of amino acids in polypeptide chain C: disulfide bonds in polypeptide chain D: hydrophobic effects in polypeptide chain E: hydrogen bonds in polypeptide chain
- 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.
- Proteins are natural polymers of amino acids with primary structure, secondary structure, tertiary structure and quaternary structure.
- The primary structure of a food protein molecule refers to a linear sequence of amino acids connected by hydrogen bonding.
