A chain of 5 amino acids contains how many peptide bonds ?
举一反三
- 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.
- The primary structure of proteins consists of a sequence of amino acids linked together by peptide bonds and includes any disulfide bonds.
- 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 covalent bond between two adjacent amino acids in a protein chain is called a ___________; the chain of amino acids is also known as a polypeptide.
- The spacial conformation of protein is mainly determined by: () A: the<br/>sequence of amino acid B: α-helix<br/>and β-pleated sheets C: the<br/>side chain of amino acid in the peptide D: peptide<br/>bond in the peptide chain E: the<br/>location of disulfide bond in the peptide chain
