Question

Select the true statements.
A peptide has one amino acid.
A peptide has carbon, nitrogen, oxygen, and hydrogen atoms.
A peptide bond links amino acids together.
Two amino groups combine to make a peptide bond.

Answer 1

True:
- A peptide has carbon, nitrogen, oxygen, and hydrogen atoms.
- A peptide bond links amino acids together.

False:
- A peptide has one amino acid. (A single amino acid is not a peptide; peptides are chains of two or more amino acids.)
- Two amino groups combine to make a peptide bond. (A peptide bond forms between the carboxyl group of one amino acid and the amino group of another, not between two amino groups.)
