Question

Which of the amino acids has hydroxyl in its R-group?

• A. Serine
• B. Alanine
• C. Arginine
• D. Proline

Answer 1

The correct option is A Serine

The proteins are made up of amino acids. The amino acids have the carboxyl group at one end and an amine group at the other end of a side chain (R). The amino acids are linked together by peptide bonds to form a protein. The peptide bond is formed by the linkage of the carboxyl group of one amino acids with the amino group of the amino acids.

Serine has the molecular formula of C${}_3$H${}_7$NO${}_3$ and has hydroxyl in its R-group.

So, the correct answer is option A.
