Does the amino acid proline contain a planar ring? If not why?
Does the amino acid proline contain a planar ring? If not why?
Homework Answers
Answer:
Unlike other amino acids proline has no planer ring but cyclic ring
or pyrrole ring.it is created by the covalent bond between the
amino group of CA and R group.
It has no NH backbone to bond(hydrogen) and contains a secondary
amino group

Which three statements about amino acids are true? Use this chart of amino acid structures for reference. Lysine has one stereocenter (chiral center). Methionine is a thiol. The Leu side chain does not form hydrogen bonds with other amino acids. The form of glycine used by the human body is D-glycine. Ser and Thr are polar amino acids. Proline has an overall charge at physiological pH (7.4).
