Question

what group of organic molecules is made up of a sequence of an amion group, a carboxyl group, a hydrogen atom and a side chain bonded to the central carbon atom? a.proteins b.carbohydrates c.nucleic acids d.lipids

Answer 1

Option A, Proteins

Step-by-step explanation:

Proteins (Amino acids) consists of one alpha carbon with a valency of four, thus it needs to form four bonds to become a stable molecule.

Thus, protein bonds to the following-

a) A R - group which is nothing but a long molecular chain of carbon, hydrogen or oxygen

b) A carboxyl group

c) A hydrogen atom

and

d) An amino group.

Thus, option A is correct.

Answer 2

Protein is made up of a sequence of an amino group, a carboxyl group, a hydrogen atom and a side chain bonded to the centralcarbon atom.
