belka [17]

Answer:

This question describes a PROTEIN

Explanation:

Proteins are one of the four biological molecules in living systems. It is a biological polymer composed of monomeric units called amino acids, which are chemically joined together by peptide bonds.

An amino acid structurally consists of a central carbon atom bonded to an hydrogen atom, carboxylic acid group (-COOH), an amine group (-NH2) and a R side chain, which distinguishes one amino acid from another. Since all amino acids have a nitrogen-containing amine group, all proteins also contains nitrogen in their structure. Hence, a protein consist of an hydrocarbon (CHO) with a nitrogen atom.
