Question

Is protein organic or inorganic?

Answer 1

Hint: The classification of any compound or series of compounds as organic or inorganic can be done on the basis of its constituent elements. For any compound to be called organic it must contain plenty of carbon atoms in it.

Complete answer:
Proteins are one of the most essential biomolecules that the human body uses as nutrients. Proteins serve vital functions in our body and are responsible for our growth and wear and tear of cells and tissues of the body. Many parts of our body are dead cells made of proteins. Proteins are present in our skin, nails, hair and many other parts. Protein helps build muscular strength and at the same time the antibodies released in our body on getting exposed to any infection are proteins only.
The proteins are macromolecules (large molecules having long and complex chains of atoms linked to each other forming complex structures). The building blocks of proteins are the repeating units of amino acids.
Amino acids are molecules consisting of two functional groups namely the carboxylic acid and amino group linked to the central carbon atom that also contains hydrocarbon side chains that can be aliphatic or aromatic in nature.
When more than hundred amino acids (same or different in kind) get linked to one another through peptide linkages to form complex molecules having high molecular masses, they are called proteins.
Though proteins contain elements like nitrogen and oxygen, the core of these molecules are carbon atoms that are the central part of amino acids and also present in the hydrocarbon chains attached to the.
Due to the large excess of carbon atoms present in proteins, they are organic molecules and not inorganic.

Note:
Amino acids that are the building blocks of proteins can be both essential and non-essential in nature. The essential amino acids are not synthesized by the human body and need to be consumed in appropriate amounts from the outside. The non-essential ones are produced inside the body in sufficient amounts.
