BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The building blocks of proteins are amino acids, which are small organic molecules that consist of an alpha (central) carbon atom linked to an amino group, a carboxyl group, a hydrogen atom, and a variable component called a side chain (see below).

Detailed explanation-2: -In structural biology, a protein subunit is a polypeptide chain or single protein molecule that assembles (or “coassembles") with others to form a protein complex. Large assemblies of proteins such as viruses often use a small number of types of protein subunits as building blocks.

Detailed explanation-3: -Proteins are made up of hundreds or thousands of smaller units called amino acids, which are attached to one another in long chains. There are 20 different types of amino acids that can be combined to make a protein.
