HUMAN NUTRITION

Detailed explanation-1: -Amino acids are the monomers that make up proteins. Each amino acid has the same fundamental structure, which consists of a central carbon atom, also known as the alpha () carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom.

Detailed explanation-2: -Every amino acid also has another atom or group of atoms bonded to the central atom known as the R group (Figure 1). The name “amino acid” is derived from the fact that they contain both amino group and carboxyl-acid-group in their basic structure. As mentioned, there are 20 amino acids present in proteins.

Detailed explanation-3: -So we can call protein monomer names as amino acids. Every amino acid consists of hydrogen, amine, R group, and the carboxyl group.

Detailed explanation-4: -A polymer composed of amino acid monomers is called a polypeptide or a protein.
