BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Protein is mainly formed by carbon, hydrogen, nitrogen and oxygen. Amino acids join to form proteins. Each amino acid is formed with one basic group NH2 and one acidic group(COOH).

Detailed explanation-2: -In addition to carbon, hydrogen and oxygen atoms, all proteins contain nitrogen. Proteins are large biological molecules or macromolecules consisting of one or more long chains of amino acids and carboxylic acid. Therefore, proteins are macromolecules formed by amino acids.

Detailed explanation-3: -In addition to carbon, hydrogen, and oxygen atoms, all proteins contain nitrogen and sulfur atoms, and many also contain phosphorus atoms and traces of other elements.

Detailed explanation-4: -Proteins are one of the primary constituents of living matter. They consist of long chains of amino acids, which are bonded together by peptide linkages and thus called polypeptides. There are about 20 amino acids, and the atoms most prevalent in these are carbon, hydrogen, oxygen, nitrogen, and sulfur.

Detailed explanation-5: -Nitrogen is in all amino acids and nucleotides, and therefore in all proteins and nucleic acids.
