BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Proteins contains nitrogen. They are large biological molecules or macromolecules, consisting of one or more long chains of amino acids (organic compounds composed of amine (−NH2) and carboxylic acid(−COOH)).

Detailed explanation-2: -Yes, nitrogen is an essential element for proteins. Nitrogen is act as a molecular building block of proteins and is also a fundamental component of amino acids. The protein needs nitrogen because of amino acids. There would be no protein, without amino acids and without protein, there are no enzymes.

Detailed explanation-3: -Based on these facts, and the different amino acid compositions of various proteins, the nitrogen content of proteins actually varies from about 13 to 19 percent. This would equate to nitrogen conversion factors ranging from 5.26 (1/0.19) to 7.69 (1/0.13).

Detailed explanation-4: -Proteins can be characterized as extremely long-chain polyamides. The amides contain nitrogen, and nitrogen composes about 16% of the protein atomic content.

Detailed explanation-5: -Proteins are made up of many amino acid units. The amino acid units have an amino group as part of the general structure. The amino group is also known as the functional group as amine which contains a Nitrogen atom. Therefore, the amino group will have the Nitrogen atom for the protein.
