BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The most common method used to study protein structures is X-ray crystallography. With this method, solid crystals of purified protein are placed in an X-ray beam, and the pattern of deflected X rays is used to predict the positions of the thousands of atoms within the protein crystal.

Detailed explanation-2: -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-3: -An organic compound A of molecular formula C3H7O2N on reaction with Fe and conc. HCl gives a compound B of formula C3H9N.

Detailed explanation-4: -Proteins are considered organic molecules because of the chemical makeup of the amino acids that are their monomer. Each amino acid consists of a central carbon atom. This carbon atom is bound to a hydrogen atom, an amine group on one end, and a carboxyl group on the other end.
