BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Amino acids contain the elements carbon, hydrogen, oxygen and nitrogen. There are amino groups in the basic structure of every amino acid.

Detailed explanation-2: -There are about 20 amino acids, and the atoms most prevalent in these are carbon, hydrogen, oxygen, nitrogen, and sulfur. Each amino acid contains a carboxylic acid end and an amino end.

Detailed explanation-3: -Proteins are compounds composed of carbon, hydrogen, oxygen, and nitrogen, which are arranged as strands of amino acids . They play an essential role in the cellular maintenance, growth, and functioning of the human body.

Detailed explanation-4: -Proteins are made of carbon, hydrogen, oxygen, and nitrogen (CHON).

Detailed explanation-5: -These are arginine (Arg), lysine (Lys), and histidine (His). Their side chains contain nitrogen and resemble ammonia, which is a base. Their pKa’s are high enough that they tend to bind protons, gaining a positive charge in the process.
