BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The four main organic compounds that make up living things are carbohydrates, lipids, nucleic acids, and . Lipids are one of four classes of biochemical compounds, which are compounds that make up living things and carry out life processes.

Detailed explanation-2: -Four elements, hydrogen, carbon, oxygen and nitrogen, are the major components of most organic compounds. Consequently, our understanding of organic chemistry must have, as a foundation, an appreciation of the electronic structure and properties of these elements.

Detailed explanation-3: -All cells are made from the same major classes of organic molecules: nucleic acids, proteins, carbohydrates, and lipids.

Detailed explanation-4: -Most organic compounds contain carbon and hydrogen, but they may also include any number of other elements (e.g., nitrogen, oxygen, halogens, phosphorus, silicon, sulfur).

Detailed explanation-5: -The four main classes of organic compounds (carbohydrates, lipids, proteins, and nucleic acids) that are essential to the proper functioning of all living things are known as polymers or macromolecules. All of these compounds are built primarily of carbon, hydrogen, and oxygen but in different ratios.
