Class 12 Chemistry Chapter 14 Biomolecules – Important Topics

Biomolecules forms a part of Biochemistry which deals with chemical processes relating to all living organisms. Some of the important Biomolecules essential for the survival of living organisms include:

Carbohydrates: Carbohydrates are macronutrients and one of the three primary sources of nutrition for our bodies. It consists of Carbo, hydrogen and oxygen as its constituent particles.
Proteins: Proteins are the building blocks of life and form 60% of dry cells in the body and form the fundamental basis of the structure and functions of life. Proteins are made up of amino acids.
Enzymes: Enzymes are catalysts of biological systems. All enzymes are proteins, except for a small group of catalytically active RNA molecules or ribozymes.
Vitamins: Vitamins are natural and essential nutrients, which play a major role in the growth and development of the human body. These are divided into Water-soluble and Fat-soluble vitamins.
Nucleic Acid: Nucleic acids are long-chain polymeric molecules. The two main nucleic acids are DNA and RNA which are responsible for inheritance and gene transfer.
Hormones: Hormones are our body’s chemical messengers which are released in one tissue and to one or other tissues through the circulatory system. They are responsible for many bodily functions.
