The most abundant of the four major classes of biomolecules, which also include proteins, lipids, and nucleic acids. They fill numerous roles in living things, such as the storage and transport of energy (starch, glycogen) and structural components (cellulose in plants, chitin in animals). Additionally, these and their derivatives play major roles in the working process of the immune system, fertilization, pathogenesis, blood clotting, and development.

Carbohydrates

Explanation:

Carbohydrate is a macronutrient formed primarily of carbon, hydrogen and oxygen molecules. This macronutrient when ingested and absorbed is responsible for releasing glucose, providing energy to cells as the primary source of cellular energy, and maintaining glycemic metabolic maintenance for the body to continue to function well. Carbohydrates are the most abundant biomolecule present in the body and play a key role in many parts of our body.

Carbohydrates are involved in energy storage and transport, immune system, reproductive system, fertilization, blood clotting, among other processes that are vital in the body.
