Glucose

Glucose is a type of sugar that serves as a primary source of energy for living organisms. It is a simple sugar, also known as a monosaccharide, and is readily used by the body for cellular respiration, which produces the energy needed for various biological processes.

Structure of Glucose

Glucose has a chemical formula of C₆H₁₂O₆, indicating that it is composed of 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms. Its molecular structure is a six-carbon ring composed of hydroxyl groups (-OH) and a carbonyl group (C=O).

Role in the Body

Glucose is essential for the functioning of the human body. When consumed through food, it is broken down in the digestive system and absorbed into the bloodstream. From there, it is transported to cells throughout the body, where it is used for energy production.
