C6H12O6, commonly known as glucose, is a simple sugar and an essential carbohydrate in biology. It serves as a primary energy source for living organisms, providing fuel for cellular processes. Glucose is produced during photosynthesis in plants and is found in various foods, especially fruits and honey. In the human body, glucose is absorbed into the bloodstream and transported to cells, where it is utilized for energy. The hormone insulin helps regulate blood glucose levels, ensuring that cells receive the necessary amount for metabolism. Abnormal glucose levels can lead to health issues, such as diabetes.
