摘要
Glucose is central to energy consumption. Carbohydrates, lipids, and proteins all ultimately break down into glucose, which then serves as the primary metabolic fuel of mammals and the universal fuel of the fetus. It serves as the major precursor for the synthesis of different carbohydrates like glycogen, ribose, and deoxyribose, galactose, glycolipids, glycoproteins, and proteoglycans. On the contrary, in plants, glucose is synthesized from carbon dioxide and water (photosynthesis) and stored as starch. At the cellular level, most often, glucose is the final substrate that enters the tissue cells and converts to ATP (adenosine triphosphate).ATP is the energy currency of the body and is consumed in multiple ways including the active transport of molecules across cell membranes, contraction of muscles and performance of mechanical work, synthetic reactions that help to create hormones, cell membranes, and other essential molecules, nerve impulse conduction, cell division and growth, and other physiologic functions.
