Glucose is central to energy consumption. Carbohydrates and proteins ultimately break down into glucose, which then serves as the primary metabolic fuel of mammals and the universal fuel of the fetus. Fatty acids are metabolized to ketones. Ketones cannot be used in gluconeogenesis. Glucose serves as the major precursor for the synthesis of different carbohydrates like glycogen, ribose, deoxyribose, galactose, glycolipids, glycoproteins, and proteoglycans. On the contrary, in plants, glucos...
