Fate of Pyruvate Under Anaerobic Conditions

In the human body, carbohydrates play critical roles in energy metabolism and cellular functions. Monosaccharides, the simplest forms of carbohydrates, can undergo various biochemical transformations. One of the most common monosaccharides is glucose, which is crucial for energy production. When glucose is broken down in a metabolic pathway known as glycolysis, pyruvate is formed as an end product. Depending on the oxygen availability, pyruvate can be converted into different metabolites.
