Glycerol Catabolism

The video explains how fats are metabolized, focusing on glycerol's role. Glycerol, a byproduct of fat breakdown, is converted into glycerol phosphate, then into dihydroxyacetone phosphate (DHP), and finally into glyceraldehyde 3-phosphate (G3P). This process involves enzymes like glycerol kinase and glycerol phosphate dehydrogenase. The conversion yields NADH and ATP, which are used in the respiratory chain for energy. The body's efficient use of glycerol is likened to the Native American practice of using all parts of the buffalo.
