Fat and protein metabolism

10 videos
1D: The ham and cheese sandwich you just enjoyed need to be processed by the cells of your body. In addition to the sweet glucose we happily consume, we also take in fat (great for storing energy compactly) and proteins (which can be metabolized to produce energy or used as building blocks for innumerable parts of your body). These tutorials will shed light on the key metabolic pathways governing the metabolism of fats and proteins.
