Lipid Synthesis 1. Fatty acid synthesis
... Fatty acids are a more efficient form of energy storage than carbohydrates because they are less hydrated, as result of fewer hydroxyl groups being available for hydrogen bonding. The energy content of fat tissue is 38 kJ/gm compared to 17 kJ/gm for carbohydrates. The processes of fatty acid degrada ...
