One lipid-cholesterol system that has recently been studied intently is the lipid raft. Lipid rafts are cholesterol-enriched gel domains that have been potentially implicated in certain cell signaling processes, [12] but the subject remains controversial, with some researchers doubting even their existence in vivo.

Lipid metabolism is the synthesis and degradation of lipids in cells, involving the breakdown and storage of fats for energy and the synthesis of structural and functional lipids, such as those involved in the construction of cell membranes. In animals, these fats are obtained from food and are synthesized by the liver. [1]
Carbohydrates, on the other hand, are more highly hydrated. For example, 1 g of glycogen binds approximately 2 g of water, which translates to 1.33 kcal/g (4 kcal/3 g). This means that fatty acids can hold more than six times the amount of energy per unit of stored mass.
Metabolic water refers to water created inside a living organism through metabolism, by oxidizing energy-containing substances in food and adipose tissue. Animal metabolism produces about 107–110 grams of water per 100 grams of fat , [ 1 ] 41–42 grams of water per 100 g of protein , and 60 grams of water per 100 g of carbohydrate .

The breakdown of this fat is known as lipolysis. The products of lipolysis, free fatty acids , are released into the bloodstream and circulate throughout the body. During the breakdown of triacylglycerols into fatty acids, more than 75% of the fatty acids are converted back into triacylglycerol, a natural mechanism to conserve energy, even in ...
