Describe the process of fat storage (triacylglycerol synthesis)AND mobilization (triacylglycerol lipolysis)in adipose tissue-be sure to include how these processes are regulated (i.e.,the signals involved).

Essential fatty acids are classified as such because we cannot synthesize them from other fatty acids and they are required for the synthesis of prostaglandins,thromboxanes,and leukotrienes.

Once a micelle,containing lipids and lipid-soluble compounds,enters the enterocyte,it is referred to as a chylomicron.

Unlike long-chain fatty acids,short-chain fatty acids from the diet leave the enterocyte via the portal vein and go directly to the liver.
