摘 要：Fats is the general name given to a category of lipids usually referred to as acylglyc-erides, which are esters in which two or three fatty acids are bonded to a glycerol molecule forming monoglycerides, diglycerides, or triglycerides, respectively. The most common fats are triglycerides; these are triesters of glycerol and fatty acids, and can be solid or liquid at room temperature depending on their particular structure and composition. Although the names "oils," "fats," and "lipids" are widely used to refer to fats, the words oils and fats usually apply to lipids that are liquid and solid, respectively, at ambient temperature.
