Triglycerides

A **triglyceride** (**TG**,**triacylglycerol**, **TAG**, or**triacylglyceride**) is an [|ester] derived from [|glycerol] and three [|fatty acids]. [|[1]] There are many triglycerides, and depending on the oil source, some are highly unsaturated, some are not. Saturated compounds are "saturated" with hydrogen — all available places where hydrogen atoms could be bonded to carbon atoms are occupied. Unsaturated compounds have double bonds (C=C) between carbon atoms, reducing the number of places where hydrogen atoms can bond to carbon atoms. Saturated compounds have single bonds (C-C) between the carbon atoms, and the other bond is bound to hydrogen atoms (for example =CH-CH=, -CH 2 -CH 2 -, etc.).
