glyceride glyc·er·ide (glĭs'ə-rīd')
A natural or synthetic ester of glycerol and fatty acids.
Any of various esters formed when glycerol reacts with a fatty acid. The fatty acids can react with one, two, or all three of the hydroxyl groups of the glycerol, resulting in mono-, di-, and triglycerides, respectively. Triglycerides are the main components of plant and animal oils and fats.
