A
triglyceride (
TG,
triacylglycerol,
TAG, or
triacylglyceride) is an
ester derived from
glycerol and three
fatty acids ( +
glyceride). Triglycerides are the main constituent of
body fat in humans and animals, as well as
vegetable fat. They are also present in the blood to enable the bidirectional transference of
adipose fat and blood glucose from the liver, and are a major component of
human skin oils.
