What is a diglyceride?

Explanation:
A diglyceride is a lipid built on a glycerol backbone with two fatty acids esterified to two of its three hydroxyl groups, leaving one site free. This distinguishes it from a triglyceride, which has three fatty acids attached, and from a monosaccharide or a protein, which are carbohydrates and amino-acid polymers, respectively. So the defining feature is glycerol plus two fatty acid chains, making it a diacylglycerol rather than another type of biomolecule. In nutrition, you might encounter diglycerides as intermediates formed during fat digestion or used as emulsifiers in foods.
