What's the difference between a fatty acid and a monoglyceride?

Answer 1

A monglyceride is the ester that is formed by reacting one equivalent of a given fatty acid with one equivalent of glycerol.

Structurally therefore, in a monogyceride, the -COOH group of the fatty acid is replaced by -COO- (CH2)(CH)(OH)2.

Answer 2

In monoglyceride only one hydroxylic group of Glycerol forms an ester with one Carboxylic group of one fatty acid(R'-OOC-R").In Tri-Glyceride three hydroxyl grops of Glycerol combine with three carboxylic groups(ester linkage) of 3 (same or different) fatty acids-Fats and oils..
