Usually they have an EVEN # of carbons (reactive and toxic) [i.e. palmitic acid] Fatty acid ester- A fatty acid in which the carboxylic acid group has reacted with the alcohol group of another molecule (often glycerol) to form a stable, less reactive ester bond Triglyceride- A glycerol (three carbon with three OH backbone) with three esterfied fatty acid side chains- AKA triacyglycerol TAG- Table, non polar, hydrophobic...
