Question

Triglycerides are formed by the esterification of one glycerol molecule with three fatty acids. When two of these are the same (stearic acid in this case) and one is different (myristic acid), the different fatty acid can be esterified in three positions on the glycerol backbone, leading to three different triglycerides. Stereoisomers do not apply in this context as the fatty acids mentioned do not have chiral centers that would lead to stereoisomerism.
