Verified step by step guidance1
Understand the structure of a fat molecule, also known as a triglyceride, which is a type of lipid.
Recognize that a triglyceride is composed of a glycerol backbone and fatty acids.
Recall that the glycerol molecule has three hydroxyl (OH) groups.
Each hydroxyl group of the glycerol can form an ester bond with a fatty acid, resulting in the attachment of three fatty acids.
Conclude that a typical fat molecule, or triglyceride, contains three fatty acids attached to the glycerol backbone.
