Triglycerides are built on which backbone?

Explanation:
Triglycerides are built on a glycerol backbone, a three-carbon alcohol with three hydroxyl groups that serve as attachment points for fatty acids. Each fatty acid forms an ester bond with one of those hydroxyls, so a triglyceride consists of glycerol with three fatty acids kissing onto it. The other molecules listed are carbohydrates: glucose and ribose are sugars, and sucrose is a disaccharide made from glucose and fructose—none of these serve as the glycerol scaffold for triglycerides.
