The answer is the third one: fatty acids.

Explanation for each option:

  1. 3 carbons: This is incorrect. A triglyceride molecule does not always contain exactly 3 carbons. Instead, it is composed of a glycerol backbone and three fatty acid chains, which can vary in length and number of carbons.

  2. glycerols: This is incorrect. A triglyceride contains only one glycerol molecule, not three.

  3. fatty acids: This is correct. A triglyceride is formed by the esterification of one glycerol molecule with three fatty acid molecules.

  4. double bonds: This is incorrect. While fatty acids in a triglyceride can contain double bonds (making them unsaturated), a triglyceride does not always contain double bonds. It can be composed of saturated fatty acids, which have no double bonds.

Summary: A triglyceride always contains three fatty acids.

In each of the molecules drawn below, one chemical bond is circled. Decide whether this bond is likely to be polar or not. If the bond is polar, write down the chemical symbol for the atom which will have more negative charge.
