Examples of straight-chain fatty acids include ${\mathrm{C}}_{19}{\mathrm{H}}_{39}\mathrm{COOH}$, ${\mathrm{C}}_{19}{\mathrm{H}}_{31}\mathrm{COOH}$ and ${\mathrm{C}}_{19}{\mathrm{H}}_{29}\mathrm{COOH}$.

Deduce the number of $\mathrm{C}=\mathrm{C}$ bonds present in one molecule of each fatty acid.

Deduce the least stable of the three fatty acids and explain your reasoning.

There are several types of lipids in the human body. One of these types, triglycerides, might be made of fatty acids with different degrees of saturation.

State one example of each of the following types of fatty acids: saturated, monounsaturated, and poly-unsaturated

There are several types of lipids in the human body. One of these types, triglycerides, might be made of fatty acids with different degrees of saturation.

Describe, by copying and completing the equation below, the condensation of glycerol and the three fatty acids named below to make a triglyceride.palmitic acid oleic acid, and linolenic acid.
