Multiple Choice

How do fatty acids found in fats and other lipids differ from one another?

By the type of glycosidic bonds they form

By the number of phosphate groups attached to them

By the presence of nitrogen atoms in their structure

By the length of their carbon chains and the degree of saturation

Verified step by step guidance

Understand that fatty acids are carboxylic acids with long hydrocarbon chains, which can vary in length and saturation.

Recognize that the length of the carbon chain in fatty acids can differ, typically ranging from 4 to 28 carbon atoms.

Identify that the degree of saturation refers to the presence of double bonds in the carbon chain. Saturated fatty acids have no double bonds, while unsaturated fatty acids have one or more double bonds.

Note that the presence of double bonds affects the physical properties of the fatty acids, such as melting point and fluidity.

Conclude that fatty acids differ from one another primarily by the length of their carbon chains and the degree of saturation, rather than by glycosidic bonds, phosphate groups, or nitrogen atoms.
