Stearic acid and oleic acid are common fatty acids found in mammals. The formula for stearic acid is C18H36O2 and the formula for oleic acid is C18H34O2From this information we can conclude that:  oleic acid is saturated and stearic is unsaturated.   oleic acid and stearic acid are both saturated.   there is insufficient information to differentiate between them in relation to the degree of saturation.   stearic acid is saturated and oleic is unsaturated.   oleic acid and stearic acid are both unsaturated.

The correct answer is: stearic acid is saturated and oleic is unsaturated.

Here's why:

1. The degree of saturation of a fatty acid is determined by the presence or absence of double bonds in its carbon chain. Saturated fatty acids have no double bonds, meaning they have the maximum number of hydrogen atoms attached to each carbon atom. Unsaturated fatty acids, on the other hand, have one or more double bonds, meaning they have fewer hydrogen atoms.

2. Stearic acid (C18H36O2) has no double bonds in its carbon chain, as indicated by the maximum number of hydrogen atoms (2n+2, where n is the number of carbon atoms). Therefore, it is a saturated fatty acid.

3. Oleic acid (C18H34O2), on the other hand, has two fewer hydrogen atoms than stearic acid, indicating the presence of a double bond in its carbon chain. Therefore, it is an unsaturated fatty acid.
