Question

question 40
saturated fatty acids are:
a not completely saturated with hydrogen
b all of these
c are liquid at room temperature
d completely saturated with hydrogen
e none of these

Explanation:

Saturated fatty acids have no double bonds between carbon atoms in their hydrocarbon chains, meaning they are completely saturated with hydrogen. Unsaturated fatty acids have double bonds (so are not completely saturated with hydrogen). Saturated fatty acids are usually solid at room temperature (e.g., butter), while unsaturated (like many plant oils) are liquid at room temperature.

Answer:

D. completely saturated with hydrogen
