What is true of saturated fatty acids?
they have longer molecules with a bent shape.
they are liquids at room temperature.
they have the maximum number of hydrogen atoms.
they make up most vegetable fats.

 They have the maximum number of hydrogen atoms.

Saturated fatty acids have the maximum number of hydrogen atoms.

Explanation:

A fatty acid that doesn’t contain any double bond between carbons in their molecular structure is known as saturated fatty acid. They are also incapable of absorbing hydrogen in their molecular structure thus the name.

Saturated fatty acids are generally found in animal fats like butter, milk and dairy products. Because of the higher melting point of those fatty acids, they are generally found in solid state at reem temperature.
