Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of these describes a saturated fatty acid?
A
All C-H bonds are full
B
They form straight chains
C
They are solids at room temp.
D
All of the above
Explanation: 

Detailed explanation-1: -A saturated fatty acid is a type of fatty acid that lacks unsaturated linkages between carbon atoms. Because of the lack of double bonds, this type of fatty acid can no longer absorb any more hydrogen; it is saturated. Saturated fatty acids are commonly found in animal fats.

Detailed explanation-2: -Common dietary saturated fatty acids include stearic acid, palmitic acid, myristic acid, and lauric acid.

Detailed explanation-3: -Saturated fatty acids lack double bonds between the individual carbon atoms, while in unsaturated fatty acids there is at least one double bond in the fatty acid chain. Saturated fats tend to be solid at room temperature and from animal sources, while unsaturated fats are usually liquid and from plant sources.

Detailed explanation-4: -So, the correct answer is ‘Palmitic acid’.
