Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How is the structure of saturated fats different from that of unsaturated fats?
A
All of the carbons in the hydrocarbon tails of saturated fats are bonded to one another with double bonds.
B
Saturated fats have three hydrocarbon tails bonded to the glycerol molecule instead of just two.
C
The hydrocarbon tails in a saturated fat have the maximum number of hydrogens possible.
D
Saturated fats have no oxygen present.
Explanation: 

Detailed explanation-1: -Correct answer: In saturated fats, the carbons contain the maximum amount of hydrogens bonded to them. Explanation: In saturated fats, the carbons have single bonds between them and the maximum number of hydrogen atoms.

Detailed explanation-2: -Saturated Hydrocarbons-contain only carbon-carbon single bonds. Unsaturated Hydrocarbons-contain carbon-carbon double or triple bonds (more hydrogens can be added). In the carbon-carbon double bond, two pairs of electrons are being shared, leaving the carbon free to bond to two other things.

Detailed explanation-3: -The terms saturated and unsaturated refer to whether or not double bonds are present between the carbons in the fatty acid tails. Saturated tails have no double bonds and as a result have straight, unkinked tails. Unsaturated tails have double bonds and, as a result, have crooked, kinked tails.
