Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Fatty acids and glycerol form the polymer ____
A
carbohydrates
B
lipids
C
proteins
D
nucleic acids
Explanation: 

Detailed explanation-1: -A lipid is a polymer composed of three fatty acid molecules and one glycerol molecule. Lipids produce a special polymer form which is considered to be a key component of cell membranes and hormones. Lipids help to store energy, provide cushion, protect tissues, separate the body, and form membranes of cells.

Detailed explanation-2: -Triglycerides are simple lipid which constituted one molecule of glycerol and three molecules of fatty acids. Triglyceride is the storage form of lipid, which is used for energy production. Triglycerides are found circulating in the blood where they are transported by very-low-density lipoprotein (VLDL).

Detailed explanation-3: -A lipid is a polymer made up of three molecules of fatty acids and one molecule of glycerol. They are the main constituents of body fat in humans and other animals, as well as vegetable fat.

Detailed explanation-4: -Lipids have four main types of polymers: triglycerides, phospholipids, waxes, and steroids.

Detailed explanation-5: -Fats and oils are esters of glycerol and three fatty acids. They are important in the diet as energy sources and as sources of essential fatty acids and fat-soluble vitamins, which tend to associate with fats. They also contribute satiety, flavor, and palatability to the diet.
