HUMAN NUTRITION

Detailed explanation-1: -A common fat molecule or triglyceride. These types of molecules are generally hydrophobic and, while they have numerous functions, are probably best known for their roles in body fat and plant oils. A triglyceride molecule derived from two types of molecular components-a polar “head” group and a nonpolar “tail” group.

Detailed explanation-2: -Triacylglycerols are nonpolar, hydrophobic, and insoluble in water. This is due to the ester linked bond between the polar hydroxyls of glycerol and the polar carboxylates of the fatty acids. Common triacylglycerols are vegetable oils, dairy products, and animal fat.

Detailed explanation-3: -The head is the hydrophilic part, and the tail contains the hydrophobic fatty acids. In a membrane, a bilayer of phospholipids forms the matrix of the structure, the fatty acid tails of phospholipids face inside, away from water, whereas the phosphate group faces the outside, aqueous side.

Detailed explanation-4: -The resulting structure iscalled a lipid bilayer. Then triglycerides, In phospholipids, the two fatty acids are hydrophobic, or insoluble in water. But the phosphate group is hydrophilic, or soluble in water.
