HUMAN NUTRITION

Detailed explanation-1: -1: A phospholipid consists of a head and a tail. The “head” of the molecule contains the phosphate group and is hydrophilic, meaning that it will dissolve in water. The “tail” of the molecule is made up of two fatty acids, which are hydrophobic and do not dissolve in water.

Detailed explanation-2: -The heads (the phospho part) are polar while the tails (the lipid part) are non-polar. The heads, which form the outer and inner linings, are “hydrophilic” (water loving) while the tails that face the interior of the cell membrane are “hydrophobic” (water fearing).

Detailed explanation-3: -Phospholipids. Phospholipids consist of two hydrophobic “tails, ‘’ which are fatty acid chains, and one hydrophilic “head, ‘’ which is phosphate group.

Detailed explanation-4: -The hydrophobic, or “water-fearing, ‘’ part of a phospholipid consists of its long, nonpolar fatty acid tails. The fatty acid tails can easily interact with other nonpolar molecules, but they interact poorly with water.
