Detailed explanation-1: -Phospholipids consist of two hydrophobic “tails, ” which are fatty acid chains, and one hydrophilic “head, ” which is phosphate group.

Detailed explanation-2: -Hydrophilic head-polar head pointing towards water (water attracting). Hydrophobic tail-nonpolar tail pointing towards dirt (water-repelling).

Detailed explanation-3: -Phospholipids are a class of lipids whose molecule has a hydrophilic “head” containing a phosphate group and two hydrophobic “tails” derived from fatty acids, joined by an alcohol residue (usually a glycerol molecule).

Detailed explanation-4: -Each phospholipid is amphipathic, with two hydrophobic tails and a hydrophilic head. The hydrophobic tails face inward towards one another, and the hydrophilic heads face outwards.

Detailed explanation-5: -A hydrophilic head and two hydrophobic tails comprise this phospholipid molecule. The hydrophilic head group consists of a phosphate-containing group attached to a glycerol molecule. The hydrophobic tails, each containing either a saturated or an unsaturated fatty acid, are long hydrocarbon chains.
