WebPhospholipids are amphiphilic molecules with hydrophobic fatty acid chains and hydrophilic moieties. They occur naturally in all living organisms as the major components of cell membranes. Various phospholipid classes with different polar moieties are found in nature. pH greatly affects the association of the polar moieties in phospholipids. WebThis phospholipid molecule is composed of a hydrophilic head and two hydrophobic tails. 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.

"WebPhospholipids have both hydrophobic and hydrophilic regions in a single molecule. The phosphate head group is hydrophilic because it is polar, enabling it to form hydrogen bonds with water. IN CONTRAST, the two long fatty acid tails are hydrophobic because they are nonpolar and do not form hydrogen bonds with water. " - Phosphate head – hydrophobic

Phospholipid Structure & Function What is a Phospholipid?

WebThe hydrophilic heads of phospholipids in a membrane bilayer face outward, contacting the aqueous (watery) fluid both inside and outside the cell. Since water is a polar molecule, it readily forms electrostatic (charge-based) interactions with the phospholipid heads.
