The Phosphatidylcholine Molecule - 3D

Phosphatidylcholine is a phospholipid that is a major constituent of cell membranes. Phospholipids consist of a water-soluble head (a positively charged (polar) group), linked to two water-insoluble nonpolar tails (by a negatively charged phosphate group). Both tails consist of a fatty acid, each 14-24 carbon groups long. Read more
