Table 4. Fatty acid distribution in individual phospholipid classes in the yeast plasma membrane.
Relative proportion of the major phospholipid classes PC (phosphatidylcholine), PE (phosphatidylethanolamine), PI and PS (phosphatidylserine) in isolated yeast plasma membrane fractions. Relative abundance of fatty acids are given as mol % of the total. Values represent means±S.D. for three independent determinations. nd, not detected.
