Questions: The complete hydrolysis of one mole of phosphatidylserine yields the components phosphate, serine, fatty acid and glycerol, in which of the following respective molar ratios? a) 2: 1: 1: 1 b) 1: 2: 1: 2 c) 1: 2: 1: 1 d) 1: 1: 2: 1

Solution Steps

Phosphatidylserine is a phospholipid that consists of a glycerol backbone, two fatty acid chains, a phosphate group, and a serine molecule.

When phosphatidylserine undergoes complete hydrolysis, it breaks down into its constituent components:

• One phosphate group
• One serine molecule
• Two fatty acid molecules
• One glycerol molecule

From the hydrolysis, we get:

• 1 mole of phosphate
• 1 mole of serine
• 2 moles of fatty acids
• 1 mole of glycerol

Thus, the molar ratio of phosphate:serine:fatty acid:glycerol is \(1:1:2:1\).
