Which type of phospholipids is more permeable to glycerol

Phospholipids derived from glycerol are called phosphoglycerides.

Lipid-soluble molecules can readily pass through a lipid bilayer. Surprisingly, some small polar molecules are capable of permeating the lipid bilayer without the aid of a membrane transport protein. Examples include water (H2O), glycerol (C3H5(OH)3), urea (CH4N2O), and ethanol (C2H6O).

Phospholipids are amphiphilic lipids consisting of a glycerol backbone or an amino-alcohol sphingosine backbone, which is esterified to one or two fatty acids, a phosphate group, and a hydrophilic residue.

answer; (phospholipid);

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
