A phosphoglyceride is always made up of:
a saturated or unsaturated fatty acid esterified to a phosphate group which is also attached to a glycerol molecule
only a saturated fatty acid esterified to a glycerol molecule to which a phosphate group is also attached
only an unsaturated fatty acid esterified to a glycerol molecule to which a phosphate group is also attached
a saturated or unsaturated fatty acid esterified to a glycerol molecule to which a phosphate group is also attached
As discussed in
Hydrolases -
Enzymes catalyzing hydrolysis of ester, ether, peptide, glycosidic , C-C, C-halide or P-N bonds
-
Fatty acids are esterified with glycerol. Fatty acids can be saturated or unsaturated
Option 1)
a saturated or unsaturated fatty acid esterified to a phosphate group which is also attached to a glycerol molecule
This is incorrect option
Option 2)
only a saturated fatty acid esterified to a glycerol molecule to which a phosphate group is also attached
This is incorrect option
Option 3)
only an unsaturated fatty acid esterified to a glycerol molecule to which a phosphate group is also attached
This is incorrect option
Option 4)
a saturated or unsaturated fatty acid esterified to a glycerol molecule to which a phosphate group is also attached
This is correct option
