A phosphoglyceride is always made up of
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
a saturated or unsaturated fatty acid esterified to a phosphate group, which is also attached to a glycerol molecule
C.
a saturated or unsaturated fatty acid esterified to a glycerol molecule to which a phosphate group is also attached
Phosphoglycerides are esters of two fatty acids, phosphoric acid and a trifunctional alcohal glycerol.
A fat is formed of two kinds of smaller molecules, i.e., glycerol and fatty acids. Fatty acid molecules join together to glycerol by an ester linkage. A fatty acid has a long carbon skeleton, usually 16 or 18 carbon atoms in length. It there are no double bonds between carbon atoms composing the chain, then as many hydrogen atoms as possible are bonded to the carbon skeleton. Hence, this is known as saturated fatty acids. Unsaturated fatty acid has one or more double bonds.
