Vedclass · Answer

(D) Lecithin is a phospholipid,specifically a phosphatidylcholine. Its chemical structure consists of a glycerol backbone,two fatty acid chains,a phosphate group,and a choline molecule. The chemical formula for lecithin is $C_{42}H_{82}NO_8P$. Analyzing the elements present: $C$ (Carbon),$H$ (Hydrogen),$N$ (Nitrogen),$O$ (Oxygen),and $P$ (Phosphorus) are all present. Sulfur $(S)$ is not a component of the lecithin molecule. Therefore,the correct option is $D$.
