Question

Lecithin is phospholipid its main component(s) is/are?

• A. Glycerol $+$ $2$ Fatty acids $+$ $H_{3}P{O}_4$ $+$ Choline
• B. Glycerol $+$ $H_{2}P{O}_4$ $+$ Choline
• C. Glycerol $+$ $3$ fatty acids
• D. Only Glycerol

Answer 1

The correct option is A Glycerol $+$ $2$ Fatty acids $+$ $H_{3}P{O}_4$ $+$ Choline

• Lecithin is a phospholipid present in the plasma membrane. It is composed of phosphoric acid, choline, two fatty acids, and esters of glycerol.
• The chain length, position, and degree of unsaturation of these fatty acids vary and this variation results in different lecithins, which represent different biological functions.
