Answer 1

The correct option is D Cell membrane

Sialic acid is a constituent of the cell membrane. It acts as a cell receptor. It is a monosaccharide with a nine-carbon atom. It helps to keep water on the surface of the cell as it provides the negative charge to the membrane which attracts positively charged water molecules. It helps in the uptake of cellular fluid.

So, the correct answer is option D.
