they both contain phosphate groups

they are both important cell signaling molecules

they are both important energy sources

they are both important for all cell structure

Respuesta :

Answer:

they both contain phosphate groups

Explanation:

A nucleic acid has a phosphate molecule at 5’ Carbon. This phosphate bonds with the 1’ Carbon of the next nucleic acid forming a phospho-diester bond. A phospholipid, as the name suggests, also comprises of a phosphate molecule that makes the hydrophilic end of the molecule. Attached to the phosphate molecule is a glycerol molecule and two fatty acid chains (the hydrophobic end of the molecule). Phospholipids are usually amphipathic and are significant components of the cell membrane.
