my question is state two biological function of lipid in cell or organism. can i choose the function of cholesterol in body? and it is cholesterol are made up of lipid?

Dear Student , Yes you can choose the function of cholesterol in body and cholesterol is actually part lipid, part protein. This is why the different kinds of cholesterol are called lipoproteins. cholesterol is only minimally soluble in water, or hydrophilic. Because of this, it dissolves in blood at exceedingly small concentrations. Regards!
