Document Summary
Lipids are also biological molecules but not macromolecules- monomers: fatty acids and glycerols. Functions of these biological molecules are related to their shape and the chemical properties of their monomers. Some roles include: energy storage, structural support, etc. The energy currency of the cell (source of usable energy) which has a nucleotide and triple phosphate group when one p is removed by being hydrolyzed and creates energy. Linked by weak van der waals forces (nonpolar forces that don"t like to interact with water) Can be used for: energy storage, cell membrane s, to capture light energy, hormones and vitamins, thermal insulation, electrical insulation of nerves. Lipid a because there is a hydrophobic and hydrophilic end. It"s a saturated fatty acid and is amphipathic since the polar region can interact with water. Lipid b looks like a triglyceride and will not work. Lipid c is a phospholipid and creates most cell membranes so yes, it will work.
