Question:
Which of the following describes lipids?
A. A source of nutrients for organisms
B. Energy-storage molecules
C. Molecules having structural role in membranes
D. Molecules that are part of hormones and pigments
E. All of the above
Lipids
Biological lipids are a diverse group of chemicals which are either completely or poorly soluble in water. These are known to be soluble in non-polar solvents such as ether, chloroform and benzene. Lipids are not polymers and their hydrophobic nature is due to the predominance of hydrocarbon chain.
