Which macromolecules are waxy or oily? Carbohydrates, lipids, proteins, nucleic acids?

Question

I need help with my homework. And I can't find out which are waxy or oily. Please help!

Answer 1

Of the choices you give, Lipids would be most likely to be waxy or oily because they have long hydrocarbon tails on a polar head.  Paraffins are 100% carbon and hydrogen chains (like lipid tails).  At room temperature they are liquids between 4 and 8 carbons in the chain.  From about 9 carbons up, they are solid at room temp and are waxy.  The longer the chain, the harder and dryer the wax is.  

Answer 2

Lipids

True wax is a long hydrocarbon chain, like paraffin.

Lipids have chains of hydrocarbon on them.

(Hydrocarbon is different from carbohydrate, the hydrocarbon is just CH but the carbohydrate is CHO)

Answer 3

lipids
