Carbohydrates have many polar #"OH"# groups. Lipids consist largely of nonpolar hydrocarbon chains.



A typical carbohydrate is glucose, #"C"_6"H"_12"O"_6 #.

Most carbohydrates are hydrophilic and soluble in water because of their polar #"OH"# groups.


Lipids are hydrophobic and insoluble in water.

They have varied structures, but all have a polar "head" and a large nonpolar "tail"".

Fats and oils are typical lipids.

The structure of a typical fat is

The molecule is mostly nonpolar hydrocarbon with some polar #"C=O"# groups at one end.
