lipids are essentially fat. there aren't many polar bonds, if any.
fatty acids have an acid at the end. that makes them slightly more polar.
sugars have OH groups. That makes them especially polar because of the potential of hydrogen bonding in water. That's part of the reason sugar dissolves in water.
With the last two, the general structure of an amino acid
R
|
H2N-C-COOH
|
H
[the bonds are all on the central carbon. it shows it like this under the modification but not on the preview]
where R can be a nonpolar side chain (making it hydrophobic) or it can be polar.
With all of these groups, depending on the side chain or the length of the molecule, the ratio varies.

Lipid. They are mostly all C-H bonds

hydrocarbone
