Yes, of course.
mostly covalent bonds as lipids are organic molecules
High degree of unsaturated bonds
Lipids are held together by non polar bonds but also have a few polar bonds between carbon and oxygen. But because the rest of a lipid molecule is nonpolar this contributes little to physical properties.
The difference is related to which long chain fatty acid is incorporated. If it is a fatty acid that has double bonds, then it is an unsaturated lipid. If it contains fatty acids that have no double bonds, then it is a saturated lipid.
Amino acids from proteins.
unsaturated
No, peptide bonds are between amino acids in proteins.

No. Long chains of hydrocarbons, basically what lipids are, store much more energy in the bonds than carbohydrates do.
The type of chemical bonds for lipids are nonpolar C-H bonds. The actual bonds that attach the fatty acids to the glycerol are refered to as ester linkages

If there are no double bonds, then carbon will take up as many hydrogens as it can, two (three on the ends). Because there are more hydrogens bonded, they are referred to as "saturated" lipids. Unsaturated lipids have double bonds between the carbons and hydrogens. When there is a double bond, one carbon only bonds with one hydrogen - "unsaturated" lipids. The double bonds cause "kinks" in the fatty acid tails, so it is more difficult to "pack" them together. For this reason, they do not solidify at room temperature. However, saturated lipids may solidify at room temperature -- this is how you distinguish between saturated and unsaturated lipids by sight. Examples of saturated lipids (having no double bonds between carbons and hydrogens) are animal fats. "Saturated fats" is a synonym for animal fat on nutritional labels.
