Which of the following is a major class of lipid? Check all that apply.sphingolipidswaxesglyceridessaturated fatty acidsNone of the above

The major classes of lipids include:

1. Sphingolipids: These are a complex class of lipids that play important roles in signal transmission and cell recognition.

2. Waxes: These are a type of lipid that are very hydrophobic and are often used by plants and animals for protection.

3. Glycerides: These are a type of lipid that includes fats and oils. They are made up of glycerol and fatty acids.

4. Saturated fatty acids: These are a type of fatty acid that have no double bonds between the carbon atoms. They are a type of lipid, but not a major class in and of themselves.

So, the correct answers are sphingolipids, waxes, and glycerides.
