lipid
Water-repelling compound
A lipid is any of a class of organic compounds that are fatty, waxy, or oily—substances that dissolve in organic solvents but not in water.
Fats, oils, cholesterol, and cell membranes are all lipids.
The term appears most often in scientific and medical contexts: blood lipid levels, lipid metabolism.
