what is the role of waxes
Lipids also exist in the form of waxes. Waxes are similar to other lipids like fats and oils but differ in the fact that waxes are, esters of higher fatty acids with long chain alcohols (i.e. not with glycerol).(5). A major property of wax is that it is waterproof and is therefore used by plants on their leaves (the waxy cuticle).
