Lipids are made of the elements Carbon Hydrogen and Oxygen.

They have a lower portion of water than carbohydrates and they are insoluble in water - this is because most of their chemical bonds are mostly non-polar.

The funtions of Lipids include:

  • Energy Storage
  • Making up membranes
  • Insulation
  • Protection
  • Boyancy
  • Acting as hormones

Lipids are mode of two molecules: glyrecrol and fatty acids.

A Glycerol molecule is made up from three Carbon atoms with a Hydroxyl Group attached to it and Hydrogen atoms occupying the remaining positions.

The hydroxyl group is a functional group consisting of a hyrogen atom covalently bonded to an oxygen atom.               …
