Lipids are molecules that are not soluble in water

but can be dissolved in non-polar substances such

as alcohol or chloroform (Mandal, n.d.).

Lipid molecules are stored in adipose, or fat tissue,

and can be broken down in our bodies to form an

energy called ATP. To do so, the lipid molecule is

dissected into its base pieces, glycerol and fatty

acids. Each of the fatty acids is then broken down

into two-carbon pieces and acetyl CoA is formed

from each carbon piece. Each acetyl CoA molecule

enters into a series of chemical reactions called the

citric acid cycle and ultimately produces 12 ATP

(Hudon-Miller, 2013).

fatty acids:
