Role of bile and lipase in fat digestion

[PRINCESS NOOR]

Dear Sirs,

i would like to now exactly the role of these two substances in the process of fat digestion.

1. bile
2.lipase

thank you for this lovely site, and i appreciate your kindness and generous to answer me this simple question which confused me a lot.

with my regards

For Lipase,
This is trick for the future. Any biological compount that finishes by "ase" is always an enzyme. The first portion of the name is descriptive of the function or taget of the enzyme. So lipids are degraded by an enzyme. So lipases break down neutral fats (triglycerides) into glycerol and fatty acids

For bile, it aids in the digestion and absorption of fats in the intestines and stimulates peristalsis. The role of bile is to break down fat into smaller units so lipases can degraded it.

For #1, see http://arbl.cvmbs.colostate.edu/hbooks/pathphys/digestion/smallgut/absorb_lipids.html for a definition and a good explanation of the process of digesting lipids, since it seems you have a number of questions on this.

For #2, there's a good mnemonic...Arteries lead Away from the heart. Veins then return blood to the heart.
