ANSWER IN SHORT,
(7-9 LINES ANSWER).

Answer 1

The key issue in the digestion and absorption of fats is one of solubility: lipids are hydrophobic, and thus are poorly soluble in the aqueous environment of the digestive tract.  

The digestive enzyme, pancreatic lipase, is water soluble and can only work at the surface of fat globules.  

Digestion is greatly aided by emulsification, the breaking up of fat globules into much smaller emulsion droplets.

Bile salts and phospholipids are amphipathic molecules that are present in the bile.

Motility in the small intestine breaks fat globules apart into small droplets that are coated with bile salts and phospholipids, preventing the emulsion droplets from re-associating.  

The emulsion droplets are where digestion occurs.

Emulsification greatly increases the surface area where water-soluble pancreatic lipase can work to digest TAG.

Another factor that helps is colipase, an amphipathic protein that binds and anchors pancreatic lipase at the surface of the emulsion droplet.

Answer 2

Fats gets converted into Small globules and Digested in stomach with the help of BILE JUICE.

This process is called EMULSIFICATION.

It is Secreted by Liver into Duodenum and Bile is the only substance which didn't contain any Enzymes.

Also,
The enzymes like TRYPSIN and LIPASE also acts upon fats and converts them into FATTY ACIDS AND GLYCEROL
