Expert Answer:

Butter is produced from milk or milk products, and contains no less than 80 per cent milk fat. Commercial butter contains 80 to 82 per cent fat, which is of animal origin, 14 to 16 per cent moisture and 0 to 4 per cent salt.

So digestion of butter follows the pathway of digestion of fats or lipids in the body.

Bile helps in emulsification of fats, i.e.,

breaking down of the fats into very small micelles. Bile also activates lipases.

Lipases are present in pancreatic juice and intestinal juice.

 

Fats are broken down by lipases with the help of bile into di-and

monoglycerides.

Fats  ----> Diglycerides    ----------> Monoglycerides

 

Di and Monoglycerides -----------à  Fatty acids+Glycerol. (by action of lipases)

 

Fatty acids and glycerol being insoluble, cannot be absorbed into the

blood. They are first incorporated into small droplets called micelles which

move into the intestinal mucosa. They are re-formed into very small protein

coated fat globules called the chylomicrons which are transported into

the lymph vessels (lacteals) in the villi. These lymph vessels ultimately

release the absorbed substances into the blood stream.
