Q.First step in digestion of fat is
a. Emulsification
b. Enzyme action
c. Absorption by lacteals
d. Storage in adipose tissue

Fat digestion depends heavily on bile, even though bile itself contains no enzymes: bile salts emulsify large fat droplets into many smaller globules, dramatically increasing the surface area available for enzyme action, and also activate the lipase enzymes. Pancreatic lipase and intestinal lipase then act on this emulsified fat (mainly triglycerides), hydrolysing it first into free fatty acids and monoglycerides, with the monoglycerides further broken down into fatty acids and glycerol. Because fatty acids, glycerol and fat-soluble vitamins are not water-soluble, they are packaged into tiny micelles for absorption i …
