Study group discussion: What does emulsification mean in fat digestion

What does term emulsify mean in fat digestion?

Breakage of large fat globules into small ones by bile is called emulsification of fat.

Making the fat to be smaller particles, helps it mix in with the water. Eg. Milk is an emulsion of fat and water.

Yes.. just to make it easier to be digested and absorbed.

Like fat broken down into glycerol and fatty acid? Am I right?

Not really fat into glycerol and fatty acid. More to fat droplets mixing with bile. It increases the surface area to volume ratio.

More surface area : more sites for lipase to bind and digest

Thank you, guys!
