Starch is a carbohydrate and does not directly break down fat. However, when you consume starch, your body converts it into glucose for energy. If you consume more starch (calories) than your body needs, the excess glucose can be stored as fat.
The name is bile salts and help to break down fat in food. It doesn't actually break it down, it makes the fat particles much smaller so that the fat enzymes can work faster.
Chemical digestion
Bile helps digest fatty foods by emulsifying the fats.
The liver helps to break down fats by producing bile.
Fatty acids and glycerol
It was able to break down the fat into fat droplets!
Bile, which is produced by the liver and stored in the gallbladder, breaks up fat particles in the digestive system. The bile salts in bile act as emulsifiers to break down fats into smaller droplets, making it easier for enzymes to further break them down for digestion.
Bile makes large fat molecules into very small one and that allows the enzyme lipase to further break down fat. It doesn't matter if it is pigs or humans.
Fat breaks into fatty acids and glycerol by the action of lipase in the small intestine.
Lipase enzymes digest fats (otherwise known as 'lipids'). Lipids are broken down into fatty acids and glycerol.
No bile does not break down fat. Bile salts only aid in digestion of lipids(fats) by emulsifying them. Pancreatic lipase breaks down the lipids.
