bile salts in bile speed up fat digestion
The answer is bile salts. You have sodium taurocholate and sodium glaucocholate as bile salts. They do emulsification of the fat. That helps in fat digestion.
the bile converts larger molecules of fat into emulsified fat by a process called emulsification
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.
bile salts emulsify fats and solubilize them ,thus the are absorbed.Bile salt is completely necessary for digestion in the body. They help to break down the fat in our body that otherwise could not be digested. The bile salts help to break down the fat molecules into smaller parts, and they are then easily digestible by the small and large intestine.After the bile salts are done doing their job, they are returned back to the liver and recycled, and are used again when they are needed. Bile salts are basically sodium based salts that are all derived from the liver.
Bile aids in the chemical digestion of fat. The lipids and salts found in bile help break fats into smaller pieces while enzymes can more easily break down fat molecules.
Bile is produced in the liver and helps to digest fat in the human body. Once produced, bile is stored in the gallbladder and is discharged into the duodenum when a person eats.
Bile salts break down fats into very small particles so that the lipases (fat enzymes) have a lot of surface area to work on. If the gall bladder is removed, this function is reduced and the fats are passed through without being digested.You have bile salts called as sodium taurocholate and sodium glycocholate. They are secreted by the liver in the bile. They act as the agents, which emulsify the fat. That means the fat is broken down to very small spherical particles. This greatly increase the surface area of contact between the lipase enzyme and fat. This helps in digestion of the fat. The bile salts are reabsorbed in lower part of the intestine. So the bile salts are recycled. This process is called as 'Enterohepatic' circulation.
fat
Fat is digested in small intestine. As Fat does not mix with water, large Fat globules are there and such they can not be digested by the pancreatic enzyme called 'Lipase' in short time. For that 'Nature' has evolved a very good solution. Bile salts are released by gall bladder under hormone released, called as 'Cholecystokinin'. Bile contains bile pigments to be excreted in the intestine and bile salts 1) Sodium taurocholate and 2) Sodiumglaucocolate. Both of them reduces the surfacetensionin the intestine. So that Fat becomes split into very small size particles called as 'chylomicron'. This increases the surface area of the fat globules to very large extent. There by digestion of Fat becomes much easy. In the distal part of intestine bile salts are reabsorbed to be released for next digestion. This is called as 'enter o- hepatic' circulation.
Micelles (My-cells) : tiny spherical complexes of emulsified fat that arise during digestion; most contain bile salts and the products of lipid digestion, including fatty acids, monoglycerides, and cholesterol.
The pancreatic extracts hydrolyze fat in presence of bile. The enzyme lipase in pancreas hydrolyzes fat when there are bile salts.
