A patient is admitted to the hospital v severe abdominal pain. A scan reveals that the gall bladder has actually multiple stones in it, and one is impede the cystic duct.

You are watching: Explain the importance of emulsification in lipid digestion


Explanation:

The bitterly bladder is important because of the storage and release the bile throughout digestion. Bile is essential in the emulsification (or break up) the nonpolar fats in the aqueous small intestinal fluid. Cystic duct obstruction would an outcome in bile gift unable to reach the little intestine, and also triglycerides would be unable to be properly emulsified and absorbed.


Explanation:

The liver to produce bile, i beg your pardon travels down the bile duct to it is in released into the little intestine, particularly the duodenum. Once the duct is no open, bile backs up and also gets save on computer in the bitterly bladder. When the duct is open, when the tiny intestine senses the existence of food, the bitterly bladder will release the bile come emulsify fats during digestion.


Explanation:

Both bile salts and also phospholipids room excreted native the bile duct right into the upper small intestine (duodenum) come emulsify lipids. They space both amphipathic molecules, which way they have actually non-polar/lipophilic end that can bind come lipids and also polar/hydrophilic end that deserve to bind to water, thus emulsifying the lipids the they contact.

As these compounds room excreted from a single duct, small intestine motility permits them to mix with the components of the little intestine and also emulsify more lipids than they would be able to in a tho environment. Tiny intestine motility additionally helps to rest up large globules of diet fat.

Once emulsified, diet fat have the right to be damaged down through lipase, however lipase itself does not boost emulsification.

Example inquiry #4 : expertise Emulsification


Which body organ stores the compound responsible because that emulsifying lipids throughout digestion?


Possible Answers:

Gall bladder


Liver


Small intestine


Pancreas


Correct answer:

Gall bladder


Explanation:

Fats are typically composed that nonpolar lipids, making castle hydrophobic and insoluble. In order to digest fats, they need to be grouped with each other to increase their surface area and allow for enzyme interaction, digestion, and also absorption.

Fat emulsification is the process of increasing the surface area of fats in the little intestine by grouping them into tiny clusters. This is the duty of bile, a liquid produced by the liver and also stored in the gallbladder. Actual cradle of the fat is then achieved by lipase, an enzyme native the pancreas. Spend lipids space then transported right into the lacteals the the microvilli because that transportation through the lymphatic system before entering the blood.

Example concern #5 : knowledge Emulsification


Bile is created in the __________, save on computer in the __________, and released right into the __________.


Possible Answers:

liver . . . gallbladder . . . large intestine


liver . . . Gallbladder . . . small intestine


kidneys . . . gallbladder . . . small intestine


gallbladder . . . gallbladder . . . small intestine


Correct answer:

liver . . . Gallbladder . . . small intestine


Explanation:

The liver is responsible for synthesizing bile salts; this salts are transferred into the gallbladder as bile. The gallbladder stores bile, i beg your pardon it then secretes into the tiny intestine. Bile contributes to cradle by breaking up huge fat globules, a procedure known as emulsification. Fats room insoluble in water, for this reason emulsification provides pancreatic lipase with an ext surface area ~ above which come act. 

Neither the spleen no one the large intestine are relevant answers to this sentence. The large intestine helps remove undigested waste indigenous the body, absorbs water from waste, and produces/absorbs vitamins (due to nests of useful bacteria that live in the large intestine). The spleen is an organ responsible because that filtering the blood and also housing white blood cells; the is not connected in digestion.

Example question #6 : understanding Emulsification


Bile salts space amphipathic and also essential because that fat absorption. Which of the complying with nutrients will be difficult to absorb in a patient v an i can not qualify to secrete bile salts into the stomach?

I. Vitamin A

II. Vitamin B

III. Vitamin C


Possible Answers:

I only


II only


I and II


All the these


I and III


Correct answer:

I only


Explanation:

Bile salt emulsifies fat into chylomicrons to permit for absorption. The the choices, only vitamin A is fat-soluble. Vitamins B and also C space both water-soluble.

Example concern #7 : knowledge Emulsification


Bile salts emulsify dietary fat by breaking them down right into smaller clusters and also creating a molecule called a __________.


Possible Answers:

globule 


chylomicron


cluster


bolus


micelle


Correct answer:

micelle


Explanation:

Bile salt surround fat droplets in stimulate to develop micelles. This micelles are more accessible to the enzyme that have actually the capacity to break them under further. Chylomicrons space lipoproteins the are crucial in transport and metabolism of lipids.

Example concern #8 : expertise Emulsification


Bile salts make fat droplets more accessible to the enzyme __________.

Possible Answers:

trypsin


chymotrypsin


pancreatic lipase


pepsin


lingual lipase


Correct answer:

pancreatic lipase


Explanation:

Once big fat swarm are damaged down by bile salt to come to be smaller micelles, pancreatic lipase has much more surface area to accessibility fats. The enzymes room able to with the fat droplet through the gaps between bile salts. Fats space not emulsified by bile however in the mouth, so lingual lipase plot upstream that bile to hydrolize long chain hydrocarbons. The other answer options are proteases.
