Explain the role of bile salts during fat digestion.?

Question

this biochemical processes experiment

Answer 1

Bile salts are fluids secreted by the liver and sent to the duodenum where it aids in the emulsification of fats. Bile acts as an emulsifying agent in the digestive tract by dispersing ingested fats into small globules Sorry, that is all I know. Hope it is some help

Answer 2

There are two different types of gallstones, cholesterol and pigment. Scientists believe cholesterol stones form when bile contains too much cholesterol, too much bilirubin, or not enough bile salts, or when the gallbladder does not empty completely or often enough. The reason these imbalances occur is not known. The cause of pigment stones is not fully understood. The stones tend to develop in people who have liver cirrhosis, biliary tract infections, or hereditary blood disorders—such as sickle cell anemia—in which the liver makes too much bilirubin. Bilirubin is produced by the liver as waste when it breaks down old red blood cells. It it then mixed in with the gall to be eliminated in the feces, and is the reason normal stools are brown. Cholesterol of course is produced by the body to a certain extent, as a means of transporting fat for storage, or retrieving it for conversion into energy. Oxidizing cholesterol produces bile salts, which are a type of steroid acid. That is added to the gallbladder as well, and in the small intestine, bile salts help break down fats for digestion, regular salt, and binds with fat soluble vitamins so the body can use them. If too much cholesterol, bile salts or bilirubin are produced and stored in the gallbladder, or if for some reason the gallbladder isn't emptied often enough, the chemicals can bind together to form stones. Unfortunately, nobody is really sure why some folks get them and some don't. They know women are more prone to them, Native Indians and Mexicans as well are at higher risk. Of course diet plays a part, since a high fat diet means you are likely eating a lot of fat and not much fiber- so you'd have higher cholesterol as well. And a history of crash diets is risky as well. Exteme diets and a large weight loss mean a lot of fat was metabolized in the process- meaning a lot of cholesterol got handled and excreted in the bile. And odd as it sounds, people with high cholesterol who take cholesterol lowering drugs will often develop them as well, a result of the larger amount of cholesterol again being broken down and excreted. The trouble is, none of these things mean you will automatically develop gallstones. Just that folks who do develop them usually have at least one of these factors in common. Gallstones are really a symptom of something in the metabolic process of the liver being upset and out of balance. It's not all easy to explain, and it's not just the diet. Skinny white men shouldn't get gallstones if that were the case, and though they don't often, sometimes they do. And not all overweight American Indian women get them, although many do. So diet and weight alone don't explain it. Even the cholesterol problems won't explain it. Not everyone with high cholesterol develops gallstones, and not everyone with gallstones has high cholesterol levels. You are right in that a diet of fatty foods raises the risk, but unfortunately that is only one part of the equation. And science is still working on the other parts. At least we can control some factors, like our weight and diets. The rest, well- you have to break down old red blood cells, because they just won't live forever and need to be replaced. You have to produce a certain amount of cholesterol, because your body has to have some way to transport fat to and from storage. Fat molecules themselves are a little too inefficient and too different between the various kinds of fats. And you have to produce bile salts, so you can digest fat to begin with, and to be able to absorb the fat soluble nutrients in your food so your body can use them. So you see it is a lot more complex than you might think. But it was a good question, and shows a lot more thought than most folks give the matter. Unfortunately most folks don't think about stones, gallbladders or livers, or any of the rest of that stuff until they have a problem. Then they really don't care how it happened, they just want the things fixed. Of course, once you take the gallbladder out, it can't happen again, and they don't have a reason to care. It's just another example of how wonderfully and intricate the function of the body really is. Who knew old blood cells made poo brown?
