the low pH of about 0,8-1,5 kills all the bacterias except enterics like E.coli.
Bile is secreted by liver and is stored in gall bladder.
Small Intestine
Liver secretes bile juice which is stored in gall bladder. Bile is alkaline and contains salts which help to emulsify fats present in the food.
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.
Liver produces bile. Bile contains bile salts and bile pigments. You have sodium taurocholate and sodium glychocolate as bile salts. These salts reduce the surface tension of the fat globules. Very small particles of the fat are formed. This greatly increase the surface area of the fat. this gives an opportunity to the enzyme to act on the fat granules. Fat is split into fatty acid and glycerol. These products are absorbed through the wall of the intestine.
Bile salts in the intestine
It plays a role in the oxidation of cholesterol into bile salts in the liver. This allows the cholesterol in to be excreted out of the body by changing it into a water soluble form (bile salts).
Bile is 85% water, 10% bile salts , 3% mucus and pigments, 1% fats, and 0.7% inorganic salts , thats mean bile is secretion which lack enzyme.
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.
steroids (bile salts, vitamin D, sex hormones, adrenocortical hormones)
To reclaim bile salts to be recycled back to the liver for resecretion.
every food contains minerals salts except some food miinerals are important for our body
'Bile Duct' or technically the Common Bile Duct is formed by the union of Common Hepatic duct and Cystic Duct. It passes through the head of pancreas and ends in the duodenum. It transports bile salts, bile pigments among others.
Due to large scale misuse of antibiotics by the unqualified doctors, you have landed in the problem of emergence of multi drug resistant bacteria. Now you have to invent the new antibiotics.The bile salts prevent the growth of gram positive bacteria. That is the reason why gram negative bacteria grow in the the intestinal tract. So this chemical can be used by intravenous route to treat the systemic infections by gram positive bacteria. There will be toxic accumulation of this chemical in the body. It is reabsorbed by enterohepatic circulation. So you have to invent the chemical or pair of chemicals, which will do precipitation of the bile salts in the intestine. The efficacy of this remedy has to be tried in clinical practice in case of the multi drug resistant gram positive infections.
