No. Bile is a digestive fluid stored in the gallbladder, containing water, electrolytes, bile acids, cholesterol, and bilirubin. Bile acids are specific steroid molecules within bile that perform the key digestive function.
Yes. Elevated levels of bile acids in the blood (cholestasis) or their malabsorption in the intestine can cause symptoms like itching, diarrhea, and nutrient deficiencies.
They are a class of drugs (e.g., cholestyramine) that bind bile acids in the intestine, preventing their reabsorption. This forces the liver to use more cholesterol to make new bile acids, thereby lowering blood cholesterol levels.
Despite the name, in the body they are often found as salts (bile salts) conjugated with amino acids, which makes them effective at neutral to slightly alkaline pH in the small intestine.
