General description
Bile salt is an organic sodium salt with a conjugate of any of the bile acids along with either glycine or taurine. Biles salts are composed of four different kinds of bile acids - cholic, deoxycholic, chenodeoxycholic and lithocholic acids.Bile salts are extracted under controlled conditions from purified fresh bile, to be used in bacteriological culture media, where it behaves as a selective inhibitory agent that enables isolation and identification of pathogens. For example, in MacConkey Agar/Broth.
Application
Bile salts may be used as one of the selective agents to prevent the growth of injured Escherichia coli cells, in an experiment done in order to identify the specific agent in the selective media which would inhibit the growth of the injured Escherichia coli ML30 cells.[1] It may also be used for identification of isolates of Vibrio (Beneckea) vulnificus which is a halophilic bacterium, found responsible for causing several human infections.[2]

The products B8756, B8631, and B3883 contains bile acids or bile salts conjugated with glicine and taurine?
1 answer-
B8756 - Bile salts - An organic sodium salt with conjugates of any of the bile acids to either glycine or taurine. No information on concentration of the conjugates.
B8631 - Bile extract, porcine - Contains conjugates of hyodeoxycholic acid with glycine or taurine as well as other bile salts. No information on concentration of the conjugates.
B3883 - Bile bovine - Extract from purified fresh bovine bile (which is approximately 70% bile salts). While there is no specification in the description, bile salts are conjugates of bile acid with glycine or taurine. No information on concentration of the conjugates.Helpful?

What is the molecular weight of B8756?
1 answer-
B8756 is composed of four different kinds of bile acids - cholic, deoxycholic, chenodeoxycholic and lithocholic acids. Since this product is a mix of bile salts, there is not a molecular weight for the product. You can use the molecular weight of each component and average it - but that will not allow for accuracy in making molar solutions.

Is it used to mimic the physical and physiological properties of bile ?
1 answer-
Yes, bile salts can be used to mimic the physical and physiological conditions of bile in certain applications, but does not reflect the full panel of Bile components. Bile is typically composed of 0.7% bile salts, 0.2% bilirubin, 0.51% fats (cholesterol, fatty acids, and lecithin), and 200 meq/L inorganic salts.
