Comparative studies of 'bile salts'; preliminary survey.

Metabolism of Trihydroxycoprostanic Acid: Formation from Cholesterol in the Alligator and Conversion to Cholic Acid and Carbon Dioxide in Vitro by Rat Liver Mitochondrias

Comparative studies of bile salts (l-3) indicate that the evolution of these substances may have proceeded through a stage marked by the occurrence of C-27 acids such as trihydroxycoprostanic acid. This steroid acid, found in the bile of crocodylidae and other “primitive” vertebrates, is also important from a metabolic standpoint, since it may be an intermediate in the formation of mammalian bi...

Comparative studies on 'bile salts'. 17. A bile alcohol from Chimaera monstrosa.

Comparative studies of bile salts. 10. Bile salts of the King penguin, Aptenodites patagonica.

no glycine conjugates in the bile salts of eight species of birds, and Wiggins (1955a), in a careful examination of chicken bile by countercurrent distribution methods, failed to find either free bile acids or glycine conjugates. The present report is of an examination of the bile salts of the King penguin, Aptenodites patagonica, and includes remarks on the chemical nature of tetrahydroxynorst...

Suitability of MRS-bile Agar for the Selective Enumeration of Mixed Probiotic Bacteria in Presence of Mesophilic Lactic Acid Cultures and Yoghurt Bacteria

Measuring the viability of probiotic microorganisms in food products using plate count methodology is a common practice due to the simplicity (ease of performance), inexpensive and routine testing characters ofthis method. In present study, the suitability of de man rogosa and sharpe agar (MRS) bile agar medium forthe selective enumeration of mixed probiotic bacteria (Lactobacillus ...

Comparative studies of bile salts. Bile salts of the lamprey Petromyzon marinus L.

1. Bile salts of Petromyzon marinus L. ammocoetes appeared to consist solely or chiefly of a crystalline substance, whose chromatographic and i.r.-spectral characteristics suggested that it was a monosulphate ester of a bile alcohol having the 3alpha,7alpha,12alpha-trihydroxy pattern of substitution in a 5alpha-steroid nucleus. 2. This substance on cleavage with dioxan-trichloroacetic acid gave...
