TLDR
In this paper, the new phases OV-1 and OV17 were compared with QF-1 in the gas chromatographic analysis of 80 methyl 5β- and 5α-cholanoates and their complete trimethylsilyl (TMSi) ethers.About:

Developmental changes in the composition and function of sarcoplasmic reticulum.
TL;DR: Observations are consistent with nearly all possible mechanisms of membrane assembly and may suggest that the phospholipid-rich membranes of embryonic muscle are gradually converted during development into calcium-transporting structures by stepwise insertion of the ATPase enzyme and other components of the transport system.
Journal ArticleDOI
Metabolism of lithocholate in healthy man. II. Enterohepatic circulation.
TL;DR: It is indicated that considerable lithocholate is absorbed from the distal intestine in healthy subjects but efficient sulfation results in rapid fecal excretion, so that the total lithocholic pool remains small.

Identification of new steranes, terpanes, and branched paraffins in Green River shale by combined capillary gas chromatography and mass spectrometry
Journal ArticleDOI
Isolation and characterization of thirteen intestinal microorganisms capable of 7 alpha-dehydroxylating bile acids.
TL;DR: Strain HD-17, still unidentified, had both activities, but was unique in that it exclusively 7alpha-dehydroxylated cholic acid while biotransforming chenodeoxycholic acid, preferably though 7 alpha- dehydrogenation.

TL;DR: This experiment indicated the stability of bile acid structure during intestinal transit and provided additional evidence for the completeness of the described method of determining fecal bile acids.

TL;DR: The principal bile acids found in the feces of rats fed a standard semisynthetic diet were tentatively identified as deoxycholic, hyodeoxycholics, lithocholic, and 12 ketolithocholic and the daily excretion by adult male rats was 0.57, 1.00, 0.33, and 0.27 mg, respectively.

Identification of mono- and dihydroxy bile acids in human feces by gas-liquid chromatography and mass spectrometry.
TL;DR: The mono- and disubstituted cholanoic acids present in human feces have been investigated and evidence was obtained for the presence of two bile acids having at least one hydroxyl group at a carbon atom other than C(3), C(7), or C(12).

TL;DR: It has been demonstrated that, in spite of the omission of the usual purification steps, the method is specific for bile acids.
