Medchemexpress LLC 7-keto-Deoxycholic acid | 911-40-0 | 99.7% | 406.56 | 5 MG
7-keto-Deoxycholic acid is a metabolite of bile acids found in *Clostridium absonum*. It is also produced from *Lactobacillus* and *Bifidobacterium* under specific conditions. In vitro, its bioconversion rate increases with the addition of an equimolar concentration of deoxycholic acid. It is induced by deoxycholic acid and subsequently metabolized. For example, *E. lentum-like c-25* can convert cholic acid to deoxycholic acid and 7-keto-Deoxycholic acid under anaerobic incubation.
- Metabolite of bile acids.
- Can be converted from *Lactobacillus* and *Bifidobacterium*.
- Available in various quantities.
- High purity.
- Solid appearance, white to off-white color.
- Endogenous metabolite.
- Shipping at room temperature in continental US; storage at 4°C, protected from light.
- Soluble in DMSO.

Sigma Aldrich Fine Chemicals Biosciences p Xylene ReagentPlusR 99
p-Xylene is an isomeric form of xylene. It undergoes friedel-Crafts acylation reaction with various acids in the presence of zeolites (catalyst). It can be obtained from the mixtures of isomeric forms of xylene and ethylbenzene isolated from the naptha fraction of petroleum. Also it can be prepared from toluene by employing ZSM (Zeolite Socony Mobil)-5 catalysts. It is a raw material for the manufacture of PET (poly(ethylene terephthalate)) bottles. Its sustainable synthesis from ethylene and dimethylfuran in the presence of zeolite catalysts has been reported.
Sigma Aldrich Fine Chemicals Biosciences Methanol-OD 99.5 atom D100G
Methan(ol-d) (Methanol-OD CH3OD) is a deuterated form of methanol. Dissociation of CH3OD adsorbed on the clean W(100) surface resulted in the formation of hydrogen carbon and oxygen (-CO). Additionally carbon dioxide water and methyl formate were obtained when similar dissociation was conducted over the W(100)-(5x1)C surface. The dissociation process was monitored by temperature-programmed reaction spectroscopy. Self-diffusion coefficient shear viscosities and densities of liquid CH3OD have been determined by NMR spin-echo technique.
Sigma Aldrich Fine Chemicals Biosciences Methanol-d4 99.8 atom D
Methanol-d4 (CD3OD) is a deuterated NMR solvent useful in NMR-based research and analyses. Absolute infrared absorption intensities of CD3OD have been reported between 8000 and 350cm-1.
