Medchemexpress LLC 7-keto-Deoxycholic acid | 911-40-0 | 99.7% | 406.56 | 50 MG
7-keto-Deoxycholic acid is a metabolite of bile acids found in *Clostridium absonum*. It can also be converted from *Lactobacillus* and *Bifidobacterium* under specific conditions. It shows an increasing bioconversion rate with the addition of an equimolar concentration of deoxycholic acid and is induced by deoxycholic acid and then metabolized. *E. lentum*-like c-25 converts 81.7% of 2 mM cholic acid to deoxycholic acid and 3.7% to 7-keto-Deoxycholic acid under anaerobic incubation. *E. lentum*-like c-25 also converts 91.5% of 150 mg/mL cholic acid to deoxycholic acid and 1.1% to 7-keto-Deoxycholic acid under anaerobic incubation.

Medchemexpress LLC Calcifediol-d6 monohydrate (25-hydroxy Vitamin D3-d6 monohydrate) | 2483831-70-3 | 97.5% | 424.69 | 1 MG
Calcifediol-d6 monohydrate is a deuterium-labeled version of Calcifediol monohydrate. Calcifediol monohydrate (25-hydroxy Vitamin D3 monohydrate) acts as an effective VDR ligand and a Vitamin D supplement. It functions as a prohormone within the vitamin D endocrine system (VDES) and undergoes hydroxylation in the liver to form calcitriol, its active counterpart. Calcifediol is known for its ability to rapidly elevate serum Vitamin D levels.
- Can be used as a tracer in research.
- Serves as an internal standard for quantitative analysis using techniques such as NMR, GC-MS, or LC-MS.
- Deuterium labeling is valuable for quantitation during drug development and can influence pharmacokinetic and metabolic profiles.
