| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

Protein engineering of Saccharomyces cerevisiae oxidosqualene-lanosterol cyclase into parkeol synthase.[Pubmed:23043506]
Org Lett. 2012 Oct 19;14(20):5222-5.
A Saccharomyces cerevisiae oxidosqualene-lanosterol cyclase mutant, ERG7(T384Y/Q450H/V454I), produced Parkeol but not lanosterol as the sole end product. Parkeol undergoes downstream metabolism to generate compounds 9 and 10. In vitro incubation of Parkeol produced a product profile similar to that of the in vivo experiment. In summary, Parkeol undergoes a metabolic pathway similar to that of cycloartenol in yeast but distinct from that of lanosterol in yeast, suggesting that two different metabolic pathways of postoxidosqualene cyclization may exist in S. cerevisiae.
Triterpene alcohol and fatty acid composition of shea nuts from seven African countries.[Pubmed:20513968]
J Oleo Sci. 2010;59(7):351-60.
The content and composition of triterpene alcohol fractions of the non-saponifiable lipids (NSL) along with the fatty acid composition of the kernel fats (n-hexane extracts) of the shea tree (Vitellaria paradoxa; Sapotaceae) were determined for 36 samples from seven sub-Saharan countries: Cote d' Ivoire, Ghana, Nigeria, Cameroun, Chad, Sudan, and Uganda. The fat content of the kernels, proportion of NSL in the fats, and triterpene alcohols in the NSL are in the range of 30-54, 2-12, and 22-72%, respectively. The triterpene alcohol fractions contained alpha-amyrin (1), beta-amyrin (2), lupeol (3), and butyrospermol (4) as the major constituents along with minor or trace amounts of psi-taraxasterol (5), taraxasterol (6), Parkeol (7), 24-methylene-24-dihydroParkeol (8), 24-methylenecycloartanol (9), dammaradienol (10), and 24-methylenedammarenol (11). Fatty acid composition is dominated by stearic (28-56%) and oleic (34-61%) acids. Shea butters from West African provenances contained in general higher levels of triterpene alcohols and stearic acid than those from East African provenances. Both stearic acid and total triterpene alcohol contents were significantly correlated to the latitude and elevation of the source population, indicating that higher levels of these compounds are found at higher ambient temperatures.
