别名:2β,6α-二甲基二环[4.4.0]癸烷-1β-醇

Sigma货号UC18-10mg现货(±)-土臭味素[别名:

说明

应用

(±)-土腥素已被用作基于GC-MS的分析技术的标准。土腥素也被用于研究其在活性炭上的吸附。

生化/生理作用

(±)-土臭素由天蓝色链霉菌和蓝藻细菌产生。

土腥素是一种天然存在的生物分子，在供水中会产生泥土味或霉味和臭味。这种水污染物在ng/l(万亿分之一)浓度下就可以被人体检测到。

常见问题

Which document(s) contains shelf-life or expiration date information for a given product?

If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.
How do I get lot-specific information or a Certificate of Analysis?

The lot specific COA document can be found by entering the lot number above under the "Documents" section.
How do I find price and availability?

There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page. You can contact any of our Customer Sales and Service offices to receive a quote. USA customers: 1-800-325-3010 or view local office numbers.
What is the Department of Transportation shipping information for this product?

Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product.
What can you tell me about the stereochemistry of Sigma-Aldrich's (±)-Geosmin products?

The geosmin products listed by Sigma-Aldrich (CAS Registry number [16423-19-1]) are synthetic, and would be exactly a 50:50 mixture of the (+) and (-) isomers. Specifically, the natural (-) isomer is (4S,4aS,8aR)-4,8a-Dimethyl-1,2,3,4,5,6,7,8-octahydronaphthalen-4a-ol. Therefore, the unnatural (+) isomer (the mirror image) is (4R,4aR,8aS)-4,8a-Dimethyl-1,2,3,4,5,6,7,8-octahydronaphthalen-4a-ol.This information has not been confirmed by a specific rotation measurement or chiral analysis, but is known based on the method of preparation.

Dps protein is related to resistance of Mycobacterium abscessus subsp. massiliense against stressful conditions.

Nayra Rodrigues de Alcântara et al.

Applied microbiology and biotechnology, 104(11), 5065-5080 (2020-04-08)

Mycobacterium abscessus subsp. massiliense (Mycma) belongs to the Mycobacterium abscessus complex and is a rapidly growing non-tuberculous mycobacterium. The chronic pulmonary, skin, and soft tissue infections that it causes may be difficult to treat due to its intrinsic resistance to

Analysis of 2-methylisoborneol and geosmin in catfish by microwave distillation--solid-phase microextraction.

S W Lloyd et al.

Journal of agricultural and food chemistry, 47(1), 164-169 (1999-11-24)

The semivolatile cyclic alcohols 2-methylisoborneol (MIB) and geosmin (GSM) impart muddy or musty flavors to water and food products. A rapid quantitative analytical technique has been developed whereby microwave distillation is used to remove the volatile organic compounds from a

Frontiers in cellular and infection microbiology, 10, 408-408 (2020-09-10)

On the surface of the Leishmania promastigote, phosphoglycans (PG) such as lipophosphoglycan (LPG), proteophosphoglycan (PPG), free phosphoglycan polymers (PGs), and acid phosphatases (sAP), are dominant and contribute to the invasion and survival of Leishmania within the host cell by modulating

PCR-targeted Streptomyces gene replacement identifies a protein domain needed for biosynthesis of the sesquiterpene soil odor geosmin.

Bertolt Gust et al.

Proceedings of the National Academy of Sciences of the United States of America, 100(4), 1541-1546 (2003-02-04)

Streptomycetes are high G+C Gram-positive, antibiotic-producing, mycelial soil bacteria. The 8.7-Mb Streptomyces coelicolor genome was previously sequenced by using an ordered library of Supercos-1 clones. Here, we describe an efficient procedure for creating precise gene replacements in the cosmid clones

In-depth synthetic, physicochemical and in vitro biological investigation of a new ternary V(IV) antioxidant material based on curcumin.

E Halevas et al.

Journal of inorganic biochemistry, 191, 94-111 (2018-11-27)

Curcumin is a natural product with a broad spectrum of beneficial properties relating to pharmaceutical applications, extending from traditional remedies to modern cosmetics. The biological activity of such pigments, however, is limited by their solubility and bioavailability, thereby necessitating new
