So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Zhang, Li-yuan; Dai, An-na; Yu, Run-zhong; Ruan, Chang-qing; Li, Zhi-jiang; Zhang, Dong-jie researched the compound: (2R,3R,4S,5R,6R)-2-(Hydroxymethyl)-6-methoxytetrahydro-2H-pyran-3,4,5-triol( cas:1824-94-8 ).Related Products of 1824-94-8.They published the article 《Analysis of metabolites of soybeans from different producing origins in Heilongjiang Province based on metabonomics》 about this compound( cas:1824-94-8 ) in Xiandai Shipin Keji. Keywords: metabonomic soybean metabolism gas chromatog mass spectrometry. We’ll tell you more about this compound (cas:1824-94-8).
Metabolites of Heihe 43 soybeans in three origins (Beian Longmen, Weishan and Yinlong River) were isolated and identified using non-targeted metabolic profiling based on gas chromatog.-mass spectrometry. The metabolites in the soybean samples were extracted by 80% methanol, derivatized with N,O-bis(trimethylsilyl)trifluoroacetamide, eluted on an HP-5ms column, detected with GC-MS. The metabolic pathways of the differential metabolites were analyzed by KEGG annotation, the metabolic mechanisms were explored. A total of 68 metabolites were detected in soybean samples, and 62 metabolites were isolated and identified, included 22 carbohydrates and their derivatives, 14 fatty acids and their derivatives, 7 alcs., 4 esters, and 2 amino acids, and 13 kinds of intermediates, inferring the structure of 6 kinds of unknown metabolites, 4 kinds of WS-soy samples, 2 kinds of YLH-soy samples. Soybean metabolites and metabolic mechanisms were different in different producing areas, and they had the attributes of producing areas. This not only provides a theor. basis for the quality anal. of soybeans in cold regions, and also provides a basis for soybean classification and processing or extraction of functional components by origin.
