Biodegradation of 2-Sulfonatofatty Acid Methyl Ester (α-SFMe)

5-(6-Hydroxy-2,5,7,8-tetramethylchroman-2-yl)-2-methyl-pentanoic Acid Methyl Ester

A natural diastereomeric mixture of 5-(6-hydroxy-2,5,7,8-tetramethyl-chroman2-yl)-2-methyl-pentanoic acid methyl ester (1), was isolated from the soft coral Sinularia arborea. The structure of 1 was elucidated by spectroscopic methods and 1 displayed a significantly inhibitory effect on the generation of superoxide anion by human neutrophils.

2-Aminoterephthalic acid dimethyl ester

Single crystals of the title compound, C(10)H(11)NO(4), an inter-mediate in the industrial synthesis of yellow azo pigments, were obtained from the industrial production. The mol-ecules crystallize as centrosymmetic dimers connected by two symmetry-related N-H⋯O=C hydrogen bonds. Each mol-ecule also contains an intra-molecular N-H⋯O=C hydrogen bond. The dimers form stacks along the a-axis direc...

FATTY ACID METHYL ESTER PROFILING OF Enterococcus and E

Crystal structure of 2-[N-(t-butoxycarbonyl)amino]-4-(thymin-1-yl)-butyric acid methyl ester.

psuedopeptide backbone composed of N-(2-aminoethyl) glycine units, and nucleobases are attached by methylene carbonyl linkers (Fig. 1). Since the binding of PNA to DNA inhibits transcription, the potential of PNA has been focused to target an antisense drug.1 Moreover, PNA-peptides hybridization and improvements of the PNA backbone unit were developed to form DNA-DNA-PNA triplexes with nonspeci...

Automated determination of fatty acid methyl ester and cis/trans methyl ester composition of fats and oils.

The determination of the fatty acid composition (as methyl esters, FAMEs) of fats and oils and their cis/trans (CTME) distribution requires a simple, but manual and time-consuming sample preparation. The so-called BF3 method is often the preferred procedure. Because FAME/CTME analyses are encountered very frequently in the food industry, an automated, robot-based alternative is proposed which u...
