FATTY ACID METHYL ESTER PROFILING OF Enterococcus and E

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...

Glycine methyl ester hydro­chloride

THE TITLE COMPOUND [SYSTEMATIC NAME: (methoxy-carbonyl-meth-yl)ammonium chloride], crystallizes as a salt, C(3)H(8)NO(2) (+)·Cl(-), with the charged species inter-acting mutually via strong and highly directional N(+)-H⋯Cl(-) hydrogen bonds which lead to the formation of a supra-molecular tape running parallel to the c axis. Tapes close pack in the solid state mediated by multipoint recognition...
