Secondary fatty alcohols of Mycobacterium xenopi [PDF]

Journal of General Microbiology, 1992
Secondary alcohols of Mycobacterium xenopi were studied by gas chromatography and gas chromatography-mass spectrometry. Mycobacterial cells were hydrolysed and the liberated alcohols separated by extraction and analysed both underivatized and as trimethylsilyl, methyl ether- and pentafluorobenzoyl derivatives.

Naturally occurring long-chain β-hydroxyketones

Journal of Lipid Research, 1971
A fraction comprising about 0.7% of the extractable surface lipids of cabbage (Brassica oleracea) leaves was isolated and identified as a mixture of isomeric βhydroxyketones consisting mainly of 14-keto-16-hydroxynonacosane and 15-keto-13 ...
