Aliphatic, non-hydrolyzable biopolymers were subjected to RuO 4 -oxidation in order to examine the potential of this method in revealing details on their structures. The method was tested on model compounds first and found to cleave alkyl chains of aromatic moieties, double bonds and ether bonds. Oxidation of the biopolymer cutan derived from cuticles of Agave americana and the algaenans isolated...
Ester-bound lipids from the cell walls of the green algae, Tetraedron minimum, Scenedesmus communis and Pediastrum boryanum, were analysed by gas chromatography-mass spectrometry. The double bond positions of the C 30 , C 32 and C 3 mono- and C 30 and C 32 diunsaturated ω-hydroxy fatty acids obtained were determined by derivatisation with...
