Optical and geometric isomers of some fatty acids with vicinal hydroxy groups

Some Geometric Groups with Rapid Decay

We explain simple methods to establish the property of Rapid Decay for a number of groups arising geometrically. Those lead to new examples of groups with the property of Rapid Decay, notably including non-cocompact lattices in rank one Lie groups.

Isolation and determination methods for brain cerebrosides, hydroxy fatty acids, and unsaturated and saturated fatty acids *

A new method is described for the isolation of nearly pure total cerebrosides from fresh brain. Florisil columns are used to separate the cerebroside hydroxy and normal acids, in the form of their esters, and to separate the saturated and unsaturated esters of each group. The esters within each class are determined by gas chromatography, the hydroxy esters being run as the methyl ethers. Yields...

Fatty Acids: Hydroxy and Other Oxygenated Structures, Occurrence and Biochemistry

The following is a guide to the more important naturally occurring fatty acids with hydroxy, epoxy (furanoid), methoxy and oxo substituents, but it is not intended to be a comprehensive list. The prostaglandins and other eicosanoids and the plant oxylipins are in essence fatty acids with additional oxygenated functional groups, but these are discussed elsewhere in this website. Similarly, hydro...

A representation for some groups, a geometric approach

‎In the present paper‎, ‎we are going to use geometric and topological concepts‎, ‎entities and properties of the‎ ‎integral curves of linear vector fields‎, ‎and the theory of differential equations‎, ‎to establish a representation for some groups on $R^{n} (ngeq 1)$‎. ‎Among other things‎, ‎we investigate the surjectivity and faithfulness of the representation‎. At the end‎, ‎we give some app...
