Wherever available, both chromatographic and mass spectrometric
evidence is presented for specific phospholipid involvement in the biochemical transformations accompanying metabolic signalling events and, where possible, controversies have been resolved on basis of analytical ambiguity. The review of the lipid
analyses extends to products of phosphatidylinositol kinases, phosphatases and lipases.
A general review chapter is included on metabolic signalling with special emphasis on the lipid products of 3-kinases. In view of the general lack of commercially available standards for inositol phospholipids and inositol phosphates, the book concludes with a chapter on the preparation and collection of chromatographic and mass spectrometric proof of their purity and identity.
This book complements recent books and reviews on the mechanisms metabolic signalling, receptor binding and the polypeptide structure of the proteins involved in the various signalling pathways. It also complements those texts that deal exclusively with the chemical synthesis of the phosphatidylinositols and their polyphosphates and glycans.
