Lipids of the Streptomycettes. Structural investigation and biological interrelation a review.

During a systematic investigation of lipids of Streptomycetes a series of compounds of biochemical and microbiological interest have been isolated and characterized. These include several menaquinones, glycosyl diglycerides (glucuronosyl and isoladobinosym diglycerides), two ornithino lipids and a diol phospholipid. Some of these lipids were not known previously as constituents of streptomycete cells although they have been encountered elsewhere; others have proved to be novel lipids. The results of structural studies of these lipids are reviewed and some of their possible biological functions are discussed.
