Allgemeine Beschreibung

Palmitic anhydride reacted with 20-methyl spirolide G to form a derivative with a retention time and spectrum identical with the metabolite, 17-O-palmitoyl-20-methyl spirolide G.

Anwendung

Palmitic anhydride was used in the synthesis of water-soluble N-palmitoyl chitosan (PLCS) by coupling with swollen chitosan in dimethyl sulfoxide (DMSO). It was also used in the synthesis of N-acylphosphatidylserine.

A new phospholipid that can account for up to 40% of the total cellular phospholipid of Rhodopseudomonas sphaeroides has been identified. Purification of the phospholipid was accomplished by column chromatography on silicic acid and diethylaminoethylcellulose followed by preparative thin-layer chromatography.
