title: Bacterial carotenoids. L. Absolute configuration of zeaxanthin dirhamnoside.
abstract: Zeaxanthin dirhamnoside is the major carotenoid of Corynebacterium autotrophicum. The absolute configuration 3R,3'R followed from CD-properties of its hexaacetate, alpha-L-assignment and 1C4 conformation were concluded from 1H NMR data by comparison with model compounds.
