| Abstract: | Astaxanthin isolated from the yeast Phaffia rhodozyma has the 3R,3′R-configuration, opposite to that of astaxanthin from other sources which have been so far investigated. This is the first example of a naturally occurring carotenoid biosynthesized in different optical forms. A possible explanation is advanced. |
