Triterpenoid carotenoids and related lipids. Triterpenoid carotenoid aldehydes from Streptococcus faecium UNH 564P.
1. The identification of two novel triterpenoid xanthophylls from Streptococcus faecium UNH 564P is described. 2. Both are aldehydes and were identified as 4,4'-diaponeurosporen-4-al and 4,4'-diapolycopen-4-al. 3. A pathway is presented for the biosynthesis of these and other triterpenoid carotenoids in S. faecium.
