| Common Name | 1,2-Dihydro-1-methoxy-psi,psi-caroten-4-one |

| Description | R.G.Keto-i belongs to the class of organic compounds known as xanthophylls. These are carotenoids containing an oxygenated carotene backbone. Carotenes are characterized by the presence of two end-groups (mostly cyclohexene rings, but also cyclopentene rings or acyclic groups) linked by a long branched alkyl chain. Carotenes belonging form a subgroup of the carotenoids family. Xanthophylls arise by oxygenation of the carotene backbone. Thus, r.G.Keto-I is considered to be an isoprenoid. 1,2-Dihydro-1-methoxy-psi,psi-caroten-4-one is found in Rhodopila globiformis and Rhodopila globiformis 7950. Based on a literature review very few articles have been published on R.G.Keto-i. |
