| Common Name | 7,7',8,8'-Tetrahydro-beta,beta-carotene |
|---|
| Description | 7,7',8,8'-Tetrahydro-beta,beta-carotene belongs to the class of organic compounds known as carotenes. These are a type of unsaturated hydrocarbons containing eight consecutive isoprene units. They 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. Thus, 7,7',8,8'-tetrahydro-beta,beta-carotene is considered to be an isoprenoid. Based on a literature review a small amount of articles have been published on 7,7',8,8'-Tetrahydro-beta,beta-carotene. |
