| Description | 9-cis-Vitamin A palmitate (9-cis-Retinyl palmitate) is a 9-cis isomer resulting from the interaction of vitamin A palmitate in corn flakes. It exhibits a biological activity of 26% compared to all-trans-vitamin A palmitate, which is known to be the most biologically active form of vitamin A. |
| In vitro | Of the total vitamin A palmitate content, 5% is the 13-cis and less than 1% is the 9-cis with 94% being all-trans[1]. |
| Synonyms | 9-cis-Vitamin A palmitate, 9-cis-Retinyl palmitate |
