retinyl palmitate

Retinyl palmitate (Vitamin A palmitate) is a naturally-occurring phenyl analogue of retinol, with potential antineoplastic and chemopreventive activities.

Retinyl palmitate-d4 is a deuterium-labeled form of Retinyl palmitate. Retinyl palmitate, an ester of retinol, serves as the primary form of vitamin A in the epidermis. It is extensively used in pharmaceutical and cosmetic research.

Retinyl palmitate (Standard) is the standard substance of Retinyl palmitate, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. Retinyl palmitate (Vitamin A palmitate) is a naturally-occurring phenyl analogue of retinol, with potential antineoplastic and chemopreventive activities.

5,6-Epoxyretinyl palmitate is a primary photodecomposition product of Retinyl palmitate when exposed to UVA light. It exhibits photocytotoxicity, leading to significant DNA single-strand breaks, DNA damage, and chromosomal mutations under illuminated conditions.

9-cis-Vitamin A palmitate (9-cis-Retinyl palmitate) is a 9-cis isomer derived from the interaction of vitamin A palmitate in corn flakes, exhibiting 26% of the biological activity of the all-trans-vitamin A palmitate, the most biologically active form of vitamin A.

13-cis-Vitamin A palmitate (13-cis-Retinyl palmitate), a derivative of vitamin A palmitate found in corn flakes, is the 13-cis isomer with 75% of the biological activity of the all-trans form, the most active form of vitamin A [1].
