retinol

Retinol (Alphalin) and derivatives of retinol that play an essential role in metabolic functioning of the retina, the growth of and differentiation of epithelial tissue, the growth of bone, reproduction, and the immune response. Dietary vitamin A is derived from a variety of CAROTENOIDS found in plants. It is enriched in the liver, egg yolks, and the fat component of dairy products.

All-trans-Anhydro Retinol (Anhydrovitamin A) is a Vitamin A metabolite commonly employed in the synthesis of multivitamin preparations[1].

All-trans-13,14-Dihydroretinol, a metabolite of all-trans-retinoic acid, is synthesized through the enzymatic action of retinol saturase on all-trans-retinoic acid.

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

β-Carotene (Provitamin A) is a naturally-occurring retinol (vitamin A) precursor obtained from certain fruits and vegetables with potential antineoplastic and chemopreventive activities. As an anti-oxidant, beta carotene inhibits free-radical damage to DNA.

Retinyl acetate (Vitamin A acetate) is a group of unsaturated nutritional hydrocarbons, that contains retinal, retinol, retinoic acid, and several provitamins A carotenoids, among which beta-carotene is the most important.

9-cis-Retinal is a retinoid with Kd of 8 nM and 5 nM for cellular retinol binding protein-I (CRBP-1) and CRBP-II, respectively. 9-cis-Retinal accelerates the differentiation and maturation of rod photoreceptors in retinal organoids, reduces the toxicity of unliganded opsins, and can be used to study congenital stationary night blindness caused by G90D rhodopsin.
