| Product Name | all-trans Retinal (Vitamin A Aldehyde, Retinene, Retinylaldehyde) |

| Description | Purity ~95%. Corotenoid component of the visual pigments. All-trans retinal is converted to retinoic acid in vivo by the action of retinal dehydrogenase. Retinal is also known as retinaldehyde. It was originally called retinene,[2] and renamed[3] after it was discovered to be vitamin A aldehyde.[4][5] Retinal is one of the many forms of vitamin A (the number of which varies from species to species). Retinal is a polyene chromophore, bound to proteins called opsins, and is the chemical basis of animal vision. Retinal allows certain microorganisms to convert light into metabolic energy. Vertebrate animals ingest retinal directly from meat, or they produce retinal from carotenoids, either from one of two carotenes (α-carotene, β-carotene) or from β-cryptoxanthin, a type of xanthophyll. These carotenoids must be obtained from plants or other photosynthetic organisms. No other carotenoids can be converted by animals to retinal, and some carnivores cannot convert any caroteno |
