Application: Retinol has been used:
• as a standard in peak identification and quantification in reverse phase HPLC
• as a standard to estimate the concentration of vitamin A
• to study the inhibitory effect of retinol on murine norovirus (MNV) replication in murine RAW 264.7 cells
• as a component in the reaction mixture for the lecithin:retinol acyltransferase (LRAT) assay
Biochem/physiol Actions: It is not biologically active and works as a precursor of active retinoids. Retinol is converted to retinaldehyde and subsequently to retinoic acid.
Biochem/physiol Actions: Retinal, retinol and retinoic acid are the aldehyde, alcohol and acid forms of vitamin A. The retinoids exist as many geometric isomers due to the unsaturated bonds in the aliphatic chain.
Retinol is biological active in a wide range of processes.
General description: Retinol or vitamin A alcohol is the main circulating form of vitamin A.
Packaging: Bottomless glass bottle. Contents are inside inserted fused cone.
