It is not produced by the thyroid gland, but this substance is transported by the transthyretin enzyme in the human body. An organism that was genetically engineered to produce this substance was transformed with the crtI and psy genes. Light converts the cis form of one of this compound's derivatives into its trans form, which causes a G protein to hyperpolarize a photoreceptor cell after the activation of rhodopsin. Animal sources of this vitamin provide it in the form of retinol, which is responsible for the toxicity of polar bear liver.
