Photodimerization of urocanic acid in vitro and in vivo
1.
1. Irradition of urocanic acid or urocanate frozen in aqueous solution with 280–320-mμ light produced a photodimer which was isolated by gradient elution from an anion-exchange resin.
2.
2. A similar substance was shown to be present in dilute acid extracts of guinea-pig epidermis after irradiation with 280–320-mμ light.
3.
3. The photodimer formed with 280–320-mμ light when irradiated in solution with 254-mμ light was converted to urocanic acid and smaller amounts of several other products.
4.
4. Irradiation of crystalline urocanic acid or its solutions does not produce an accumulation of the photodimer.
