The Multiple Roles of Urocanic Acid in Health and Disease.
Hart PH, Norval M. Hart PH, et al. J Invest Dermatol. 2021 Mar;141(3):496-502. doi: 10.1016/j.jid.2020.07.017. Epub 2020 Sep 9. J Invest Dermatol. 2021. PMID: 32919759 Free article. Review.
Trans-urocanic acid (trans-UCA) is synthesized in the skin, liver, and brain. It is a major natural moisturizing factor in skin and maintains its acid pH. In skin, it isomerizes to cis-UCA following exposure to UVR. ...
