ChEBI: Cis-urocanic acid is a urocanic acid in which the double bond of the carboxyethene moiety has Z configuration. It is a conjugate acid of a cis-urocanate.
cis-Urocanic acid (cis-UCA) affects the immune cells of the body and is excreted in the urine due to photoisomerization. It inhibits tumor immunity through photocarcinogenesis in mice. cis-Urocanic acid has been studied to prevent UV-radiation-induced DNA damage leading to skin cancer.
