Tridecanedioic acid (Standard) is the analytical standard of Tridecanedioic acid (HY-128421). This product is intended for research and analytical applications. Tridecanedioic acid is an endogenous metabolite. Tridecanedioic acid is an endogenous metabolite. Tridecanedioic acid is related to the metabolic regulation of non-alcoholic fatty liver disease (NASH) and may be an important node molecule in the intestinal microbiota-host metabolism interaction network. Tridecanedioic acid is significantly accumulated in tolerant cabbage-type rapeseed varieties and has a lower content in sensitive varieties. It plays an important role in the defense response against the infection of the small cabbage moth (Plutella xylostella). Tridecanedioic acid can be used as a biomarker for plant insect resistance or a diagnostic marker for metabolic diseases.
