Used in biochemical and plant physiology research to quantify uroporphyrinogen III levels, aiding studies on tetrapyrrole biosynthesis pathways such as heme and chlorophyll production. Enables monitoring of enzyme activities and metabolic fluxes in plant systems, particularly in mutants or under stress conditions affecting photosynthesis and pigment synthesis. Supports investigation into regulatory mechanisms of porphyrin metabolism and identification of metabolic bottlenecks in plant development and response to environmental factors.
