Study Title | Discovery of phytochelatins in human urine: Evidence for function in selenium disposition and protection against cadmium |
Study Summary | The goal of this project was to detect phytochelatins, plant-derived peptides which function as metal chelators, in human urine. Untargeted metabolomics of 143 urine samples from healthy adults was performed. Phytochelatin 2, γE-C-γE-C-G, was detected, and the rest of the urine metabolome was searched for phytochelatins and predicted phytochelatin metabolites which correlated with phytochelatin 2 concentrations. Phytochelatin 2 and associated metabolites were found to correlate with urinary metals, and further experiments were performed provide insight into function of dietary phytochelatins. |
