Imidazole dipeptides, that are ample in meat and fish, are substances produced within the our bodies of varied animals, together with people, and have been reported to be efficient in relieving fatigue and stopping dementia. Nevertheless, the physiological mechanism by which IDPs exhibit these actions had not been decided beforehand.
A analysis workforce, led by Professor Hideshi Ihara from the Osaka Metropolitan College Graduate College of Science, was the primary to find 2-oxo-imidazole-containing dipeptides —which have yet one more oxygen atom than regular IDPs—and located that they’re the most typical number of IDPs derivatives within the physique. The researchers additionally discovered that they’ve remarkably excessive antioxidant exercise.
Of their examine, the researchers established a technique for selective and extremely delicate detection of 5 sorts of 2-oxo-IDPs utilizing mass spectrometry, which permits quantitative detection of hint 2-oxo-IDPs in residing organisms. Utilizing this technique, they revealed for the primary time that beef, pork, rooster and different meats comprise antioxidants, not solely IDPs however a wide range of completely different 2-oxo-IDPs. Their findings had been printed in Antioxidants.
“We hope that this analysis technique, which permits superior evaluation of 2-oxo-IDPs, will likely be utilized not solely to fundamental biology but in addition to drugs, agriculture and pharmacy, the place it would assist enhance peoples’ well being and stop illnesses,” concluded Professor Ihara.
