Professor Sabyasachi Sarkar ( born in 17 May 1947) is an Indian Chemist. He has explored chemistry passionately as a prospector to observe closely the clandestine activities of nature. He has worked and continued working in the diverse branches of chemistry closely related to natural set up and as such his research embraces functional models related to hyperthermophilic to mesophilic metalloproteins enriching bioinorganic chemistry. A Replica of a Fishy Enzyme and the reduced xanthine oxidase also have been made.Inhibition patterns in the Michaelis complex of low molecular weight hepatic sulfite oxidase model complex have been exhibited. He demonstrated that carbon dioxide molecule does bind to magnesium in chlorophyll in photosynthesis as proposed by R. M. Willstätter hundred years ago a
