The latest issue of #JAFC is now online!

Our work on the regulation of tyrosinase #enzyme activity by glutathione peroxidase mimics is highlighted on the front cover of this week's issue of #JAFC. Thanks to @serbonline for financial support.

[ACS agricultural and food journals @JAgFoodChem]

The latest issue of #JAFC is now online!

Our front cover this week shows the regulation of tyrosinase #enzyme activity by selone-based glutathione peroxidase (GPx) mimics. Read the article by @GouriprasannaR et al. at https://t.co/SsrG3QpPar

[Gouriprasanna Roy @GouriprasannaR]

The activity of tyrosinase, a key enzyme responsible for the biosynthesis of melanin pigments, can be regulated by glutathione peroxidase mimics (https://t.co/2yPVnbCC5i). Thanks to @serbonline...Shout out to my students Rakesh, Ramesh, and our wonderful collaborator @kshatresh.

It is happening again....Conference of the Society for Advanced Biological Inorganic Chemistry 2024. 1st Week of January 2024. Kolkata, India.
We had a blast back in 2017 and we skipped 2022 for travel limitations.
But 2024 will be better and bigger. Group photos from 2017.
