Fellow bio-inorganic chemists, we think the hydrophobic pocket in hemoglobin/myoglobin not only prevents auto-oxidation of the heme (stabilize the oxy-heme) but also helps keep the active site five co-ordinate high spin which is vital for oxygen binding. https://t.co/M9NvjeeQAR

@IndiaDST @CSIR_IND @ICMRDELHI @DBTIndia DSIR certificate provides BCD exemption to public funded research institutes as per notification 51/96-customs. But the notification does not use the description "chemicals" it uses "consumables". A clarification in that regard is needed.
