Reaction of Cob(I)alamin with nitrous oxide and Cob(III)alamin

Reaction of Cob(I)alamin with nitrous oxide and Cob(III)alamin Cob()alamin (vitamin B) has been generated by pulse radiolysis of NO-saturated solutions of cob()alamin (vitamin B) containing sodium formate. It reacts with NO with rate constants in the range 200–1200 dm mol s, depending on pH and buffer concentration. The final product is cob(II)alamin, formed in 100 % yield. The initial product is thought to be cob()alamin (vitamin B or B) but this does not build up to significant concentrations. Cob()alamin (vitamin B or B) reacts with cob()alamin with a rate constant of 3.2 × 10 dm mol s independent of pH in the range 5.8–11.0. Cyanocobalamin (vitamin B) does not react with cob()alamin. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of the Chemical Society Faraday Transactions 1 Physical Chemistry in Condensed Phases Royal Society of Chemistry

Abstract

Cob()alamin (vitamin B) has been generated by pulse radiolysis of NO-saturated solutions of cob()alamin (vitamin B) containing sodium formate. It reacts with NO with rate constants in the range 200–1200 dm mol s, depending on pH and buffer concentration. The final product is cob(II)alamin, formed in 100 % yield. The initial product is thought to be cob()alamin (vitamin B or B) but this does not build up to significant concentrations. Cob()alamin (vitamin B or B) reacts with cob()alamin with a rate constant of 3.2 × 10 dm mol s independent of pH in the range 5.8–11.0. Cyanocobalamin (vitamin B) does not react with cob()alamin.
