7,8-dimethyl-10-ribityl-isoalloxazine, and of flavin mononucleotide (FMN2), also known as riboflavin 5′-phosphate, via potentiometric pH titrations (I = 0.1 M, NaNO3; 25 °C). In contrast to various claims, the isoalloxazine ring cannot be protonated at pH > 1, a result in ...
Will a solution that contains HCN and HNO3 form a buffer? Explain. Nitrous acid, HNO2, has a Ka of 7.1 x 10^-4. What is the H3O+ in a 0.60 M solution of HNO2? Is a solution that is 0.100 M in HNO3 and 0.100 M in NaNO3 a buffer solution? Explain. What ...
wild type and mutants were grown photoautotrophically at 30 °C in BG11 medium (29) with or without (in the case of BG110) 17.6 mm NaNO3, without the source of iron (no ferric ammonium citrate added; BG11−Fe). Mutant strains were grown in the presence of 6 μg ml−1 ...
