Production of vitamins, coenzymes and related biochemicals by biotechnological processes.
Journal of chemical technology and biotechnology, 2007Vitamins and related biofactors belong to those few chemicals with a direct positive appeal to people. There is indeed a large need for extra vitamins, other than those derived from plant and animal food sources, due to unbalanced food habits or ...

Coenzymes Q9and Q10: Contents in Foods and Dietary Intake
, 2001Coenzyme Q9and Q10contents in 35 food items were determined and coenzyme Q intake of Finns was estimated. The analytical method employed direct solvent extraction or saponification before extraction and quantification using high-pressure liquid ...

Thermodynamic trans-effects of the nucleotide base in the B12 coenzymes
, 1987The thermodynamic effects of the nucleotide coordination on the Co-C bond strengths in the B12 coenzymes were analyzed. Methyl group transfer reactions from methylcob(III)inamides to cob(II)inamides and cob(I)inamides in neutral aqueous solution were ...
