Role of hydrophobicity in the binding of coenzymes. Appendix. Translational and rotational contribution to the free energy of dissociation.

Biochemistry, 1978
We calculate the loss of surface area accessible to solvent associated with coenzyme binding in Clostridium flavodoxin, in dogfish lactate dehydrogenase, and in lobster glyceraldehyde-3-phosphate dehydrogenase.

Coenzyme Q10 in Pregnancy

Fetal Diagnosis and Therapy, 1996
Our objectives were to assess the plasma coenzyme Q10 (CoQ10) levels in normal pregnancy, in pregnancy with a spontaneous contractile event, in spontaneous abortion and in threatened abortion. Six hundred and fifteen CoQ10 levels were analyzed in 483 pregnant women: 350 patients were employed to design a normal curve; 66 patients with spontaneous ...

Efficient Synthesis of Radiolabeled Propionyl-Coenzyme A and Acetyl-Coenzyme A

Analytical Biochemistry, 1995
The efficient microscale synthesis of [1-14C]propionyl-CoA from commercially available sodium [1-14C]-propionate using 1,1'-carbonyldiimidazole in yields of nearly 70% is reported for the first time. A substantial improvement in the process for making [1-14C]acetyl-CoA from sodium [1-14C]acetate was also achieved.

Comparison of in-line connected diode array and electrochemical detectors in the high-performance liquid chromatographic analysis of coenzymes Q(9) and Q(10) in food materials.

Journal of Agricultural and Food Chemistry, 2000
In-line connected electrochemical (EC) and diode array (DAD) detectors were compared in the reversed-phase high-performance liquid chromatographic (RP-HPLC) analysis of coenzymes Q(9) and Q(10) in some food materials (beef steak, beef heart, Baltic ...

Thermodynamic trans-effects of the nucleotide base in the B12 coenzymes

, 1987
The 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 ...
