Abstract

We investigated the reduction of riboflavin-2′, 3′, 4′, 5′-tetra-acetate (AcB2), riboflavin- 1′-glucoside-2 ″, 3 ″, 4 ″, 6 ″, 2′, 3′, 4′, 5′-hepta-acetate (AcB2gl) and lumiflavin using m-thiocresol (mTc) in the presence of tetrabutylammonium hydroxide. The series of rate constants for AcB2 and AcB2gl reductions indicated that modified Lineweaver–Burk plots were best fit by assuming a 1: 2 complex formation. The complex formation in the ...
