<br />
The reaction proceeds in the opposite direction. A step in [[riboflavin]] biosynthesis, NADPH and NADH functions equally well as a [[reductant]].<br />

In mathematics, the '''Poincaré–Lelong equation''', studied by {{harvs|txt|last=Lelong|authorlink=Pierre Lelong|year=1964}}, is the [[partial differential equation]]<br />
:<math>i\partial\overline\partial u=\rho</math><br />
on a [[Kähler manifold]], where ρ is a positive (1,1)-form.<br />
