where TH is the time horizon over which the calculation is considered ; a < sub > x </ sub > is the radiative efficiency due to a unit increase in atmospheric abundance of the substance ( i. e., Wm < sup >− 2 </ sup > kg < sup >− 1 </ sup >) and is the time-dependent decay in abundance of the substance following an instantaneous release of it at time t = 0.

-Tyrosine is converted into-DOPA by the enzyme tyrosine hydroxylase ( TH ) with tetrahydrofolic acid ( THFA ), O < sub > 2 </ sub >, and ferrous iron ( Fe < sup > 2 +</ sup >) as cofactors.

* TH :-Tyrosine + THFA + O < sub > 2 </ sub > + Fe < sup > 2 +</ sup > →-DOPA + DHFA + H < sub > 2 </ sub > O + Fe < sup > 2 +</ sup >

Likewise, < tt > TH </ tt >, < tt > ER </ tt >, < tt > ON </ tt >, and < tt > AN </ tt > are the most common pairs of letters ( termed bigrams or digraphs ), and < tt > SS </ tt >, < tt > EE </ tt >, < tt > TT </ tt >, and < tt > FF </ tt > are the most common repeats.
