Hi,
I  can code the cycle in ConTeXt,but it's too ugly and I will try=
to improve it.
here is my code:

\starttext
\placeformula
\startformula
\matrix{A+B&{\Delta G_1\atop\rightleftharpoons}&AB\cr
\Delta G_3\!\!\upharpoonleft\!\downharpoonright&&
\upharpoonleft\!\downharpoonright\!\!\Delta G_4\cr
A'+B&{\rightleftharpoons\atop\Delta G_2}&A'B\cr}
\stopformula
\stoptext

There is a similar example in "The TeXbook"(example 18.46).
You can try the follow code:

$$\def\normalbaselines{\baselineskip20pt \lineskip3pt \lineskiplimit3pt } \def\mapright#1{\smash{ \mathop{\longrightarrow}\limits^{#1}}} \def\mapdown#1{\Big\downarrow \rlap{\vcenter{\hbox{\scriptstyle#1}}}} \matrix{&&&&&&0\cr &&&&&&\mapdown{}\cr 0&\mapright{}&{\cal O}_C&\mapright\iota& \cal E&\mapright\rho&\cal L&\mapright{}&0\cr &&\Big\Vert&&\mapdown\phi&&\mapdown\psi\cr 0&\mapright{}&{\cal O}_C&\mapright{}& \pi_*{\cal O}_D&\mapright\delta& R^1f_*{\cal O}_V(-D)&\mapright{}&0\cr &&&&&&\mapdown{\theta_i\otimes\gamma^{-1}}\cr &&&&&&\hidewidth R^1f_*\bigl({\cal O} _V(-iM)\bigr)\otimes\gamma^{-1}\hidewidth\cr &&&&&&\mapdown{}\cr &&&&&&0\cr}$$

Since i'm just a newbie of TeX, I don't really understand the=
first a few lines
of the solution. I still need some learning and practice :)
