# Fix an arrow in chemfig

I'm using chemfig to write a reaction of sucrose degradation, but the first arrow is too near the + sign. I tried using \indent but it didn't work.

\definesubmol{x}{(-[4]H)(-[0]OH)}
\definesubmol{y}{(-[0]H)(-[4]HO)}

\schemestart
\chemname{\chemfig{[2]CH_2 \cdot OH-!x-!x-!y-(-[0]OH)=(-[3]H)-[1]OH}}{1, 2 Enediol}
\arrow
\indent \indent \indent \+
\arrow(--tri){0}[90,0.15]
\indent \indent \indent \chemname{\chemfig{[2]CH_2 \cdot OH-(-[0]OH)=(-[3]H)-[1]OH}}{Triosa Enediol}
\arrow(--gli){0}[-90,0.30]
\indent \indent \indent \chemname{\chemfig{[2]CH_2 \cdot OH-(-[4]H)(-[0]OH)-(-[3]H)=[1]O}}{D-Gliceraldehído}
\arrow(--met)
\chemname{\chemfig{[2]CH_3-(=[0]O)-(-[3]H)=[1]O}}{Metilglioxal}
\arrow(@tri.mid east--@met)[-45]
\arrow
\chemname{\chemfig{[2]CH_3-!x-(-[3]HO)=[1]O}}{D-Ácido Láctico}
\arrow(@tri--){<=>}
\chemname{\chemfig{[2]CH_2 \cdot OH-(=[0]O)-CH_2 \cdot OH}}{Dihidroxiacetona}
\schemestop


• Have you tried inserting \hspace{5mm} or something like this? – Raven Oct 2 '19 at 16:34
• No. It worked pretty well, by adding 7 mm to both molecules and 5 mm to the + sign. Thanks. – AJMC2002 Oct 2 '19 at 17:13

Turning my comment into an answer: In order to add horizontal space, you can use the \hspace command right after the +. E.g. +\hspace{7mm}.
