How to prettify this chemfig figure?

I would like to create a figure of dipeptide condensation of two amino acids:

I was looking at the chemfig manual and came up with the following solution:

\documentclass{article}
\usepackage{chemfig}
\usepackage{tikz}
\begin{document}
\scalebox{1}{
\begin{tikzpicture}
\setchemfig{atom sep=2.2em}
\setchemfig{arrow offset=3pt,arrow coeff=0.7}
\schemestart
\chemname{\chemfig{N(-[:120]H)(-[:-120]H)-C(-[:90]H)(-[:-90]\color{orange}{R_1})-\color{red}{C}(=[:60]\color{red}{O})(-[:-60]\color{blue}{OH})}}{Amino acid 1}
\+
\chemname{\chemfig{\color{red}{N}(-[:120]\color{red}{H})(-[:-120]\color{blue}{H})-C(-[:90]H)(-[:-90]\color{violet}{R_2})-C(=[:60]O)(-[:-60]OH)}}{Amino acid 2}
\arrow(.mid east--.mid west)
\chemname{\chemfig{N(-[:120]H)(-[:-120]H)-[:30]C(-[:90]H)(-[:-90]\color{orange}{R_1})-[:-30]\color{red}{C}(=[:-90]\color{red}{O})-[:+30]\color{red}{N}(-[:90]\color{red}{H})-[:-30]C(-[:90]H)(-[:-90]\color{violet}{R_2})-[:+30]C(=[:60]O)(-[:-60]OH)}}{Dipeptide}
\+
\chemname{\chemfig{\color{blue}{H_2O}}}{Water}
\schemestop
\chemnameinit{}
\end{tikzpicture}
}
\end{document}


How can I make it more appealing and align the elements and the labels better?

• have a look a this answer -- the same can be edited to meet your requirement -- please revert --tex.stackexchange.com/a/553958/197451 Jul 18 '20 at 0:21
• Be more specific, "more attractive" is relative and can be interpreted differently by different people. Say exactly what you want to achieve, if necessary by adding a freehand drawing of the desired result. Jul 19 '20 at 18:21
• @AndréC I just want the LHS and the RHS to align better with each other, but I am not opposing to any other improvements.

• I'm not a chemist and I don't know what LHS and RHS is. Jul 19 '20 at 18:46
• It looks well aligned to me, what do you think is the problem here? Jul 19 '20 at 19:52
