As it was introduced in a previous post, the diagram of an organic molecule can be edited in a latex file instead of using a figure created with some specific software.
These are some examples that can be improved, for sure. But they can be used as starting point if you have to include an amino acid in your document.
In addition to the packages related to PPChTex, you will need to add in your file: \usepackage{color}

Thanks for sharing the code for this. A time saver for many.
Yeah, thanks for sharing! I’m considering to use one or two of these for my thesis. đŸ™‚
Btw, a suggestion: ignoring hydrogens may improve readability a lot.
can you explain each line?
For more info have a look to the links in the third paragraph of this post:
