In my StackOverflow post, Creating a metabolic pathway in Neo4j I describe how I created and linked two metabolic pathways (glycolysis, and the TCA cycle).

Please refer to that post, as it is very complete.

Notably, in my "follow-on" answer (there), I describe an issue that initially vexed me - and my solution:

An issue that arose during the creation of my "TCA pathway" graph was that the one of the nodes (the enzyme, `aconitase`) was used twice, so during the graph creation "MERGE" merged the common node "aconitase" as a single entity, resulting in this layout,

... not this one, as desired,

My solution to that issue was to create the "TCA graph" using node properties, to temporarily differentially-tag the affected source and target nodes (later removing those tags, after the graph was properly created). ...

Here is that final graph, in the Neo4j Browser:
