In other words, a ribose residue is an instance of a substructure "C1b(O2b)-C1y(O2x)-C1y(O1a)-C1y(O1a)-C1y(N1y+O2x)", which is a subclass of SKELETON.
The format of a triple is C1 rdfs:subClassOf C2, where rdfs:subClassOf is an instance of rdf:Property and states that C1, here recognized as the Gene Ontology ID, is an instance of rdfs:Class and a subclass of C2, an instance of rdfs:Class, "molecular_function".

This is the case for instance of the truncated-globin subclasses, wherein the GLB_TRO profile recruits GLB_TRP sequences (additional file 2).
As the level of information from MS studies is specific instance of subclass (e.g., 1-octadecanoyl-2-dodecanoyl-sn-glycero-3-phosphocholine) and not the common sub class itself (e.g., 1-acyl-2-acyl-sn-glycero-3-phosphocholine), a mechanism is necessary to convert generic enzymatic and pathway information from KEGG database to a specific instance under study.
The clustering of the subclass association matrix gives an indication of which candidate subclasses show the best concordance between the data sets.
