Chemical classification systems attempt to classify
taxonomies
.
Some systems mix the various levels, resulting in hierarchies where the domains are slightly confused, for example having structural and functional aspects end up on the same level. Whereas chemical function is closely dependent on chemical structure, the situation becomes more involved when e.g.
QSAR
can usually not be directly computed from structural qualities.
Physico-chemical
- by molecular weight
- by electrical charge: uncharged, positively, negatively, partially charged
- solubility
- pH value (or pKA value)
Functional
- by functional groups
- by biological activity (mostly appropriate only for large biological molecules (as at least one interacting partner), in particular enzymes, depends on chemical functions of their constituent amino acids)
- coenzyme
- EC number
- TC number
- pharmacophore vs. non-drug
