WebAug 13, 2024 · As discussed here, in metabolomics, the first layer of InChIKey can be used for searching metabolites. For example, the second layer's key "UHFFFAOY" means "it does not have stereoisomer information". The last three characters like "NA-N" describe (1) N/S: standardized or not (2) A: version of InChIKey (3) -N: ionized form (proton state).
