How to read the library
Molecular values describe a specific source record. Salts, counterions, peptide sequences and modifications can change that identity. A 2D diagram is a reference depiction, not an analysis of a vendor batch. When a record is unresolved, we show the gap instead of assigning a similar molecule.
PubMed publication types help organize the selected bibliography; they do not grade study quality or prove a treatment effect. Reviews and encyclopedia articles provide context. The original methods, population, formulation, controls and limitations must be checked before interpreting an experiment.
