Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify.

Purpose and description
Enable an AI agent to recognise aldosterone, assess the identity and fitness of a material or measurement, and determine which handling, analytical or biological interpretations are justified.
Aldosterone is a C21 steroid mineralocorticoid hormone produced chiefly by the adrenal cortex's zona glomerulosa that promotes renal sodium reabsorption and potassium excretion through mineralocorticoid receptor activation, helping regulate extracellular fluid volume and blood pressure.
It can be Resolve a name or identifier to a verified aldosterone identity and flag conflicting records.; Evaluate whether an aldosterone lot or stock solution is suitable for a specified analytical or research task.; Compare aldosterone measurements after checking units, analyte definition, matrix and method.; Trace an aldosterone preparation or result to its source, certificate and supporting evidence.; Identify missing biological context that prevents interpretation of an aldosterone result.; Select documented handling and storage requirements for the actual preparation..
Distinguishing features
Require agreement with a verified aldosterone structure, including stereochemistry, rather than accepting a steroid-family label or molecular formula alone.
Distinguish aldosterone from related steroids such as corticosterone and cortisol through structure-specific identification or demonstrated analytical separation.
Identify isotope-labelled aldosterone separately from unlabelled aldosterone when evaluating reference materials and analytical results.
Separate unconjugated aldosterone from conjugates, metabolites and quantities reported after hydrolysis.
Distinguish the substance from an aldosterone-containing solution, biological specimen or product by recording the surrounding matrix and actual aldosterone content.

Characteristics
- Verified chemical identity
- Structure, stereochemistry, molecular formula and source-verified CAS, PubChem and applicable regulatory identifiers Prevents a synonym, related steroid or preparation identifier from being mistaken for the substance.

- Preparation and matrix
- Neat material; solution with named solvent; biological specimen with named matrix Controls how concentration, stability, hazards and analytical suitability should be interpreted.
- Purity and impurity profile

- Mass fraction, mol/L or mass/volume with uncertainty, matrix and measurement method Makes quantities comparable while preserving the distinction between stock solutions and specimen results.
- Physical properties under stated conditions
- Phase; melting or decomposition behaviour in °C; solubility with solvent and temperature; boiling data only if established Supports preparation and handling without treating unsupported constants as known.
- Storage and stability status
- Documented conditions met; excursion recorded; expired; stability unverified Determines whether an identified material remains fit for its intended use.
- Biological production and action
- Evidence-linked producing tissue, regulatory inputs, molecular targets and transformations, with species and experimental context Connects aldosterone to physiology without attributing an entire organism's condition to one substance measurement.
- Hazard and use status
