Gluconic Acid 3D Molecular Model — CAS 526-95-4

Gluconic Acid (C6H12O7, CAS 526-95-4) — a free educational 3D molecular model for teachers and students, by MolGod.org. Whatever the filament colour, each atom reads clearly thanks to its engraved symbol.

A one-colour print of a molecule hides the most basic information, which element each atom is, because STL keeps no colour data. In a MolGod model the element symbol is part of the sphere's surface, so no separate legend, sticker or colour chart is needed. The project aims to let a student work out the arrangement of atoms, the bonds and the geometry of the molecule independently, without a colour key and without waiting for the teacher. No CAD skills are needed on the teacher's side; the structure, geometry and labels come ready in one file. Curious about the science behind the engraving? The project page is at How the engraved atom letters are designed.

Ask the class whether Gluconic Acid contains a ring. It does not: 25 atoms and 24 bonds (23 single and 1 double) make up an open structure. Students work from the model back to the formula C6H12O7: the symbol count is 6 C + 12 H + 7 O, or 25 atoms all told. It makes chirality, enantiomers and CIP (R/S) rules, the carbonyl group (C=O), as well as alcohols and hydrogen bonding easier to see. Where on the model can students see the carboxylic acid group (-COOH) and the five hydroxyl groups (-OH)? Let them search before you reveal the answer. Stereocentres to find in Gluconic Acid: four in all, with CIP labels R, R, S, R. Students can check each one against the priority rules.

MolGod.org shares these models for free to make chemistry tangible in the classroom. Teachers: print one per group and let students check the structure against the formula.

Print it, hand it round and build a lesson around it. CC BY-SA 4.0 sets four simple conditions for anything you publish with it: credit "MolGod.org" as the model's author, link the original and the licence, say what you changed, and share derivatives alike. Copy the attribution line below to get it right. No sign-up, no fees and no review required. Real classroom feedback is what makes these models better. Please comment with your review and your suggestions, or write to us at Write to the MolGod team. The comment section is open for discussion: how did you introduce this molecule, and what did your students notice first? Our service starts from a CAS number: you name the compound, we turn it into an engraved, printable 3D model.

A ball-and-stick model of Gluconic Acid with each element symbol recessed into its atom sphere, generated by MolGod.org from a PubChem-computed 3D conformer (not an experimental crystal structure); atomic coordinates and connectivity are unchanged. STL mesh: 318,256 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.

Names in other languages: Gluconsäure (de); acide gluconique (fr); acido gluconico (it); Gluconzuur (nl); kwas glukonowy (pl); 葡萄糖酸 (zh).
