Insulin, one of the defining medical triumphs of our age.  This hormone regulates our bodies' use of sugar, and helps keep glucose levels safely in bounds.

It's also a lovely molecule.  This 3D model of human insulin shows its exquisite trefoil structure (this is the T6 form), the protein chains, zinc ions and molecular surface all drawn accurately. 

Data for this sculpture was kindly provided by Dr. G. David Smith, emeritus of the Hospital for Sick Children, Toronto, Canada.

Without illumination the crystal works best on a dark background.  It comes with clear rubber feet to avoid scratching your desk or mantel. On the left, this light base is a great way to light up your molecule! It's made of black Formica and has white LEDs that are cool, long-lasting and energy-efficient.  Bright enough for the office by day, or a brilliant nightlight. Light base – $20 I apologize, this light base is backordered to the end of March.  We won't delay the rest of your order to wait for a base (unless you ask), and when they come in we'll ship yours immediately at no extra cost. Thanks for your patience!
