Hemoglobin 1HHO Ribbon

<h2>3D Printed NFT of Oxygenated Hemoglobin (Hb) created from x-ray crystallography dataset 1HHO</h2>

This scientific model visualizes the Dimer structure of Hemoglobin coloring the alpha-helices of both Alpha-chains light red and the beta-chain helices soft-red. The coils of the protein are colored white. Inside each Alpha and Beta chain is a HEME Group, a pyloric ring of carbon-nitrogen atoms. Locked into the core of each HEME group is a single Iron atom. Bond to the open side of the Iron atom are Oxygen molecules (red). These bonds are stabilized by a series of Histidine residues throughout the protein (colored by to see their Nitrogen atoms) that lock onto the Oxygen molecules further stabilizing Oxygen binding. 

When unlocked, this NFT contains a coupon code for an 8 cm 3D print of Oxygenated Hemoglobin Hb Ribbon 1HHO (purchase price of $500). If the NFT is resold, 50% of the 10% commission will go towards funding the NFT's Coupon. If the final trading commission increases the Coupon's value to > $2000, this 3D Print will be a "ONE-OF-A-KIND" work of art, printed at the largest possible size, 20 cm. If the coupon is redeemed before the Coupon reaches $2000, the 3D Design will be released to our website and new NFT 3D Digital Models will be made available.
