Collagen Graphic (image) Rice University Caption A program developed at Rice University details stable forms of collagen proteins for synthesis in the lab. The ability to synthesize custom collagen could lead to better drug design and treatment of disease. The colored portion of the molecule in this illustration shows positively charged lysine and negatively charged aspartate interacting in the required axial geometry that stabilizes the triple helix.
