Caption: Heparin binding to polylysine. Molecular graphic of heparin (red and yellow) binding to polylysine (green). Heparin is an anticoagulant produced in the human body and used as a drug to treat thrombosis. It is a strongly acidic polysaccharide that binds to basic peptides like polylysine, a polymer consisting of repeating units of the amino acid lysine. The basic amino groups on the polylysine molecule are shown by highlighting nitrogen atoms in blue. Sulphur atoms on the heparin molecule are yellow. Modelling reactions like this helps researchers understand how heparin binds to more complex proteins in the body.
