| heparin, low-molecular-weight | <chemical> Heparin fractions with a molecular weight usually between 4000 and 6000 kD. These low-molecular-weight fractions are effective antithrombotic agents. Their administration reduces the risk of haemorrhage, they have a longer half-life, and their platelet interactions are reduced in comparison to unfractionated heparin. They also provide an effective prophylaxis against postoperative major pulmonary embolism. Pharmacological action: anticoagulant, fibrinolytic agent. (12 Dec 1998) |

| heparin lyase | <enzyme> An enzyme of the isomerase class that catalyses the eliminative cleavage of polysaccharides containing 1,4-linked d-glucuronate or l-iduronate residues and 1,4-alpha-linked 2-sulfoamino-2-deoxy-6-sulfo-d-glucose residues to give oligosaccharides with terminal 4-deoxy-alpha-d-gluc-4-enuronosyl groups at their non-reducing ends. Chemical name: heparin lyase Registry number: EC 4.2.2.7 (12 Dec 1998) |
