| plasma labile factor | <chemical> Heat- and storage-labile plasma glycoprotein which accelerates the conversion of prothrombin to thrombin in blood coagulation. Factor v accomplishes this by forming a complex with factor xa, phospholipid, and calcium (prothrombinase complex). Deficiency of factor v leads to owren's disease. Chemical name: Blood-coagulation factor V (12 Dec 1998) |
| heat-labile | Destroyed or altered by heat. (05 Mar 2000) |
| labile | 1. Gliding, moving from point to point over the surface, unstable, fluctuating. 2. <chemistry> Chemically unstable. Origin: L. Labilis = unstable, from labi = to glide (18 Nov 1997) |
