| lyotropic series | <chemistry> A listing of anions and cations in order of their effect on protein solubility (tendency to cause salting out). Essentially a competition between the protein and the ion for water molecules for hydration. (20 Mar 1998) |
|---|---|
| amyloid p component | Amyloid p component is a small, non-fibrillar glycoprotein found in normal serum and in all amyloid deposits. It has a pentagonal (pentaxin) structure. It acts as an acute phase protein in the mouse, modulates immunologic responses in man, inhibits elastase, and has been suggested as an indicator of liver disease. (12 Dec 1998) |
| anterior component of force | A force operating to move teeth anteriorly. (05 Mar 2000) |
| blood component removal | Any procedure in which blood is withdrawn from a donor, a portion is separated and retained and the remainder is returned to the donor. (12 Dec 1998) |
| blood component transfusion | The transfer of blood components such as erythrocytes, leukocytes, platelets, and plasma from a donor to a recipient or back to the donor. This process differs from the procedures undertaken in plasmapheresis and types of cytapheresis (plateletpheresis and leukapheresis) where, following the removal of plasma or the specific cell components, the remainder is transfused back to the donor. (12 Dec 1998) |
| p18 component, aminoacyl tRNA synthetase | <enzyme> Shares a protein motif with the beta and gamma subunits of eukaryotic elongation factor 1; amino acid sequence given in first source Registry number: EC 6.1.1.- Synonym: p18 aminoacyl-trna synthase (26 Jun 1999) |
| granular component of nucleolus | Area of nucleolus that appears granular in the electron microscope and contains 15nm diameter particles that are maturing ribosomes. In contrast to the pale staining and fibrillar areas. (18 Nov 1997) |
| component | <physiology> A constituent element or part, specifically in neurology, a series of neurons forming a functional system for conducting the afferent and efferent impulses in the somatic and splanchnic mechanisms of the body. (05 Jan 1998) |
| component A, Rab geranylgeranyl transferase | <chemical> Binds unprenylated rab1a and presents it to the catalytic component b; do not confuse with rep-1 from yeast; see also mrs6 protein Synonym: rab escort protein, rab geranylgeranyltransferase component a, rep-1 protein, rab escort protein-1, choroideraemia gene product, chm gene product, mrs6 gene product (26 Jun 1999) |
| component E, glutamate mutase | <chemical> The large subunit of glutamate mutase; from clostridium tetanomorphum; has 485 amino acid residues; mw 53,708 da; has been sequenced Synonym: mute gene product, clostridium, mute protein, clostridium (26 Jun 1999) |
| component of complement | Any one of the nine distinct protein units (designated C1 through C9 and distributed in the a, b, and g electrophoretic partitions of normal serum) that effect the immunological activities long associated with complement. C1 is a complex of three subunits: C1q, C1r, and C1s. C1q (overbar indicates "active form") activates proenzyme C1r to C1r which activates C1s to C1s (also known as C1 esterase), which converts proenzyme C2 to C2b and produces C4b from C4. C2b combines with C4b to form "classical-complement-pathway C3/C5 convertase" (also known as C3 convertase, C5 convertase, and C42). This enzyme cleaves C3 to C3a and C3b, and C5 to yield C5a and C5b, as does "alternative-complement-pathway C3/C5 convertase" (also known as proenzyme factor B, properdin factor B, C3 proactivator, and heat-labile factor). Complement factor I (also known as C3b or C3b/C4b inactivator) inactivates C3b and C4b by a different proteolytic cleavage. Several autosomal recessive disorders have been identified in which one or more of the complement components have been deficient or completely absent. (05 Mar 2000) |
| component of force | One of the factors from which a resultant force may be compounded or into which it may be resolved, one of the vectors into which a force may be resolved. (05 Mar 2000) |
| component S, glutamate mutase | <chemical> Component s of the coenzyme b12-dependent glutamate mutase from clostridium cochlearium; mw 15 kD; amino acid sequence given in first source Synonym: glms gene product, muts gene product (clostridium) (26 Jun 1999) |
| plasma thromboplastin component | <chemical> Storage-stable blood coagulation factor acting in the intrinsic pathway. Its activated form, ixa, forms a complex with factor viii and calcium on platelet factor 3 to activate factor x to xa. Deficiency of factor ix results in christmas disease (haemophilia b). Chemical name: Blood-coagulation factor IX (12 Dec 1998) |
| habitat component | <ecology> A single element (for example, velocity, depth, cover, etc.) of the habitat or environment in which a fish or other aquatic species or population may live or occur. (09 Oct 1997) |
