| buffer | <biochemistry, chemistry> A system that acts to minimise the change in concentration of a specific chemical species in solution against addition or depletion of this species. PH buffers: weak acids or weak bases in aqueous solution. The working range is given by pKa +/ 1. Metal ion buffers: a metal ion chelator for example EDTA, partially saturated by the metal ion acts, as a buffer for the metal ion. (18 Nov 1997) |
|---|---|
| buffer capacity | <chemistry> The ability of a buffer solution to absorb added alkali or acid while maintaining the solution's pH. (09 Oct 1997) |
| buffer index | The power of a substance in solution to absorb acid or alkali without change in pH; this is highest at a pH value equal to the pKa value of the acid of the buffer pair. See: buffer capacity. Synonym: buffer index. (05 Mar 2000) |
| buffer pair | An acid and its conjugate base (anion). (05 Mar 2000) |
| buffer value | The power of a substance in solution to absorb acid or alkali without change in pH; this is highest at a pH value equal to the pKa value of the acid of the buffer pair. See: buffer capacity. Synonym: buffer index. (05 Mar 2000) |
| buffer value of the blood | The ability of the blood to compensate for additions of acid or alkali without disturbance of the pH. (05 Mar 2000) |
| buffer zone | <ecology> An area of land separating two distinct land uses that acts to soften or mitigate the effects of one land use on the other. (09 Oct 1997) |
| riparian buffer | Riparian areas that are managed to protect the aquatic and riparian ecosystem. A riparian buffer protects water quality and temperature, habitat along the banks, upland habitat for aquatic and riparian species, and some or all of the floodplain. (05 Dec 1998) |
| dipolar buffer | Buffer whose structure can include opposite charges. Synonym: dipolar buffer. (05 Mar 2000) |
| zwitterionic buffer | Buffer whose structure can include opposite charges. Synonym: dipolar buffer. (05 Mar 2000) |
| CS2 secondary alkylsulfohydrolase | <enzyme> From comamonas terrigena Registry number: EC 3.1.6.- Synonym: cs2 sa sulfohydrolase (26 Jun 1999) |
| protein structure, secondary | The stage in the development of protein structure in which regular hydrogen-bond interactions within contiguous stretches of polypeptide chain give rise to alpha helices and beta sheets. This is the first folding level of protein building. (12 Dec 1998) |
| secondary | Second or inferior in order of time, place or importance, derived from or consequent to a primary event or thing. Origin: L. Secundarius, secundus = second (18 Nov 1997) |
| secondary abdominal pregnancy | A condition in which the embryo or foetus continues to grow in the abdominal cavity after its expulsion from the fallopian tube or other seat of its primary development. Synonym: abdominocyesis. (05 Mar 2000) |
| secondary adhesion | Delayed closure of two granulating surfaces. Synonym: secondary adhesion, secondary union. (05 Mar 2000) |
