| 설명 | 혈압, pH 등과 같이 생체의 기능 및 상태를 안정시키고자 하는 작용 : pH 7인 순수한 물에서 소량의 산 또는 알칼리를 가하면 그 양에 따라 물의 pH가 뚜렷하게 변한다. 그러나 약한 산과 그 염의 혼합용액, 또는 약한 산기와 그 염의 혼합용액으로 이루어지는 계에서는 약간의 산 또는 알칼리를 가해도 완충작용 때문에 pH는 거의 변하지 않는다. 예를 들어, 약한 산과 그 염의 혼합용액으로 이루어지는 계系에 산을 가했을 때를 생각하면, 산에 의해서 가해진 수소이온 H+은 약한 산이온과 결합하여 비해리인 산이 되어 pH가 변하지 않는다. 또 알칼리를 가했을 때는 가해진 수산이온 OH－이 H+과 결합하여 물을 만들고, 부족한 H+은 비해리 약한 산의 해리에 의해서 보충되므로써 역시 pH는 변하지 않는다. |

buffer
| 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) |
| buffered | <pharmacology> Refers to pills coated with a special substance that neutralises stomach acid. Drugs are buffered to reduce stomach upset or increase absorption by the intestines. (09 Oct 1997) |
| buffered crystalline penicillin G | Crystalline potassium penicillin G or crystalline sodium penicillin G buffered with not less than 4% and not more than 5% of sodium citrate. (05 Mar 2000) |
| buffers | Chemical systems that prevent change in the concentration of another chemical substance, e.g. Proton donor and acceptor systems serve as buffers preventing marked changes in hydrogen ion concentration (pH). (12 Dec 1998) |
| 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) |

| secondary buffer | See: Hamburger's law. (05 Mar 2000) |
| 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) |

| buffer action |
an action that tends to stabilize an inanimate system or a body function or state, such as pH, blood pressure, [Ca 2 + ], etc.; most commonly used to denote the stabilization of pH by acid-base buffers (tampon a.).

| buffer |
A storage device, or area on a storage device, which holds data temporarily, until needed for processing or printing. A buffer can also be used to aid communication between two devices with very different processing speeds (such as two modems, or the CPU and the printer).
