| isoelectric | Of equal electrical potential. Compare: isoelectric point. Synonym: isopotential. Isoelectric focusing, electrophoresis of small molecules or macromolecules in a pH gradient. (05 Mar 2000) |
|---|---|
| isoelectric focusing | <technique> Electrophoresis in a stabilised pH gradient. High resolution method for separating molecules, especially proteins, that carry both positive and negative charges. Molecules migrate to the pH corresponding to their isoelectric point. The gradient is produced by electrophoresis of amphiphiles, heterogenous molecules giving a continuum of isoelectric points. Resolution is determined by the number of amphiphile species and the evenness of distribution of their isoelectric points. (18 Nov 1997) |
| isoelectric line | The baseline of the electrocardiogram. (05 Mar 2000) |
| isoelectric period | The period occurring in the electrocardiogram between the end of the S wave and the beginning of the T wave during which electrical forces are acting in directions such as to neutralise each other so that there is no difference in potential under the two electrodes. (05 Mar 2000) |
| isoelectric point | <biochemistry> The pH at which a protein carries no net charge. Below the isoelectric point proteins carry a net positive charge, above it a net negative charge. Due to a preponderance of weakly acid residues in almost all proteins, they are nearly all negatively charged at neutral pH. The isoelectric point is of significance in protein purification because it is the pH at which solubility is often minimal and at which mobility in an electrofocusing system is zero (and therefore the point at which the protein will accumulate). (18 Nov 1997) |
| isoelectric zone | The range of H-ion concentration (pH) over which isoelectric precipitation occurs. (05 Mar 2000) |
| aldol condensation | Formation of an aldol (a beta-hydroxy carbonyl compound) from two carbonyl compounds; the reverse reaction is an aldol cleavage; fructose 1,6-bisphosphate aldolase catalyses such a reaction. (05 Mar 2000) |
| beta-oxidation-condensation theory | <biochemistry> That the two carbon fragments split from the fatty acid molecule by beta-oxidation are converted to acetic acid and then condensed to acetoacetic acid. (05 Mar 2000) |
| chromosome condensation | <cell biology> The tight packing of DNA into chromosomes in metaphase, in preparation for cell division. (18 Nov 1997) |
| Claisen condensation | The formation of a beta-keto ester from two esters, one of which has an alpha-hydrogen atom; malate synthase, citrate synthase, and ATP citrate lyase all catalyze such reactions. (05 Mar 2000) |
| condensation | <chemistry> The process whereby a gas becomes a liquid or a solid. A chemical reaction between two organic compounds which produces (among other things) water, ammonia, or a simple alcohol. A chemical reaction between two molecules which links them together and expels a molecule of water. For example: the joining of two amino acids by a peptide bond during the formation of a polypeptide. (05 Jan 1998) |
| condensation compound | A compound resulting from the combination of two or more simple substances, with the splitting off of some other substance, such as alcohol or water; e.g., a peptide. Compare: conjugated compound. (05 Mar 2000) |
| condensation polymer | <chemistry> The kind of polymer that is formed by the combination of monomers and the release of a small molecules at the point where monomers are joined. (05 Jan 1998) |
| dehydration-condensation reaction | The joining of two molecules to each other with the release of a water molecule in the process. Compare: hydrolysis. (09 Oct 1997) |
| fractional condensation | A lab technique used to separate the components of a vapor containing a mixture of substances. This is done by taking advantage of the fact that the different chemicals have different boiling points. The mixture undergoes repeated condensations, where the chemical with the highest boiling point condenses out of the vapor first and can be separated from the rest, then the chemical with the next highest boiling point condenses out, etc. (09 Oct 1997) |
