1-Aminopentane is an organic compound with the formula CH 3 (CH 2) 4 NH 2. It is used as a solvent , as a raw material in the manufacture of a variety of other compounds, including dyes, emulsifiers , and pharmaceutical products, [ 1 ] and as a flavoring agent .
The following table presents pK a values at 20 °C. Values change by about 0.01 per degree of temperature. [1] [3] Good's original 1966 paper had two older buffers (marked with italics) for comparison. In 1972 Good published a second list with three more buffers, and five more were added in 1980.
The values below are standard apparent reduction potentials (E°') for electro-biochemical half-reactions measured at 25 °C, 1 atmosphere and a pH of 7 in aqueous solution. [ 1 ] [ 2 ] The actual physiological potential depends on the ratio of the reduced ( Red ) and oxidized ( Ox ) forms according to the Nernst equation and the thermal voltage .
[1] [2] It is composed of 2.05% dextrose, 0.8% sodium citrate, 0.055% citric acid, and 0.42% sodium chloride. For usage, an equal volume of blood is gently, but thoroughly, mixed with the solution. This solution is used to study in vitro anti-inflammatory activity of crude drugs by the human red blood cell stabilization method. [3]
BSS (ophthalmic irrigation solution) (produced by Alcon) . Composition per 1 mL: sodium chloride (NaCl) 6.4 mg, potassium chloride (KCl) 0.75 mg, calcium chloride dihydrate (CaCl 2 ·2H 2 O) 0.48 mg, magnesium chloride hexahydrate (MgCl 2 •6H 2 O) 0.3 mg, sodium acetate trihydrate (C 2 H 3 NaO 2 ·3H 2 O) 3.9 mg, sodium citrate dihydrate (C 6 H 5 Na 3 O 7 ·2H 2 O) 1.7 mg, sodium hydroxide ...
McIlvaine buffer is a buffer solution composed of citric acid and disodium hydrogen phosphate, also known as citrate-phosphate buffer. It was introduced in 1921 by the United States agronomist Theodore Clinton McIlvaine (1875–1959) from West Virginia University, and it can be prepared in pH 2.2 to 8 by mixing two stock solutions.

Anaplerotic reactions, a term coined by Hans Kornberg and originating from the Greek ἀνά= 'up' and πληρόω= 'to fill', are chemical reactions that form intermediates of a metabolic pathway. Examples of such are found in the citric acid cycle (TCA cycle). In normal function of this cycle for respiration, concentrations of TCA ...
