Cbz-Cl (18.5 μl,0.155 mmol) in diethyl ether (0.2 ml) was dropped to a solution of (R)-1(36.4 mg, 0.129 mmol) in 10% aqueous Na2CO3(1.8 ml) at 0°C,and stirred for 5 h. The reaction mixture was acidified with 10% citric acid,extracted with CHCl3(10mlX3). The organic layer ...
Acetic acid is widely used in manufacturing either as starting material or solvent; in the food industry, dilute solutions are used for preparation and preservation. Because acetic acid is a "weak acid", it is effective as buffer at pH 4.75 " 1. This buffer can be prepared by titrat...
maintained in position throughout the 90 min of addition. The stirred reaction mixture is thengradually allowed to warm to room temperature over the next 8–10 hr. The reaction iscarefully quenched at room temperature by dropwise addition of 1 : 1 water : acetic acid (ca.20 mL) with stirri...
Acetic acid causes toxicity by coagulative necrosis; that is, the acid denatures all tissue proteins to form an acid proteinate. As a result, both structural and enzymatic proteins are denatured and cell lysis is blocked. Therefore, cell morphology is not greatly interrupted. In addition, an es...

Aldehyde Dehydrogenase is an NADP-dependent enzyme that catalyzes the oxidation of aldehydes to corresponding carboxylic acids.
Acetic acid or ethanoic acid is a colourless liquid organic compound. When acetic acid is dissolved in water, it is termed glacial acetic acid. It is a weak acid since the solution dissociates only slightly.
(HeLa/mClover3-mAID-Lem2) expressing an mClover3-mAid-Lem2 protein as the sole Lem2 protein (Supplementary Fig.5a). WB of lysates of cells treated with indole-3-acetic acid (IAA) for 60 min revealed that Lem2 was almost completely lost (Supplementary Fig.5b), consistent with the ...
[translate] aIn contrast,the ionization of acetic acid is only 1 to 3 depending on the concentration of the acid,so it is a week acid 相反,乙酸的电离只是1到3根据酸的集中,因此它是星期酸[translate]
Incorporation of 14C-thymidine (DNA), 14C- uridine (RNA), 14C -L-amino acid mixture (protein), 14C-Acetic acid (fatty acid) and 14C-acetyl-glucosamine (peptidoglycan) was determined in cells treated with 8x MIC of evybactin (grey bars). Ciprofloxacin (8x MIC), rifampicin (8x MIC), ...
