The net chemical change is the addition of a water group and removal of an ammonia group, which corresponds to a +1 (0.98402) Da mass increase. Although deamidation occurs on glutamine, glycosylated asparagine and other amides, these are negligible under typical proteolysis conditions. [1]
Succinimide is an organic compound with the formula (CH 2) 2 (CO) 2 NH. This white solid is used in a variety of organic syntheses, as well as in some industrial silver plating processes.

Stain removal is the process of removing a mark or spot left by one substance on a specific surface like a fabric. A solvent or detergent is generally used to conduct ...
A common way to synthesize an NHS-activated acid is to mix NHS with the desired carboxylic acid and a small amount of an organic base in an anhydrous solvent. A coupling reagent such as dicyclohexylcarbodiimide (DCC) or 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) is then added to form a highly reactive activated acid intermediate.
A general linear imide functional group. In organic chemistry, an imide is a functional group consisting of two acyl groups bound to nitrogen. [1] The compounds are structurally related to acid anhydrides, although imides are more resistant to hydrolysis.
NBS is commercially available. It can also be synthesized in the laboratory. To do so, sodium hydroxide and bromine are added to an ice-water solution of succinimide. The NBS product precipitates and can be collected by filtration. [1] Crude NBS gives better yield in the Wohl–Ziegler reaction. In other cases, impure NBS (slightly yellow in ...
NCS is produced from succinimide by treatment with Cl + sources, such as sodium hypochlorite (bleach), and t-butylhypochlorite, and even chlorine. [2] Electron-rich arenes are readily monochlorinated by NCS. Aniline and mesitylene are converted to the respective chlorinated derivatives. [2]
