The final hydrolysis product is the [Ru(terpy)(bipy)(OH)] + complex, since amides, being poor 蟺-acceptor ligands, are rapidly released from the coordination sphere of ruthenium(II).doi:10.1016/S0277-5387(96)00447-0Florencia Fagalde
In this model, an enzymatic lysine attacks C4 of uridine to form a Schiff base RNA–protein conjugate. Sequenced RT-PCR products from the fern Ceratopteris richardii indicate U-to-C base edits do not preserve proteinaceous crosslinks in planta. Hydrolysis of a protonated Schiff base conjugate ...
The characteristic reaction of covalent amides ishydrolysis(a chemical reaction with water), by which they are converted to acids and amines; this reaction ordinarily is slow unless it is catalyzed by a strong acid, an alkali, or an enzyme. Amides also can be dehydrated to nitriles. ...
Sarcosine also results from the action of acids or alkalies on caffeine and theobromine (Vol.VI); and w. Paulmann (Arch. Pharm., 232, 601) recommends the hydrolysis of caffeine as the best method for the preparation of sarcosine, the yield being 60% of the theoretical. [References]https:...

of the carboxyl unit was not formally quantified due to interference from other acidic species. However, comparisons with close structural analogues such as glutamine suggest the value lies in the range 2.1-2.5[13]Theanine is stable under acidic conditions but undergoes base hydrolysis to yield ...
Hydrolysis of amides to carboxylic acids catalyzed by Nb2O5 The high catalytic performance observed was attributed mainly to the facile activation of the carbonyl bond by Lewis acid sites that function even in the presence of basic inhibitors (NH3 and H2O). The catalytic studies showed the ......
alanines.ALSO:Beta-alanine or substituted beta-alanines are prepared by the hydrolysis with an acid or base of linear polymers of acrylamide or substituted acrylamides which have been prepared by the polymerization of the amide monomer under anhydrous conditions in the presence of a strongly basic...
