Hydrolysis of Methylglucosides
Nature, 1954IN the course of a study of the mechanisms involved in the solvolytic reactions of glycosides, we have investigated the position of bond fission occurring in the hydrolysis of α- and β-D-methylglucosides. The reactions were carried out in water enriched in oxygen-18, and the methanol produced was isolated by fractional distillation in an efficient ...

Hydrolysis of Benzothiadiazines
Journal of Pharmaceutical Sciences, 1971The hydrolysis of hydrochlorothiazide and two other hydrothiazides was studied as a function of pH. Reversible kinetics were observed for the hydrolytic reaction, and a bell-shaped pH-rate profile was obtained. The equilibrium constant, however, was relatively independent of hydrogen-ion concentration.

Hydrolysis of cyclodisilazanes
Organometallics, 1989Abstract Unhindered N,N′-diphenyltetramethylcyclodisilazane readily undergoes hydrolysis in the presence of catalytic amounts of acid or base. Under base conditions an intermediate diaminodisiloxane may be isolated. The more sterically congested hexaphenylcyclodisilazane is resistant to acid hydrolysis but is readily hydrolyzed in the presence of base.

Experientia, 1973
Thermal polymerization of aspartic acid produces a polysuccinimide (I), a chain of aspartoyl residues. An investigation was made of the alkaline hydrolysis of the imide rings of (I) which converts the polyimide to a polypeptide. The alkaline hydrolysis of polyimides can be expected to be kinetically complex due to increasing negative charge generated ...

Journal of Pharmaceutical Sciences, 1964
Data are presented for the hydrolytic degradation of idoxuridine (5-iodo-2′-deoxyuridine) in aqueous solution over a wide range of hydrogen ion concentration (pH 1.3 to 12.0). The over-all reaction rate was experimentally equal to k 1 [ H + ] [ H + ] + K a + k 2 K a K a + [ H + ] + k 3 K ...

This chapter covers enzyme classes that catalyse hydrolysis reactions using water to break carbon heteroatom bonds, including lipases, esterases, amidases, proteases, epoxide hydrolases, nitrilases, nitrile hydratases, dehalogenases and sulfatases. Each of the enzyme classes above is discussed in more detail in a separate section.
