l-Alanine methyl ester hydrochloride monohydrate
The enanti-opure title compound, C(4)H(10)NO(2) (+)·Cl(-)·H(2)O, forms a two-dimensional network by inter-molecular hydrogen bonding parallel to (010). Non-merohedral twinning with a twofold rotation about the reciprocal c* axis as twin operation was taken into account during intensity integration and structure refinement. This twinning leads to alternative orientations of the stacked hydrogen-...
متن کاملThe inhibition of glutamate dehydrogenase by L-serine O-sulphate and related compounds and by photo-oxidation in the presence of Rose Bengal.
1. Glutamate dehydrogenase was inhibited by l-serine O-sulphate, beta-chloro-l-alanine, O-phospho-l-serine and beta-chloro-l-alanine methyl ester. With the exception of beta-chloro-l-alanine methyl ester which was an irreversible inhibitor, it was possible to reverse the inhibitory effects by dialysis. 2. Both NAD(+) and glutamate afford some protection against the inhibition due to the methyl ...

The conformation of the title tripeptide methyl ester hydro-chloride monohydrate, 1-[2-(methoxycarbonylmethylaminocarbonyl)pyrrolidin-1-ylcarbonyl]-2-phenylethanaminium chloride monohydrate, C(17)H(24)N(3)O(4) (+)·Cl(-)·H(2)O, is extended, but the structure cannot be classified as any typical secondary structure. Interactions through water molecules and chloride ions were formed, in addition to...
متن کاملGlycine methyl ester hydrochloride
THE TITLE COMPOUND [SYSTEMATIC NAME: (methoxy-carbonyl-meth-yl)ammonium chloride], crystallizes as a salt, C(3)H(8)NO(2) (+)·Cl(-), with the charged species inter-acting mutually via strong and highly directional N(+)-H⋯Cl(-) hydrogen bonds which lead to the formation of a supra-molecular tape running parallel to the c axis. Tapes close pack in the solid state mediated by multipoint recognition...
متن کاملN-Benzoyl-L-serine Methyl Ester Catalysed by Bromelain and by Papain ANALYSIS OF MODIFIER MECHANISMS
1. N-Benzoyl-L-serine methyl ester was synthesized and evaluated as a substrate for bromelain (EC 3.4.22.4) and for papain (EC 3.4.22.2). 2. For the bromelain-catalysed hydrolysis at pH 7.0, plots of [SO]/vi (initial substrate concn./initial velocity) versus [SO] are markedly curved, concave downwards. 3. Analysis by lattice nomography of a modifier kinetic mechanism in which the modifier is su...
