Crystallization and preliminary X-ray diffraction studies of mandelonitrile lyase from almonds.
Single crystals of three different isoenzymes of (R)-(+) mandelonitrile lyase (hydroxynitrile lyase) from almonds (Prunus amygdalus) have been obtained by hanging drop vapor diffusion using polyethylene glycol 4000 and isopropanol as co-precipitants. The crystals belong to the monoclinic space group P2(1) with unit cell parameters a = 69.9, b = 95.1, c = 95.6 A, and beta = 118.5 degrees. A comp...
متن کاملHypoglycemic effect of Prunus amygdalus seeds in albino rabbits.
On administration of 2.5 g almond seed and its proportionate fractions, viz. 1.22 g defatted seed and 1.28 g oil to three groups of albino rabbits, they showed a definite hypoglycemic action during a two months study. The active factor seems to be a non oil fraction which is only partly soluble in ethyl ether.
متن کاملPotential Toxic Levels of Cyanide in Almonds (Prunus amygdalus), Apricot Kernels (Prunus armeniaca), and Almond Syrup
Under normal environmental conditions, many plants synthesize cyanogenic glycosides, which are able to release hydrogen cyanide upon hydrolysis. Each year, there are frequent livestock and occasional human victims of cyanogenic plants consumption. The present work aims to determine the hydrocyanic acid content in different samples of cyanogenic plants, selected from the Tunisian flora, and in t...
متن کاملRole of organic solvents on Pa-hydroxynitrile lyase interfacial activity and stability.
Catalytic activity and adsorption of Pa-hydroxynitrile lyase (Pa-Hnl) was investigated at various organic solvent/water interfaces. We focused on the role of solvent polarity in promoting activity and stability in two-phase systems, specifically for the solvents heptane, dibutyl ether (DBE), diisopropyl ether (DIPE), butylmethyl ether (BME), and methyl tert-butyl ether (MTBE). Enzyme activity t...
متن کاملMicrowave-Assisted Extraction of Phenolic Compounds from Almond Skin Byproducts (Prunus amygdalus): A Multivariate Analysis Approach.
A microwave-assisted extraction (MAE) procedure to isolate phenolic compounds from almond skin byproducts was optimized. A three-level, three-factor Box-Behnken design was used to evaluate the effect of almond skin weight, microwave power, and irradiation time on total phenolic content (TPC) and antioxidant activity (DPPH). Almond skin weight was the most important parameter in the studied resp...
