Valenzuela,; López,; Depix,; Mancilla,; Kettlun,; Catalán,; Chiong Lay, Mario; Garrido,; Traverso Cori, A. (1989)1. 1. Apyrase (ATP: diphosphohydrolase) has been found in the microsomal fraction of rat salivary gland, mammary gland and uterus. 2. 2. This enzyme, already described in plant tissues, is mainly present as a soluble ...

Valenzuela,; Guerra,; Garrido, (1987)
-
Valenzuela,; Basualto,; Sapag,; Tapia, (Elsevier Ltd, 1997)A membrane transport process is described. The process was developed for use in the recovery of copper from nitric acid leach residual solutions. The flux and the extraction extent of copper with 5-dodecylsalicylaldoxime ...
