1. Atividade antitríptica de proteínas em polpas e sementes de frutas tropicais
A alimentação saudável e diversificada é essencial para a manutenção da saúde física e mental, e apesar de o perfil alimentar atual valorizar a praticidade do comer, nota-se que a população está consumindo, de forma crescente, frutas, tanto na forma in natura como na forma de sucos. No entanto, o consumo de certas frutas in natura ocorre acompanha

2. Superoxide Free Radicals Are Produced in Glyoxysomes 1
The production of superoxide free radicals in pellet and supernatant fractions of glyoxysomes, specialized plant peroxisomes from watermelon (Citrullus vulgaris Schrad.) cotyledons, was investigated. Upon inhibition of the endogenous superoxide dismutase, xanthine, and hypoxanthine induced in glyoxysomal supernatants the generation of O2− radicals and this

3. Uptake of Benzyladenine by Excised Watermelon Cotyledons
The uptake of 8-[14C]N6-benzyladenine (BA) was studied in excised watermelon (Citrullus vulgaris Schrad.) cotyledons 24 hours after the start of imbibition. The passive nature of this uptake is suggested by the following evidence: (a) no sign of saturation on increasing external concentration of BA; (b) no decrease in uptake under conditions that inhibit ATP

4. Comparative Studies of Glyoxysomes from Various Fatty Seedlings 1
The separation of various organelles from cotton cotyledon (Gossypium hirsutum L.), cucumber cotyledon (Cucumis sativus L.), peanut cotyledon (Archis hypogaea L.), pine megagametophyte (Pinus ponderosa Laws), and watermelon cotyledon (Citrullus vulgaris Schrad.) by sucrose density gradient centrifugation was found to be similar to that described for castor b

5. Peroxisomal copper, zinc superoxide dismutase. Characterization of the isoenzyme from watermelon cotyledons.
The biochemical and immunochemical characterization of a superoxide dismutase (SOD, EC 1.15.1.1) from peroxisomal origin has been carried out. The enzyme is a Cu,Zn-containing SOD (CuZn-SOD) located in the matrix of peroxisomes from watermelon (Citrullus vulgaris Schrad.) cotyledons (L.M. Sandalio and L.A. del Río [1988] Plant Physiol 88: 1215-1218). The am

6. Development of Enzymes in the Cotyledons of Watermelon Seedlings 1
Changes in hypocotyl length, cotyledon weight, lipid content, chlorophyll content, and capacity for photosynthesis have been described in seedlings of Citrullus vulgaris, Schrad. (watermelon) growing at 30 C under various light treatments. Corresponding changes in the levels of 19 enzymes in the cotyledons are described, with particular emphasis on enzymes o

7. Intraorganellar Distribution of Superoxide Dismutase in Plant Peroxisomes (Glyoxysomes and Leaf Peroxisomes) 1
The intraorganellar distribution of superoxide dismutase (SOD) (EC 1.15.1.1) in two types of plant peroxisomes (glyoxysomes and leaf peroxisomes) was studied by determinations of SOD latency in intact organelles and by solubilization assays with 0.2 molar KCl. Glyoxysomes were purified from watermelon (Citrullus vulgaris Schrad.) cotyledons, and their integr
