Morphological, Thermal and Physicochemical Properties of Starches from Squash (Cucurbita maxima) and Pumpkin (Cucurbita moschata)
The properties of starches isolated from two squash cultivars (Cucurbita maxima) were studied and compared with those of two pumpkin cultivars (Cucurbita moschata) and one normal potato cultivar. The amylose content of pumpkin and squash starches ranged from 16.18% to 21.29%. The pumpkin and squash starches appeared as a mixture of spherical, polyhedral and dome shaped granules. The pumpkin and...
متن کاملApplication of Asian pumpkin (Cucurbita ficifolia) serine proteinase for production of biologically active peptides from casein.
The main objective of this study was to determine potential application of a serine proteinase derived from Asian pumpkin for obtaining biologically active peptides from casein. The course of casein hydrolysis by three doses of the enzyme (50, 150, 300 U/mg of protein) was monitored for 24 hours by the determinations of: hydrolysis degree DH (%), free amino group content (μmole Gly/g), RP HPLC ...
متن کاملLectins in castor bean seedlings.
The amounts of the two lectins (ricin and Ricinus communis agglutinin) in tissues of castor bean seedlings were followed during germination and early growth. For measurement, lectins in extracts were separately eluted from Sepharose columns; an antibody to the agglutinin was also used to detect the lectins by immunodiffusion. The endosperm of the dry seed contains 3.5 mg total lectin (5.6% of t...
متن کاملl-Ornithine:2-Oxoacid Aminotransferase from Squash (Cucurbita pepo, L.) Cotyledons: Purification and Properties.
ORNITHINE: 2-oxoacid aminotransferase (EC 2.6.1.13) has been purified over 400-fold with a total recovery of 14% from acetone powders of cotyledons of germinating squash (Cucurbita pepo, L.) seedlings. The pH optimum of the transamination between l-ornithine and alpha-ketoglutarate is 8 and the Michaelis constants are 4.7 mm and 6.3 mm, respectively. The enzyme has a molecular weight of 48,000 ...
متن کاملChemical Characterization of a Hypoglycemic Extract from Cucurbita Ficifolia Bouche That Induces Liver Glycogen Accumulation in Diabetic Mice
BACKGROUND The aqueous extract of Cucurbita ficifolia (C. ficifolia) fruit has demonstrated hypoglycemic effect, which may be attributed to some components in the extract. However, the major secondary metabolites in this fruit have not yet been identified and little is known about its extra-pancreatic action, in particular, on liver carbohydrate metabolism. Therefore, in addition to the isolati...
