Studies on biochemical and biomedical properties of Conus betulinus venom
Marine organisms are rich sources of structurally diverse bioactive compounds. Recently, a great deal of interest has been expressed regarding marine-derived bioactive peptides because of their numerous health beneficial effects[1]. Although bio prospecting of marine organisms had yielded many bioactive peptides, pharmacologists have great passion for venoms associated peptides and their role i...
متن کاملIn vitro radical scavanging activities of Chrysaora quinquecirrha nematocyst venom.
The venom of Chrysaora quinquecirrha (sea nettle) contains several toxins that have bioactivity in mammals. In our study we aimed to extract proteins from Chrysaora quinquecirrha and to test the antioxidant potential of both crude protein and purified fractions. Proteins extracted from sea nettle nematocyst venom were purified through Sephadex G-100 column chromatography. The molecular weight o...
متن کاملBiochemical studies on inositol. III. Biosynthesis of inositol by yeast.
It is over a century since Scherer discovered in Liebig’s meat extract a hexahydroxycyclohexane which he named inositol (1). Since that time a number of similar compounds have been shown to occur in nature, and a few others have been synthesized in the laboratory. Of the nine possible stereoisomeric forms of hexahydroxycychlohexane, myo-inositol is by far the most widely distributed in nature a...
متن کاملStudies on sea snake venom
Erabutoxins a and b are neurotoxins isolated from venom of a sea snake Laticauda semifasciata (erabu-umihebi). Amino acid sequences of the toxins indicated that the toxins are members of a superfamily consisting of short and long neurotoxins and cytotoxins found in sea snakes and terrestrial snakes. The short neurotoxins to which erabutoxins belong act by blocking the nicotinic acetylcholine re...
متن کاملBiochemical Studies on Shock
During and following the production of shock by hemorrhage in the normal, suprareno-demedullated, and suprarenalectomized rat, the following significant changes in amino acid and carbohydrate metabolism have been observed. 1. In the intact, suprareno-demedullated, and suprarenalectomized rat there is a progressive rise in the whole blood and plasma amino acid nitrogen levels during and after a ...
