Periodate oxidation and the shapes of glycosaminoglycuronans in solution.
1. It is proposed that periodate oxidation of glycol groups in the repeating units of polysaccharide molecules can be used to probe differences in polymer shapes in solution. 2. Measurement of second-order rate constants (k2) of periodate-glycol reactions may be compared between polymers and relevant monomers, to assess perturbations due to polymer configuration. 3. Factors effecting the measur...

متن کاملCatalytic-Spectrophotometric Determination of Trace Amounts of Manganese(II) by Catalysis of the Oxidation of Ferroin with Periodate
A catalytic spectrophotometric method for determination of ultra-trace quantities of manganese(II) id described. The method is based on the catalytic effect of manganese(II) on the oxidation reaction of ferroin by potassium periodate in acidic media. The reaction is monitored spectrophotometrically at 510 nm by a slope method and Mn(II) is determinable in the range of 1-1000ngmL-1</sup...
متن کاملGlucose Influence on Copper Ion-Dependent Oxidation of Low Density Lipoprotein
Background: It is well established that oxidative modification of low density lipoprotein (LDL) plays a causal role in human atherogenesis and the risk of atherosclerosis is increased in patients with diabetes mellitus. We examined the in vitro effect of glucose on native and glycated LDL oxidation using copper ion dependent oxidation system. Methods: In this study, LDL was isolated from plasma...
متن کاملPatterns of Molecular Weight Downshifts during Ripening'
Avocado (Persea americana) fruit experience a rapid and extensive loss of firmness during ripening. In this study, we examined whether the chelator solubility and molecular weight of avocado polyuronides paralleled the accumulation of polygalacturonase (PC) activity and loss in fruit firmness. Polyuronides were derived from ethanolic precipitates of avocado mesocarp prepared using a procedure t...
