The present paper deals with the kinetics and mechanism of homogeneously Ir(III) chloride catalyzed oxidation of D-mannitol by chloramine-T [CAT] in perchloric acid medium in the temperature range of 30 to 45 0C. The reaction is carried out in the presence of mercuric acetate as a scavenger for chloride ion. The experimental results show first order kinetics with respect to the oxidant [CAT] an...

We studied the ability of Cryptococcus neoformans to produce the hexitol D-mannitol in vitro and in rabbits with experimental meningitis. Twelve of twelve human isolates of C. neoformans produced D-mannitol in yeast nitrogen base plus 1% glucose and released D-mannitol into the medium. In a pilot study, pooled cerebrospinal fluid (CSF) from cortisone-treated rabbits given 3 x 10(7) C. neoforman...

Bacteriol. 89:326-330. 1965.-A sugar alcohol was isolated from the conidia of Aspergillus oryzae and identified as d-mannitol. Two types of d-mannitol dehydrogenases, nicotinamide adenine dinucleotide phospha...

2,5-Anhydro-D-mannitol (100 to 200 mg/kg) decreased blood glucose by 17 to 58% in fasting mice, rats, streptozotocin-diabetic mice, and genetically diabetic db/db mice. Serum lactate in rats was elevated 56% by 2,5-anhydro-D-mannitol, but this could be prevented by dichloroacetate (200 mg/kg) or thiamin (200 mg/kg). In hepatocytes from fasted rats, 1 mM 2,5-anhydro-D-mannitol inhibited gluconeo...

Mannitol dehydrogenase, NADP specific (EC 1.1.1.138), was purified from mycelium of Aspergillus parasiticus (1-11-105 Whl). The enzyme had a molecular weight of 1.4 X 10(5) and was composed of four subunits of apparently equal size. The substrate specificity was limited to D-mannitol, D-glucitol, D-arabinitol, 1-deoxy-D-mannitol, and 1-deoxy-D-glucitol. Zinc ion was a powerful inhibitor of the ...

In vitro regeneration of four cultivars of carnation namely ‘Nelson’, ‘Impulse’, ‘Sagres’ and ‘Spitit’ through somatic embryogenesis was studied. MS culture medium was supplemented with 30 gl-1 sucrose, 2 mgl-1 2,4-D and 0.2 mgl-1 BA and used for embryogenic callus formation. Somatic embryos were formed when embryogenic callus was transferred to MS medium without growth regulators containing 30...

This study investigates the effect of gluconate, a carboxylate anion, and three uncharged hexitols, D-sorbitol, d-mannitol D-galactitol on solubility C-S-H. Thermodynamic modeling is used to determine kind amount Ca-organic-silicate-OH complexes that potentially form in conditions studied. All organics with calcium hydroxide. In addition, heteropolynuclear calcium, hydroxide silicate are observ...
