PROPERTY-PROPERTY RELATIONSHIPS FOR MONOSACCHARIDES

open access: yesStudia Universitatis Babes-Bolyai Chemia, 2017
The enormous diversity and complexity of polysaccharides resides in the large number of anomeric positions, diversity in the size of the rings as well as of the large number of the linkage positions of the monosaccharides.

Tandem catalysis for the production of alkyl lactates from ketohexoses at moderate temperatures [PDF]

open access: yes, 2015
Retro-aldol reactions have been implicated as the limiting steps in catalytic routes to convert biomass-derived hexoses and pentoses into valuable C_2, C_3, and C_4 products such as glycolic acid, lactic acid, 2-hydroxy-3-butenoic acid, 2,4 ...

Refolding of triose phosphate isomerase [PDF]

open access: yesBiochemical Journal, 1973
The refolding and reactivation of the glycolytic enzyme triose phosphate isomerase (EC 5.3.1.1) has been studied. The enzyme, which is a dimer, is disaggregated and unfolded in solutions of guanidinium chloride. Unfolding, followed by changes in E233, took place quite rapidly in 3m-guanidinium chloride (i.e. with a half-life of about 1 min).

Tin-containing zeolites are highly active catalysts for the isomerization of glucose in water [PDF]

open access: yes, 2010
The isomerization of glucose into fructose is a large-scale reaction for the production of high-fructose corn syrup (HFCS; reaction performed by enzyme catalysts) and recently is being considered as an intermediate step in the possible route of biomass ...

Development of a selection system for the detection of L-ribose isomerase expressing mutants of Escherichia coli [PDF]

open access: yes, 2007
L-Arabinose isomerase (E.C. 5.3.1.14) catalyzes the reversible isomerization between L-arabinose and L-ribulose and is highly selective towards L-arabinose.

Chronic glucocorticoid-rich milieu and liver dysfunction [PDF]

open access: yes, 2016
We investigated the impact of chronic hypercorticosteronemia (due to neonatal monosodium L-glutamate, MSG, and treatment) on liver oxidative stress (OS), inflammation, and carbohydrate/lipid metabolism in adult male rats.

Identification and Characterization of Pituitary Triose‐Phosphate Isomerase [PDF]

open access: yesEuropean Journal of Biochemistry, 1972
Several pituitary preparations from various species, including two purified follicle‐stimulating hormone preparations, inhibited the D‐glyceraldehyde‐3‐phosphate dehydrogenase reaction. The active factor in those preparations that caused the apparent inhibition has been identified as an enzyme, triose phosphate isomerase.

Studies of triose phosphate isomerase by hydrogen exchange [PDF]

open access: yesBiochemical Journal, 1974
The3H–H exchange of chicken muscle and rabbit muscle triose phosphate isomerases was studied. Their behaviour was mostly very similar. ‘Exchange-in’ (acquisition of radioactivity when protein was incubated in3H2O) was measured at 37°C and at pH7.5, and the rates of exchange of the native and liganded enzymes were compared.

pH-dependence of the triose phosphate isomerase reaction [PDF]

open access: yesBiochemical Journal, 1972
The pH-dependences of the kinetic parameters kcat. and Km for the triose phosphate isomerase reaction were determined in each direction. Apparent pKa values of 6.0 and 9.0 are observed in the dependences of kcat./Km. The pH-dependences of kcat. are sigmoid, with apparent pKa values of about 6.0.

Health effects of fructose and fructose-containing caloric sweeteners: where do we stand 10 years after the initial whistle blowings? [PDF]

open access: yes, 2015
Suspicion that fructose-containing caloric sweeteners (FCCS) may play a causal role in the development of metabolic diseases has elicited intense basic and clinical research over the past 10 years.
