Determination and Correlation of d-Ribose Solubility in Twelve Pure and Four Binary Solvent Systems

, 2020
Experimental solubility data of d-ribose in four binary (2-propanol + 1-hexane, ethanol + 1-hexane, methanol + dichloromethane, and ethanol + dichloromethane) and twelve pure (1-hexane, dichloromet...

Enthalpies of combustion of d-ribose and 2-deoxy-d-ribose

The Journal of Chemical Thermodynamics, 1987
Abstract The enthalpies of combustion of the crystalline monosaccharides d -ribose (C5H10O5, cr) and 2-deoxy- d -ribose (2-deoxy- d -erythro-pentose) (C5H10O4, cr) have been determined by combustion bomb calorimetry. The following molar thermodynamic quantities are reported at T′ = 298.15 K: the standard enthalpy of combustion for d -ribose and 2 ...

Production of d -ribose by fermentation

Applied Microbiology and Biotechnology, 1997
The production of D-ribose by fermentation has received much attention lately, possibly because of the use of this pentose to synthesize antiviral and anticancer drugs. This review briefly outlines the methods that have been used to synthesize D-ribose since it was identified in yeast RNA, and focuses in particular on the latest developments in D ...

An in vitro approach to unveil the structural alterations in d-ribose induced glycated fibrinogen

Journal of Biomolecular Structure and Dynamics, 2020
Plasma proteins persistently bear non-enzymatic post-translational modifications (NEPTM) that proceeds with nucleophilic addition between free amino groups of proteins, and carbonyl group of reducing sugars.

D-ribose – An additive with caffeine

Medical Hypotheses, 2009
Caffeine acts as a stimulant, in which approximately 90% of people in the United States consume daily. Besides its beneficial effects, many individuals have experienced unpleasant reactions following the consumption of caffeine: such as insomnia, an increase in heart rate, feelings of nervousness, headaches, occasional lightheadedness, a state of ...

D-Ribose and Deoxy-D-Ribose Induce Apoptosis in Human Quiescent Peripheral Blood Mononuclear Cells

Biochemical and Biophysical Research Communications, 1994
In previous papers we reported that D(-)-ribose and 2-deoxy-D-ribose, which rank at the top among reducing sugars, kill a variety of human and animal cells and cell lines. Here we demonstrate that these two sugars induce apoptosis in human quiescent peripheral blood mononuclear cells which are relatively insensitive to apoptosis. Apoptosis was assessed

Addition of 2-deoxy-d-ribose to clinically used alginate dressings stimulates angiogenesis and accelerates wound healing in diabetic rats

Journal of Biomaterials Applications, 2019
Following recent work from our group on a small ribose-derived sugar 2-deoxy-d-ribose which stimulates angiogenesis in a chick chorionic allantoic membrane bioassay and in skin wounds in healthy rats, we tested the effect of this sugar when added to a ...

Prevalence of auto-antibodies against D-ribose-glycated-hemoglobin in diabetes mellitus.

Glycobiology, 2019
Glycation of biological macromolecules, due to hyperglycemia, promotes the formation of advanced glycation end products (AGEs). It is accelerated in diabetic patients and is responsible for the pathophysiology and progression of diabetes.

p‐Toluate der D‐Ribose

Journal für Praktische Chemie, 1962
AbstractDurch partielle Acylierung der D‐Ribose‐mercaptale mit p‐Toluylsäurechlorid in Pyridin werden 5‐p‐Toluyl‐D‐ribose‐mercaptale dargestellt. Daraus erhält man durch Abspalten von Mercaptan die 5‐p‐Toluyl‐D‐ribose. Bei der vollständigen Acylierung der D‐Ribose‐mercaptale entstehen 2,3,4,5‐Tetra‐p‐toluyl‐D‐ribose‐mercaptale, die bei der Abspaltung ...

d-ribose in glycation and protein aggregation

Biochimica et Biophysica Acta (BBA) - General Subjects, 2012
D-ribose is a naturally occurring pentose monosaccharide present in all living cells and their microenvironments and is a key component of numerous biomolecules involved in many important metabolic pathways. It also participates in the glycation of proteins producing advanced glycation end products (AGEs) that lead to cell dysfunction and death.
