β-glucose

Overview

β-Glucose refers to the β-anomeric form of glucose, a six-carbon monosaccharide and one of the principal simple sugars in biology. In aqueous solution, glucose exists in equilibrium between cyclic α- and β-anomeric forms, with the β form often predominating. As a central carbohydrate, glucose is fundamental to cellular energy metabolism, serving as a major substrate for glycolysis, oxidative phosphorylation, glycogen synthesis, and multiple biosynthetic pathways.

In biomedical research, β-glucose is usually discussed in the broader context of glucose biology rather than as a distinct therapeutic agent. It is clinically important as a circulating metabolite, a marker of glycemic status, and a substrate or trigger in assays, biosensors, and metabolic engineering systems. Its behavior is relevant to type 2 diabetes, diabetic ketoacidosis, chronic kidney disease, ischemic stroke, liver-related outcomes, and cancer metabolism, as well as to glucose-responsive biomaterials and Glucose oxidase-based diagnostic platforms.

Focus of Latest Publications

Recent publications have examined glucose in multiple clinical contexts, with particular emphasis on its role in diabetes-related complications and glucose homeostasis. In patients with diabetic foot ulcers, blood glucose levels and glycemic control markers predicted mortality risk, though Wagner classification of ulcer severity did not. Glucose regulation has also been investigated in type 1 diabetes, where the timing of resistance exercise affected acute and nocturnal postprandial glucose responses. In pregnancy, fasting, first-hour, and second-hour glucose values from oral glucose tolerance testing were evaluated for their predictive strength in identifying fetal macrosomia in non-diabetic women. Postprandial glucose dynamics in obesity showed substantial individual variation, with elevated and delayed glucose peaks strongly associated with markers of insulin resistance, hepatic dysfunction, and altered metabolic phenotypes.

A major focus has been the development of advanced glucose biosensing and monitoring platforms for clinical applications. Researchers created enzymatic electrochemical biosensors incorporating glucose oxidase immobilized on nanoparticle-decorated carbon nanotubes and biocomposite films, achieving rapid detection with sensitivity comparable to clinical devices and sustained stability over weeks. Enzyme-free approaches were also explored, including a glucose-responsive wearable microneedle patch readable via ultrasound that delivered stable glucose measurements for up to 56 days. Time-gated fluorescent aptamer sensors utilizing europium-based FRET systems and aptamer-based electrochemical platforms were developed for continuous glucose monitoring in complex biological samples, including cerebrospinal fluid in neurocritical care and neonatal point-of-care testing.

Glucose-responsive smart materials have emerged as tools for managing diabetic complications. Researchers developed self-reinforcing hydrogels based on polysaccharide networks that scavenge excess glucose from the wound microenvironment while adapting their mechanical properties accordingly, promoting macrophage reprogramming and angiogenesis in diabetic wounds. Glucose oxidase-loaded nanoreactors were designed to exploit hyperglycemic microenvironments as a therapeutic trigger, converting excess glucose into gluconic acid and hydrogen peroxide to generate reactive oxygen species for antibacterial effects while intelligently switching to a healing-promoting catalase mode as glucose was depleted.

Finally, glucose was identified as a relevant metabolic marker across diverse disease states. In congenital hypothyroidism, β-glucose was among seven common differential serum metabolites that enabled an optimized neural network diagnostic model with 89.4% prediction accuracy. In acute lymphoblastic leukemia, glucose consumption was linked to chemotherapy resistance through active mTOR signaling and pyrimidine synthesis dependencies. In a natural product study, glucose as a structural component of Codonopsis pilosula polysaccharides contributed to anti-aging effects through modulation of gut microbiota and JAK2-STAT3 signaling.
