the beta glucose isomer is more stable than the alpha glucose isomer. As a result, beta glucose has a 64% natural abundance. Beta glucose has a specific rotation of 18.7° and a melting point of 150 °C. From the aqueous solutions, beta glucose may be crystallized as beta-glucopyranose an...
What's the difference between alpha and beta glucose? "Glucose,C6H12O6a monosaccharide (or simple sugar), is the most important carbohydrate in biology. Cell use it as a source of energy and is a metabolic intermediate. In addition glucose is one of the main products of photosynthesis and sta...
Insulin has both sympathoexcitatory and vasodilatory actions. It is unclear how these interact to affect muscular glucose uptake. The current study was designed to determine the systemic and local contributions of [alpha ]- and [beta ]-adrenergic activity to muscle glucose uptake. Forearm blood flo...

The reduction of Cr VI by α- d-glucose and β- d-glucose was studied in dimethyl sulfoxide in the presence of pyridinium p-toluensulfonate, a medium where mutarotation is slower than the redox reaction. The two anomers reduce Cr VI by formation of an intermediate Cr VI ester precursor of...
Most vesicles were double positive for pHluorin and PC2, indicating the localization of the biosensor in glucagon-containing granules (Fig. 1b). Figure 1 Analysis of glucagon release from single alpha cells by TIRF microscopy. (a) Structure of the glucagon release biosensor. The rat glucagon ...

The eryth- rocyte/brain glucose transporter (GLUT1) may adopt two channel transmembrane alpha/beta structure. J Mol Modeling 1996;2:27- 45.Ducarme, P., Rahman, M., Lins, L. & Brasseur, R. (1996) The erythrocyte/brain glucose transporter (GLUT1) may adopt a two-channel transmembrane ...
a Immediately after 16.7 mM glucose FLIM imaging, cells are fixed to preserve their shape and structure and then incubated with anti-glucagon and anti-insulin antibodies which in turn recognize α (red) and β -cells (green). b Comparison of 2.2 and 16.7 mM FLIM images with immunoflu...
Glucose inhibition of glucagon secretion from rat alpha-cells is mediated by GABA released from neighboring beta-cells. The GABA(A) receptor antagonist SR95531 was used to investigate the effects of endogenous GABA (released from beta-cells) on pancreatic islet hormone ... A Wendt,B Birnir,K ...
