...Rémy Perez; Serge Aron ABSTRACT Over recent decades, increasing attention has been paid to how low-molecular-weight molecules affect thermal tolerance in animals. Although the disaccharide sugar trehalose is known to serve as a thermal protectant in unicellular organisms, nothing is known about its...

..., humans on high sugar diets become dependent on consuming high sugar foods ( Avena, 2007 ). As natural fruits, albeit less sweet than grapes, are at times present on the islands, future work should further investigate the diet composition of grape-fed and non-fed iguanas to determine whether additional...

...Nicolette Cocco; John I. Glendinning SUMMARY Manduca sexta caterpillars are unusual because they exhibit strong peripheral gustatory responses to sugars, but nevertheless fail to show immediate appetitive responses to them. We hypothesized that the primary function of the peripheral gustatory...

... with sucrose, glucose, fructose, maltose, myo-inositol and 20 common amino acids. In electrophysiological recordings from nine sensilla, responses were obtained to certain compounds tested at 100 mmol l −1 , and the response spectra differed from broad to narrow. The four sugars excited the same receptor...
