    One- to three-day-old infants who sucked to obtain flavored water revealed a precisely graded tongue movement which was sensitive to the gustatory properties of the flavored water. Stronger concentrations of sucrose and glucose elicited movements of greater amplitude than did weaker concentrations; sucrose was effective at lower concentrations than was glucose. These results correspond well with the relative sweetness adults attribute to these solutions in psychophysical studies.

    Sugars as Energy Storage Molecules

    Sugar (a simple carbohydrate) metabolism (chemical reactions) is a classic example of the many cellular processes that use and produce energy. Living things consume sugar as a major energy source because sugar molecules have considerable energy stored within their bonds. Consumed carbohydrates have their origins in photosynthesizing organisms like plants. During photosynthesis, plants use the energy of sunlight to convert carbon dioxide gas into sugar molecules, like glucose. Because this...

    Glucose Transporters

    Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
    Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:
