  1. Glucose

    Glucose is a simple monosaccharide found in plants. It is one of the three dietary monosaccharides, along with fructose and galactose, that are absorbed directly into the bloodstream during digestion. An important carbohydrate in biology, cells use it as the primary source of energy and a metabolic intermediate. Glucose is one of the main products of photosynthesis and fuels for cellular respiration. Glucose exists in several different molecular structures, but all of these structures can be divided into two families of mirror-images. Only one set of these isomers exists in nature, those derived from the "right-handed form" of glucose, denoted D-glucose. D-glucose is sometimes referred to as dextrose, although the use of this name is strongly discouraged. The term dextrose is derived from dextrorotatory glucose. This name is therefore confusing when applied to the enantiomer, which rotates light in the opposite direction. Starch and cellulose are polymers derived from the dehydration of D-glucose. The other stereoisomer, called L-glucose, is hardly ever found in nature. The name "glucose" comes from the Greek word glukus, meaning "sweet". The suffix "-ose" denotes a sugar.

Examples of glucose in a Sentence

    Drinking alcohol can impair the liver's ability to release the right amount of glycogen, or stored glucose, into the blood to keep blood glucose levels stable.

  2. Sharon Horesh Bergquist:

    The cause behind these associations isn't clear, other potential biological causes could be attributed to experimental evidence linking consumption of artificial sweeteners to sugar cravings, appetite stimulation and glucose intolerance.

  3. Phil Southerland:

    I nearly put our company out of business in 2010 ... because I bought 400 blood glucose monitors, and I took about 40,000 test strips in bike boxes to the Tour of Rwanda.

  4. Danny Chou:

    We hope that smart insulin could reduce the burden for people with diabetes by decreasing the frequency of insulin injections and help them better manage blood glucose profiles to prevent short and long-term complications.

  5. Aaron White:

    Alcohol increases insulin levels and lowers blood glucose, so combining alcohol with anti-diabetic drugs that regulate glucose levels could cause an undesirable drop in blood sugar. And, over time, it could contribute to insulin insensitivity, our findings highlight a major gap in the literature.
