D-Glucose. A primary source of energy for living organisms. It is naturally occurring and is found in fruits and other parts of plants in its free state. It is used therapeutically in fluid and nutrient replacement.
The simple sugar made by the body from carbohydrates.
A six-carbon monosaccharide sugar (hexose), with the chemical formula C6H1206, occurring free in plant and animal tissues and formed by the hydrolysis of starch and glycogen. Also known as dextrose, grape sugar and blood sugar.
A 6-carbon sugar found widely in nature and 74% as sweet as Sucrose.
Alternative name for glucose. Commercially the term ‘glucose’ is often used to mean com syrup (a mixture of glucose with other sugars and dextrins) and pure glucose is called dextrose.
A 6-carbon simple sugar. It is also a reducing sugar.
A simple sugar; form in which carbohydrates are transported in the blood and transported in tissues; other sugars are converted into glucose by enzymes in the body before they can be used as an energy source.
A type of sugar; the chief source of energy for living organisms.
A prime fuel for the generation of energy by organisms. It is broken down (to obtain energy) via a metabolic process called glycolysis. Glucose is a hexose, a sugar possessing six carbon atoms in its molecule. The six carbon atoms are connected to each other to form a closed ring structure known as a hexose (6) ring. Animal cells store glucose in the form of glycogen (sometimes called animal starch), a large branched polymer of glucose units. Plant cells store glucose in the form of starch, a large polymer of glucose units.
Yeasts and bacteria store glucose in the form of dextran. a polymer of glucose units. The difference between the forms of storage glucose is (1) in the size (molecular weight) of the final polymer formed, (2) in the type of linkages that connect the single glucose units together in the branched molecule, and (3) in the degree of branching which occurs in the polymer. Note that a glucose polymer does not consist of just a single long straight chain. The backbone chain has other polymer chains branching off of it. The whole molecule may be visualized as looking somewhat like a tree without the trunk. The other very abundant polymer formed by glucose units is structural in nature and is called cellulose. It is the most abundant cell wall and structural polysaccharide in the plant world. Hence, glucose is used not only as an energy source, but also as a structural material.
A simple sugar produced by the digestion of starch and sucrose. Glucose is the main source of energy for the body’s cells.
Glucose or corn sugar is produced from cornstarch and is often sold blended with sucrose. It is about three-fourths as sweet as sucrose.
A monosaccharide (dextrose, com sugar). Found in sweet fruits and some vegetables.
A simple sugar found in some fruit, but also broken down from white sugar or carbohydrate and absorbed into the body or secreted by the kidneys.
A sugar used extensively by the body as a source of energy. All the starch and sucrose present in the food is broken down to glucose, and consuming it directly confers no special advantage.
The simplest form of sugar in which a carbohydrate is assimilated in the body; blood sugar.
Simple sugar molecule and the primary source of energy for the brain.
Synonymous with glucose.
A six-carbon monosaccharide. The preferred metabolic fuel for most cell types, particularly those of the CNS.
Glucose is a 6-carbon monosacharride (a hexose) found abundantly in many various forms in a wide array of foods. Free glucose is found in many fruits, honey, corn syrup, sports drinks, and a large assortment of other foods. Glucose is also a component of most other carbohydrates including, but not limited to, starch, sucrose, lactose, and maltose. Any foods rich in these nutrients ultimately provide the body with significant amounts of glucose. Furthermore, the other primary dietary monosaccharides fructose and galactose are ultimately converted to glucose or glucose derivatives after absorption. Since all carbohydrates can be converted into glucose, it is an extremely important nutrient physiologically. Glucose, however, can be made available for the body from more than just dietary carbohydrates. Many amino acids, glycerol, and pyruvic and lactic acids can be used to produce glucose through gluconeogenesis.
A type of sugar that forms the body’s main form of energy (also called dextrose). People with diabetes mellitus lack the hormone insulin needed to convert the sugar to usable form; as a result, glucose builds up in the blood, leading to hyperglycemia and perhaps diabetic coma. People under insulin treatment can sometimes have too little glucose in the blood, a condition called hypoglycemia or insulin shock. To prevent either of these extremes, many people with diabetes carefully monitor the levels of glucose in their blood, often using a home medical test.
Simple sugar, also called glucose, used in intravenous feeding; table sugar (sucrose) is broken down to dextrose in the body.
Simple sugar that is the major energy source in the body. Ingested in certain foods, esp. fruits, and produced by the breakdown of other carbohydrates, glucose is absorbed into the blood from the intestines; excess amounts are stored in the form of glycogen, chiefly in the liver. Determination of glucose levels in the blood is important in the diagnosis of many disorders, including diabetes mellitus. Pharmaceutical preparations of glucose (e.g., dextrose) are widely used in medicine.
A natural sugar found in cerebrospinal fluid. CSF levels are measured to detect abnormal conditions of the spinal cord and brain. Levels are decreased in meningitis.
A type of sugar or glucose. Dextrose is added to processed foods to make them sweeter and as a preservative to prevent bacterial growth. A high proportion of sugar in the diet provides the body with few nutrients and unnecessary energy that may be stored as fat. Pharmaceutical preparations of dextrose are used in hospitals to provide nutrition via intravenous infusions.
A simple sugar or monosaccharide that is the body’s chief source of energy. Most carbohydrates are broken down by digestive enzymes into glucose. After digestion, glucose passes into the bloodstream where it is used by cells for energy and growth. In order for glucose to enter most cells, insulin (a hormone produced by the pancreas) must be present. However, in a person with type 1 diabetes, the pancreas produces insufficient insulin. Consequently, glucose accumulates in the blood, flows into the urine, and passes out of the body. People with type 1 diabetes require daily insulin injections.
A simple sugar containing six carbon atoms (a hexose). Glucose is an important source of energy in the body and the sole source of energy for the brain. Free glucose is not found in many foods (grapes are an exception); however, glucose is one of the constituents of both sucrose and starch, both of which yield glucose after digestion. Glucose is stored in the body in the form of glycogen. The concentration of glucose in the blood is maintained at around 5 mmol/l by a variety of hormones, principally insulin and glucagon. If the blood-glucose concentration falls below this level neurological and other symptoms may result Conversely, if the blood glucose level is raised above its normal level, to 10 mmol/l, the condition of hyperglycemia develops. This is a symptom of diabetes mellitus.
Another name for purified grape sugar or glucose. A common constituent of intravenous fluids.
Glucose, also known as dextrose, is the form of sugar found in honey, grapes and some other fruits. All the sugars and starches we eat are converted into glucose in the small intestine before being absorbed. It is the form of sugar circulating in the bloodstream.
A simple sugar that is the major provider of energy for the body’s cells.
Simplest form of sugar. Carbohydrate is broken down into glucose before being absorbed into the bloodstream and taken to the cells for the production of energy.
The most elementary configuration of a saccharide, predominantly discovered within the bloodstream, and actively employed by cellular entities as a source of energy.
A simple sugar that is the building block of starch. In the small intestine, digestive enzymes break down large molecules of complex carbohydrates (starch) into smaller molecules. These and simple carbohydrates (sugars) are then broken into simpler monosaccharides (glucose, fructose, and galactose) to be absorbed into the bloodstream where they are available as a source of energy to the cells. Glucose is the most critical of these monosaccharides, because it is the source of fuel used by the brain, central nervous system, and lungs. It is so important to your body that if your diet doesn’t provide enough carbohydrates to supply glucose, the brain will signal a shortage, and muscle tissue will be broken down to supply the shortfall. That means you lose body muscle (not fat) to feed your brain.
A sweetening agent derived from corn, with caloric content. Dextrose, similar to corn syrup, adds to the common practice in America of consuming over 200 calories worth of sweeteners derived from corn on a daily basis.
Glucose is a type of uncomplicated sugar. It appears in the form of white, crystalline particles and offers a mildly sweet flavor. Glucose is a component of everyday cane sugar and is present in starch. When carbohydrates are broken down during digestion, they transform into glucose, which is subsequently absorbed by the bloodstream. After a meal, the glucose level in the bloodstream increases, but it typically normalizes after an hour, depending on the individual and the nature of the meal consumed.
A mechanism through which a white blood cell surrounds and consumes waste material and microorganisms, effectively eliminating them from the bloodstream.
Glucose is a basic sugar, or monosaccharide, that is naturally found in fruits and is also a result of starch and sucrose digestion. It’s the primary energy source for the body and is transported to all body tissues through the bloodstream. The phrase “blood sugar” is used to denote the levels of glucose present in the blood.
The concentration of glucose in the blood is typically maintained at a fairly steady state due to the effects of several hormones, particularly insulin, glucagon, adrenaline, corticosteroid hormones, and growth hormone. Hyperglycemia, an unusually high blood glucose level, may result in glucose being excreted in the urine. Conversely, an abnormally low blood glucose level is referred to as hypoglycemia.
