6.1: Structure and Function- Carbohydrates
Long polymers of sugar residues are called polysaccharides and can be up to many thousands of units long. Polysaccharides are found free (not attached to other molecules) or bound to other cellular structures such as proteins.

Apr 30, 2024 · As the insulin levels drop below the normal range, glucagon from pancreatic α-cells is released, promoting a rise in blood glucose levels through glycogenolysis and gluconeogenesis. Typically, this increases glucose levels enough to last until the next meal.
Glucose - Wikipedia
In terms of chemical structure, glucose is a monosaccharide, that is, a simple sugar. Glucose contains six carbon atoms and an aldehyde group , and is therefore an aldohexose .

Feb 28, 2021 · Maltose, or malt sugar, is a disaccharide formed by a dehydration reaction between two glucose molecules. The most common disaccharide is sucrose, or table sugar, which is composed of the monomers glucose and fructose.

Jul 17, 2023 · On average, postprandial blood glucose may rise to 120 to 140 mg/dl, but the body's feedback mechanism returns the glucose to normal within 2 hours. During starvation, the liver provides glucose to the body through gluconeogenesis, synthesizing glucose from lactate and amino acids.
5.2: Carbohydrate Structures - Chemistry LibreTexts
As a child, you may have been told that sugar is bad for you. Well, that's not exactly true. Essentially, carbohydrates are made of sugar, from a single sugar molecule to thousands of sugar molecules all attached together.
Glucose | Definition, Structure, & Function | Britannica
It is found in fruits and honey and is the major free sugar circulating in the blood of higher animals. It is the source of energy in cell function, and the regulation of its metabolism is of great importance (see fermentation; gluconeogenesis).

May 12, 2023 · Carbohydrates are an important part of a nutritional diet. The healthiest sources include complex carbohydrates because of their blunted effects on blood glucose. These options include unprocessed whole grains, vegetables, fruits, and legumes.
Carbohydrate Chemistry: simple sugars, rings and glycosides
Figure 13.27 The structure of sucrose, a non-reducing sugar. Sucrose (common table sugar), is a disaccharide formed from one unit of glucose and one unit of fructose. The anomeric carbons of both glucose and fructose are involved in the glycosidic bond; sucrose; therefore, is …

Jun 28, 2021 · Inside the body, glucose is known as “blood sugar” because it is transported via the blood to all the cells of the body. Normal fasting blood sugar ranges between 70 to 99 mg/dL; two hours after eating, a normal blood sugar level is less than 140 mg/dL.
