d glucose and fructose relationship help

I am not sure what you are asking, but D-glucose and D-fructose are constitutional isomers. home / study / science / chemistry / chemistry questions and answers / What Is The Relationship Between D-glucose And. Glucose and galactose are aldohexoses (C-1 is an aldehyde). so there are 2[ math]^4[/math] (16) different optical isomers (eight different names, D- and L-.

Glycogen If glucose enters your cells and is not immediately needed for energy, glucose molecules can be linked together in branching chains and stored as a form of starch called glycogen. When energy is needed, glycogen can be broken down into glucose.

Your muscles store glycogen for their own use.

However, your liver can store large amounts of glucose as glycogen, and if your blood glucose level gets too low, glycogen can be broken down into glucose and released into your blood for use by other tissues. Gluconeogenesis When your blood glucose level falls too low, your liver can also make glucose from non-glucose sources and then secrete the glucose into your blood for other tissues to use for energy.

This process is called gluconeogenesis. Nitrogen can be removed from amino acids and the residual molecules converted into glucose. Lactic acid from anaerobic glycolysis in muscles and glycerol from triglyceride breakdown in fatty tissues may also be recycled to your liver for glucose production. Pentose Phosphate Pathway The pentose phosphate pathway converts a six-carbon glucose molecule into a five-carbon pentose sugar called ribose that is used as a component of the nucleic acids present in your genetic material.

During metabolism of glucose to ribose, a molecule called NADPH is also produced and used in the process of making cholesterol and fatty acids. Connective Tissue Sugars Glucose can be modified and used in the formation of protein-sugar complexes that help to make up your connective tissues and lubricating fluids. Examples include chondroitin, keratin and hyaluronate in your cartilage, bone, heart valves, skin and eyes.

Fructose Fructose is metabolized primarily in your liver. Unlike fructose, insulin is secreted primarily in response to elevated blood concentrations of glucose, and insulin facilitates the entry of glucose into cells.

Fructose Fructose is a sugar found naturally in many fruits and vegetables, and added to various beverages such as soda and fruit-flavored drinks.

However, it is very different from other sugars because it has a different metabolic pathway and is not the preferred energy source for muscles or the brain.

Fructose is only metabolized in the liver and relies on fructokinase to initiate metabolism. It is also more lipogenic, or fat-producing, than glucose. Unlike glucose, too, it does not cause insulin to be released or stimulate production of leptin, a key hormone for regulating energy intake and expenditure. These factors raise concerns about chronically high intakes of dietary fructose, because it appears to behave more like fat in the body than like other carbohydrates.

Sucrose Sucrose is commonly known as table sugar, and is obtained from sugar cane or sugar beets.

Sucrose vs Glucose vs Fructose: What's the Difference?

Fruits and vegetables also naturally contain sucrose. When sucrose is consumed, the enzyme beta-fructosidase separates sucrose into its individual sugar units of glucose and fructose.

Both sugars are then taken up by their specific transport mechanisms. The body responds to the glucose content of the meal in its usual manner; however, fructose uptake occurs at the same time.
