Because enzymes can only catalyse reactions of molecules with specific shapes. Glucose, galactose and fructose all have different shapes, so they need to undergo different reactions in order to be metabolised.
All sugars are converted to fructose phosphate before metabolism begins. This happens to fructose by phosphorylating it directly, to glucose by phosphorylating glucose, then converting the glucose phosphate to fructose phosphate, and to galactose by converting the galactose to glucose.
Glucose, Galactose, & Fructose
Carbohydrates are made up of molecules called monosaccharides, which are simple sugars such as glucose, fructose, and galactose. Monosaccharides can link together to form larger carbohydrates like disaccharides (e.g. sucrose, lactose) and polysaccharides (e.g. starch, glycogen, cellulose).
glucose, fructose. and galactose! :D
The monosaccharides important in nutrition are glucose, fructose, and galactose. These carbohydrates are important as they are the simplest form of sugar that can be easily absorbed and utilized by the body for energy.
Sucrose and Lactose. Sucrose is made from glucose and fructose, and Lactose is made from glucose and galactose. Hope this helps! (:
Galactose, fructose, and glucose are all monosaccharides, or simple sugars, but they differ in their chemical structures and metabolic pathways. Galactose and glucose have similar structures, while fructose has a different structure. In terms of metabolism, galactose and glucose are primarily metabolized in the liver through the same pathway, while fructose is metabolized differently in the liver and can have different effects on the body, such as contributing to fat accumulation.

Glucose, Fructose, and Galactose are all examples of monosaccharides.
There are three monosaccharides: glucose, fructose and galactose.
The monomer of carbohydrates is monosaccharides, such as glucose, fructose, and galactose. These monosaccharides can join together through glycosidic bonds to form larger carbohydrate molecules like disaccharides and polysaccharides.
its a simple sugar such as glucose, galactose and fructose. hope this helped :)
The three simple sugars absorbed into the bloodstream are glucose, fructose, and galactose.
glucose, fructose, sucroseI believe glucose, galactose, and fructose are the three most common.
