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
Glucose, fructose, and galactose are all examples of six-carbon sugars. They all have the same chemical formula, but have different structural formulas.
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.
The three simple sugars absorbed into the bloodstream are glucose, fructose, and galactose.
