Dextrose, Fructose, or Sucrose

quote:

post workout we want to create an insulin spike and replete muscle gylcogen. Sucrose is part fructose and part dextrose. its good in a sense since it is a high gi carb but the fructose goes straight to be converted into liver glycogen. Liver glycogen doesnt do much and when its full, what ever else you eat with fructose will be spilled ove . Dextrose on the other hands is proccesed in the muscles and coverted to muscle gylcogen.

What we call sugar, the chemist knows as sucrose, one of the family of sugars otherwise known as saccharides in the grouping called carbohydrates. Carbohydrates, as the name implies, contain carbon and hydrogen plus oxygen in the same ratio as in water. The saccharides is a large family with the general formula CnH2nOn. The simplest of the sugars is glucose, C6H12O6, although its physical chemistry is not that simple because it occurs in two distinct forms which affect some of its properties. Sucrose, C12H22O11, is a disaccharide, a condensation molecule made up of two glucose molecules [less a water molecule to make the chemistry work].
Dextrose is commonly used as a sweetener, a source of rapidly absorbed energy and a carrier in water soluble medications. Dextrose is approximately 70% as sweet as sucrose.
