The difference between the molecular weight of sucrose and that of the sum of the molecular weights of its components (glucose and fructose ) is
Answers
Glucose, C6H12O6 a monosaccharide (or simple sugar), is the most important carbohydrate in biology. Cell use it as a source of energy and is a metabolic intermediate. In addition glucose is one of the main products of photosynthesis and starts cellular respiration in both prokaryotes and eukaryotes.
The D-glucose can exist in two forms alpha-D-glucose and beta-D-glucose. They differ only in the direction that -H and -OH groups point on carbon 1 . When alpha-glucose molecules are joined chemically to form a polymer starch is formed. When beta-glucose molecules are joined to form a polymer cellulose is formed.
Fructose, sucrose, and glucose are all natural sugars that are found in fresh fruits and vegetables as well as many commercial products.
Fructose - (C6H12O6) or fruit sugar, is a simple monosaccharide found in many plants. Most fructose can be commercially produced as a component of high fructose corn syrup. It is used in food manufacturing because it is cheap and effective as a and preservative.
Sucrose (C12H22O11) - is the organic compound commonly known as table sugar and sometimes called saccharose. The sucrose molecule is a disaccharide composed of the monosaccharides glucose and fructose.
