A fructose (levulose) molecule has six carbon atoms, twelve hydrogen atoms, and six oxygen atoms which is generally found in nature, but can be produced into such sugars as hi
…gh fructose corn syrup. This is done by taking corn (usually genetically modified) and milling it into corn starch. Then by adding the enzyme a-amylase followed by the enzyme glucoamylase, this turns the starch into glucose. Glucose isomerase is then added to convert the glucose into fructose. This does not convert all glucose to fructose, however. This is where the purity of the product is noted and labeled with the percentage next to HFCS (i.e. HFCS 55 signifies 55% fructose, 45% glucose). (MORE)
