Explanation:
Detailed explanation-1: -HFCS is derived from corn starch. Starch itself is a chain of glucose (a simple sugar) molecules joined together. When corn starch is broken down into individual glucose molecules, the end product is corn syrup, which is essentially 100% glucose.
Detailed explanation-2: -Compared to sugar, corn syrup is made up of polysaccharides. Since corn syrup came from starch (which is a complex sugar), its chemical bonding is different and includes more molecules of sugar.
Detailed explanation-3: -Polysaccharides are very large polymers composed of tens to thousands of monosaccharides joined together by glycosidic linkages. The three most abundant polysaccharides are starch, glycogen, and cellulose.
