FAQ
Frequently Asked Questions
In precise terms, 'complex carbohydrate' often refers to polysaccharides (like starch), which are one type of compound sugar. 'Compound sugar' is a broader biochemical category that includes both disaccharides (e.g., sucrose) and polysaccharides.
Nutritional value depends on the source. Compound sugars in whole foods (like starch in potatoes) provide energy and nutrients. Refined compound sugars (like table sugar) offer 'empty calories'.
A compound sugar is a single, chemically bonded molecule (e.g., lactose). A mixture is just different sugar molecules physically together (e.g., honey, which contains glucose, fructose, and sucrose separately).
Digestion requires specific enzymes. Lactose intolerance, for example, is caused by a deficiency of lactase, the enzyme needed to break down the compound sugar lactose.
A carbohydrate formed by the chemical combination of two or more monosaccharide units (simple sugars).
