Study Notes
Carbohydrates Overview
- C6H12O6 represents a monosaccharide, a fundamental sugar molecule.
- Starch is digestible by humans due to enzymes that break alpha-glycosidic linkages, unlike cellulose, which contains beta-glycosidic linkages.
- Lactose is a disaccharide made of glucose and galactose joined by a glycosidic linkage.
Enzymes and Digestion
- Amylase is an enzyme capable of hydrolyzing glycosidic linkages in starch, specifically targeting alpha forms of glucose monomers.
- It cannot break down cellulose due to its different linkage type.
Classification of Carbohydrates
- The term "carbohydrate" encompasses all types of sugars including monosaccharides, disaccharides, and polysaccharides.
- Examples include glucose (a monosaccharide) and glycogen (a polysaccharide), illustrating the relationship between simple and complex carbohydrates.
