    Study Notes

    Carbohydrate Functions

    • Primary function of carbohydrates when consumed: provide energy for the body
    • Carbohydrates derived from plants and some microorganisms

    Categories of Carbohydrates

    • Polysaccharides include both homo- (e.g., starch, cellulose) and heteropolysaccharides (e.g., glycoproteins, proteoglycans)

    Structural Differences

    • Monosaccharides: single sugar molecules (e.g., glucose, fructose)
    • Disaccharides: composed of two monosaccharides (e.g., sucrose, lactose)

    Biological Importance

    • Carbohydrates are the body's primary source of energy
    • Essential for brain function, physical activity, and maintenance of body functions

    Digestion and Absorption

    • Carbohydrates broken down into monosaccharides in the digestive system
    • Monosaccharides absorbed into the bloodstream and transported to cells for energy production

    Energy Production

    • Glucose: primary carbohydrate used by the body to produce energy
    • Excess glucose converted to glycogen for storage or fat for energy storage

    Classification of Carbohydrates

    • Simple carbohydrates: monosaccharides and disaccharides, often referred to as sugars
    • Complex carbohydrates: polysaccharides, including starch, cellulose, and glycogen

    Biological Roles

    • Carbohydrates act as 'road signs' for molecules on cell surfaces, guiding interactions
    • ABO blood markers on red blood cells consist of carbohydrates
    • Non-digestible carbohydrates play a role in promoting gut health and immune system function

    Biomedical Importance

    • Understanding carbohydrate structure and properties is crucial for developing treatments for diseases associated with carbohydrates, such as diabetes and cardiovascular disease
    • Carbohydrates combine with lipids to form glycolipids, important in cell signaling and membrane structure
