    Study Notes

    Carbohydrates

    • Disaccharides are composed of two sugar molecules bonded together through a glycosidic linkage.
    • An example of a homopolysaccharide is cellulose, which is a complex carbohydrate composed of many glucose molecules bonded together.
    • Polysaccharides have functional significance in providing energy storage and structural support in cells.
    • Reducing sugars, such as glucose, have a free aldehyde or ketone group, allowing them to act as reducing agents.
    • Oligosaccharides, consisting of 2-10 sugar molecules, play a significant role in cell-cell recognition, immune response, and protein targeting.
