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.
