Study Notes
Aldose-Ketose Isomers
- Aldose-ketose isomers are compounds with the same molecular formula, carbon skeleton, and substituent group position but differ in their functional groups (aldehyde or ketone).
- Examples include glycosides such as nucleosides (ribose or deoxyribose + nitrogenous base) and cardiac glycoside (sugar + steroid).
Disaccharides
- Disaccharides can be classified into two types: reducing and non-reducing.
- Reducing disaccharides have a free anomeric carbon that can be involved in oxidation-reduction reactions.
- Non-reducing disaccharides lack a free anomeric carbon as both anomeric carbons are involved in the glycosidic bond.
Anomeric Carbon
- The anomeric carbon of a sugar can be linked to the anomeric carbon of another sugar, forming a disaccharide.
- In a reducing disaccharide, one anomeric carbon remains free, allowing it to be oxidized.
- In a non-reducing disaccharide, both anomeric carbons are linked, preventing oxidation.
Hyaluronic Acid and Dermatan Sulfate
- Hyaluronic acid is a major component of synovial fluid, contributing to its lubricating properties.
- Dermatan sulfate is a glycosaminoglycan found in connective tissue.
- Replacement of hyaluronic acid with dermatan sulfate in synovial fluid reduces lubrication efficiency..
Hyaluronidase Enzyme
- Hyaluronidase is an enzyme that hydrolyzes hyaluronic acid in connective tissue.
- This enzyme is also known as the spreading factor because it can break down hyaluronic acid, increasing the permeability of tissues.
