Study Notes
Carbohydrates and Glycosidic Bonds
- Glycosidic bonds link carbohydrate molecules by forming when a hydroxyl group reacts with the carbonyl group of another carbohydrate.
Classes of Enzymes
-
Oxidoreductase:
- Hydroxylase: Adds hydroxyl (-OH) groups.
- Oxidase: Uses O2 as an electron or hydrogen acceptor.
- Reductase: Facilitates reduction reactions.
- Dehydrogenase: Involved in oxidation processes.
-
Transferase:
- Kinase: Transfers phosphate groups.
- Carboxylase: Adds carboxyl (-COOH) groups.
-
Hydrolase:
- Catalyzes hydrolysis, breaking chemical bonds during food digestion.
-
Lyase:
- Cleaves chemical bonds without hydrolysis.
- Decarboxylase: Removes carboxyl (-COOH) groups.
Isomers and Epimers
- Glucose consists of four asymmetric carbon atoms.
- Isomers like fructose, glucose, mannose, and galactose differ in configuration around one specific carbon atom and are classified as epimers.
Disaccharides
- Reducing Disaccharides:
- These have a free anomeric carbon in the second sugar unit, enabling them to act as reducing sugars.
