Study Notes
Carbohydrate Classifications
- Carbohydrates with more than ten monosaccharide units are classified as polysaccharides.
- Disaccharides contain two monosaccharide units, which can be identical or different.
- Monosaccharides are categorized based on their carbon atom number: trioses (3), tetroses (4), pentoses (5), hexoses (6), and so forth.
Specific Monosaccharides
- Glucose is a hexose sugar and is characterized as an aldose due to its aldehyde group.
- D-galactose and D-glucose are structural isomers, differing in arrangement around specific carbon atoms.
- Epimers are a type of stereoisomer that differ in configuration at a single carbon atom.
Functions of Carbohydrates
- Cellulose, a polysaccharide, primarily serves structural support in plant cell walls.
- Carbohydrates play essential roles in energy storage, cellular recognition, and as a component of nucleic acids, where they provide structural integrity.
- Ribose serves as a crucial component of nucleotides, forming the backbone of RNA.
- Carbohydrates are the main source of energy for living cells.
Isomerism and Structural Features
- Aldoses have an aldehyde group, distinguishing them from ketoses, which contain a ketone group.
- The arrangement of hydrogen (H) and hydroxyl (OH) groups around the penultimate carbon defines a type of stereoisomerism.
- The orientation of H and OH around the anomeric carbon leads to anomerism, a specific type of stereoisomerism.
Biochemical Roles
- Pentoses, such as ribose and deoxyribose, are vital for nucleic acid formation and function in the human body.
- D and L designations of monosaccharides are based on the orientation of the hydroxyl group on the penultimate carbon.
- Carbohydrates contribute significantly to various biological functions, including energy provision, structural roles, and participation in cellular signaling pathways.
