What are isomers?
Same chemical formulas, different structures
what is Lactose?
Disaccarides: Glactose in ß(1 -> 4) linkage with glucose
What are the main function of Polysaccarides?
-Energy storage
- structure (e.g. cellulose, chitin)
Generelles über Lipids?
- insouble in water
- souble in organic sovents and other lipids
- very important biomolecules
4 Main classes of Lipids?
- Triacylglycerols (TAGs) - storage lipides (non-polar, also known as triglycerides)
- Phosphoacylglycerols - Membrane structural lipids (polar)
- Sphingolipids - Membrane structural lipides (polar)
- Nonsaponifiable lipids
Function of Lipids?
- Storage molecules for energy
- Structural components of cellular membrane
- protective molecules (waxes)
- homones and vitamines
- intracellular messengers
- pigments
