Study Notes
Glycomics
- Glycomics is the scientific study of glycomes
- A glycome is the complete set of carbohydrates and carbohydrate-associated molecules that cells produce.
Configuration
- Configuration is the three-dimensional arrangement of atoms in a molecule.
- Configuration can only be changed by breaking chemical bonds.
Conformation
- Conformation is the spatial arrangement of atoms in a molecule.
- Conformation can be altered by rotating single bonds.
- Examples of conformations include cis-trans and E/Z isomers.
Asymmetric or Chiral Carbon
- An asymmetric or chiral carbon is a carbon atom bonded to four distinct atoms or groups of atoms.
- Chiral molecules can exist as enantiomers, which are mirror images of each other.
Fischer Projection
- A Fischer projection is a two-dimensional representation of a three-dimensional organic molecule.
- The horizontal lines in a Fischer projection represent bonds that point towards the viewer.
- The vertical lines in a Fischer projection represent bonds that point away from the viewer.
Haworth Projection
- A Haworth projection is a method used to depict the three-dimensional structure of a cyclic sugar molecule.
- It shows the cyclic sugar molecule as a flat ring, with the substituents on the ring pointing either above or below the plane.
