Document Summary

Directionality: all covalent bonds are in the same orientation. Hierarchy: units combine together to form polymers. Monomers and polymers: amino acid --> protein. Peptide bond: nucleotides --> nucleic acids. Water: bond polarities, net dipole, ice. 4 h bonds with adjacent water molecules. Diastereomers if formed on cell: hydrogen bond. Non-covalent interaction to lone pair in hybridized orbital. Much weaker than covalent bonds (2x length; requires less e to be broken) Entropy is high when breaking/forming (disorder is high!) Non-covalent biological molecule interaction of importance: electrostatic forces. Van der waals interactions: dipole-dipole interactions. Permanent dipoles induced: london dispersion forces. Lots of them but weaker than dipole-dipole. Bond strengths: covalent > ionic > h-bond > van der waals. The electronegativity of atoms: different atoms have different electron affinities. H
