Document Summary
Biochemistry the scientific discipline that seeks to explain life at the molecular level. Includes the structures, function and metabolism of the four major classes of biomolecules. Anabolism biosynthesis of larger, more electron-rich biomolecules (ex. Catabolism degradation (oxidation) of molecules to capture and utilize energy. Living organisms obey the laws of thermodynamics: any reversible process can proceed spontaneously in the direction that lowers the systems. Units measured in biochemistry: mega (m) - 106, kilo (k) 10 3, milli (m) 10 -3, micro (u) 10-6, nano (n) 10-9, pico (p) 10-12, femto (f) 10-15 se2 - aqueous chemistry. Geometry of carbon bonding: sp3 orbital tetrahedral (109. 5 degrees, sp2 orbital planar (120 degrees, rotations about covalent bonds defines conformation, changes in configuration requires the making or breaking of covalent bonds. Molecular representations: alanine: structure, ball and stick, space fill (vdw radii) limited to electron cloud *spatial sense. *see some common functional groups in biomolecules figure 1-15.
