●The Boyer text denes Biochemistry as the study of life (structure, informaon and energy) at
the molecular level.
●Biochemistry examines the chemistry of living organisms.
●The major biomolecules are:
○nucleic acids- informaon
●4 big elements: hydrogen, carbon, nitrogen and oxygen- they make up most molecules.
●Carbon is the atom involved in all organic molecules- this is because it can make four bounds
that are not all in the same plane.
●The more electronegave an atom is, the closer the electrons will be to that element. Oxygen is
a very electronegave atom.
●Sharing electrons= covalent bond (water has a polar covalent bond)
