immediate
source of
energy of
cells
- Polysaccharides:
energy storage
compunds or
structural role

- Generalities:
- Carbon
- Bonding
- Carbon can
bond with as
many as four
other atoms
- Carbon can
bond with itself
to form both
chains and rings
- Differences in the
carbon skeleton =
different chemical
properties
- Hydrophobic:
repels water.
Hydrophilic:
attracts water.
- Carbon can
bond with as
many as four
other atoms
- Bonding
- Biomolecules
- Carbohydrates,

folding; bonding
and hydrophobic
interactions.
- Quaternary:
Polypeptide>1
- Primary:
sequence
