Chemical Composition
Function
*(CH2O)n*
Stores energy
Or C, H, and O in a 1:2:1 ratio.
Plants convert sun’s
Ex glucose: C6H12O6
energy into glucose,
5 or 6 carbon rings
which we digest and
use for energy
Monosaccharides
Disaccharides
Polysaccharides
Lipids
*Mostly C and H*
Fatty Acids -- Long chains of
carbon surrounded by
hydrogens.
Structural support
(cellulose in plants –
humans can’t break
down cellulose, but
cows can. That’s
why they eat grass
and we don’t!)
Energy Storage
Steroids
Waterproof coating
Most of the lipids we ingest
are called Triglycerides, which
is a Glycerol connected to 3
fatty acid chains.
Proteins
Nucleic Acids
Amino Acids
Nucleotides
If one fatty acid chain is
replaced by a phosphate, it
becomes a phospholipid –
essential in cell membranes!
*C, H, O, N, and sometimes S
Long chains of amino acids
which bend and fold into
complex shapes due to
hydrogen bonding – pleats,
and helixes.
C, H, O, N, and P
Cell membrane
Transportation of
substances,
Speed up reactions,
Structural support,
Hormones
DNA and RNA
Stores and transmits
genetic information
Codes for the
building of proteins
