Carbohydrates

Monosaccharides
such as
glucose
are sugar monomers and can be linked to form

monosaccharides.

monomers.
are mostly neutral
hydrocarbons
and thus are

no
double bonds in the hydrocarbon chains, or
with double

Two important classes of
in cells are
phospholipids
and
steroids.
Proteins
consist of one or more
chains, which are polymers of amino acids.
An

Nucleic acid
polymers

monomers.
DNA is usually composed of two polynucleotide strands wound around each other in a
helix.
