2. •It is the most abundant
organic molecule of the
living system.
•They occur in every part
of the cell and constitute
about 50% of the cellular
dry weight.
•It forms the fundamental
basis of structure and
functions of life.

3.  A conjugated protein is a protein
that functions in interaction with
other (non-polypeptide)
chemical groups.
 They contains non-protein
moiety known as prosthetic
group or conjugating group.
 These are attached by covalent
bond or weak interactions.

4.  Nucleoproteins
 Structually
associated with
nucleic acids either
DNA or RNA
 EXAMPLES:Riboso
mes
 Nucleosomes
 Viral nucleocapsid
proteins.

5. Mucoproteins
 A mucoprotein is
a glycoprotein compos
ed primarily
of mucopolysaccharide
s. Mucoproteins can be
found throughout the
body, including
the gastrointestinal
tract, reproductive
organs, airways, and
the synovial fluid of
the knees. They are
called mucoproteins
because the
carbohydrate quantity
is more than 4% unlike

6. 
 A phosphoprotein
is a protein that
is modified by the
attachment of either
asingle phosphate
group, or a
complex molecule s
uch as 5'-phospho-
DNA, through a
phosphate group.
 Example:caesin in
milk

 Metalloprotein is a
generic term for
a protein that
contains
a metal ion cofactor.
 Examples:Hemoglo
bin, which is the
principal oxygen-
carrier in humans,
has four subunits in
which the iron(II)
 Rubredoxin is an
electron-carrier
found in sulfur-
metabolizing bacteri
a and archaea.
