Proteins are basically of two pairs
simple proteins and conjugate proteins
now simple proteins are basically made
up of amino acids an example of this
would be histone proteins Histone is a
protein on which your DNA or
double-stranded DNA is wrapped around
and is kept inside a set the next type
of protein is conjugate protein and I
say conjugate it a complex
it means mixture of two different things
conjugate protein is basically made up
of a protein part that is an amino acid
plus a non  protein part that is a
prosthetic group and in say prosthetic
group it means a helping an example of
conjugate proteins would be lipoproteins
or nuclear proteins now conjugate
proteins are further divided into four
different types of proteins and those
four different types of proteins are
structural proteins structural protein
an example could be keratin that is
present inside head-on the protein from
which your hair is made yes the same
keratin that gives a shiny texture to
your hair the next type of protein is
defense a protein an example of
defensive protein would be antibodies
immunoglobulins fighter cells all those
human cells of our body that fight
whenever an infection gains entry into
your body are nothing but defensive
protein and that top most would be
antibodies IgG IgA and pigments against
and body means against organism next
type of protein is transport protein and
classy example of transport proteins
would be hemoglobin by H now been able
you take an oxygen inside your body this
oxygen cannot travel all what happens is
your RBC's are present upon the artisans
there is a molecule called as hemoglobin
which sets on the our bases and upon
hemoglobin oxygen sets this three
together in a tribe travel wherever they
have to travel and oxygen is strong
at that place where oxygen is required
and RBC's and hemoglobin get back to
their position
so basically hemoglobin is a transport
protein for oxygen the last type of
protein is contractile protein when I
say contraction and relaxation this all
is associated with your muscles or
moment now myosin is a protein that is
present inside muscles which helps in
relaxation and contraction of your
muscles
types of proteins are simple protein and
complex proteins simple proteins are
made up of amino acids for an example of
this is histone proteins on which DNA is
wrapped the next type of protein is
conjugate protein or even sick complex
proteins or combination proteins now
this conjugate proteins are made up of
two protein as well as non protein part
the protein part is basically amino acid
and the non protein part is prosthetic
group or helping hand now this a minus a
plus through trust a table together
forms the viable protein an example of
this this proteins plus lipids that
forms lipoproteins and this lipoproteins
are nothing but helps in signaling or
inside or outside entry or exit of
biomolecules inside set
types of conjugate proteins are
structural proteins transfer proteins
defensive proteins and contractile
proteins an example of structural
protein is keratin that is present
inside cell transfer proteins made
include HP or hemoglobin that help to
transport oxygen along with RBC's their
trial travels together for oxygen supply
in body
another type of protein is defense a
protein an example of this is antibodies
or AV or immunoglobulins now this
antibody protect human beings against
infections of certain diseases the last
type of proteins are contractile
proteins contact eye proteins an example
of this is myosin that is present inside
muscle which hits in contraction and
relaxation of muscles so students in
this part of the chapter we have studied
about various types of proteins and how
they function together I hope you all
are clear about various types of
proteins and their function
thank you
