How important are
PROTEINS?

The hemoglobin protein carries oxygen in
your blood to every part of your body.
Hemoglobin is an iron-containing
pigment that makes the blood red.
Proteins like alpha-keratin and keratin
forms your hair and fingernails, and
also it is a major component of feathers,
wool, claws, scales, horns and hooves.

Receptor proteins stud the outside of your
cells and transmit signals to partner proteins
on the inside of the cells.
Muscle proteins called actin and
myosin enable all muscular
movement-from blinking to breathing
to other movements.

Antibodies are considered proteins
that help defend your body against
foreign invaders such as bacteria and
viruses.
Ion channel proteins control brain
signalling by allowing small
molecules into and out of the nerve
cells.

Huge clusters of proteins including initiator
proteins form molecular machines that do
your cell’s heavy work, such as copying genes
during cell division and making new proteins.
Enzymes in your saliva, stomach
and small intestine are proteins
that help you digest food.

Proteins may generally have GLOBULAR or
FIBROUS structure depending on its particular
role in the bodily functions.
