Protiens are the basis of life, they can cntrolmany things, from your appearance to the possibility for you to reproduce.
They serve as enzymatic catalysts, are used as
transport molecules (hemoglobin transports oxygen) and storage molecules (iron is stored
in the liver as a complex with the protein ferritin); they are used in movement (proteins
are the major component of muscles); they are needed for mechanical support (skin and
bone contain collagen-a fibrous protein); they mediate cell responses (rhodopsin is a
protein in the eye which is used for vision); antibody proteins are needed for immune
protection; control of growth and cell differentiation uses proteins (hormones). These
are just a few examples of the many, many functions of proteins.

protiens are the links of the basic structure of the body .they form the basis for the enzymes which help in the digestion .they constitute the major part of the DNA or RNA.so in short there wont be you and me with out protiens.

Proteins have many functions. They serve as enzymatic catalysts, are used as transport molecules (hemoglobin transports oxygen) and storage molecules (iron is stored in the liver as a complex with the protein ferritin); they are used in movement (proteins are the major component of muscles); they are needed for mechanical support (skin and bone contain collagen-a fibrous protein); they mediate cell responses (rhodopsin is a protein in the eye which is used for vision); antibody proteins are needed for immune protection; control of growth and cell differentiation uses proteins (hormones).

Proteins are a broad class of biomolecules as are lipids, nucleic acids, carbohydrates, etc... They have inumerable functions including structure of cells and organelles, signaling molecules in biochemical pathways, or enzymatic activity.

Protein are the body builders...We need protein to grow and for repairs. Proteins are used to make our body cells. Specifically, they are used in the formation of new protoplasm. Antibodies, enzymes and hormones are also made of proteins. Finally, proteins provide us with energy.

Proteins are the functional system of body, we classified them in 8 major group:
Enzymes
Structural proteins
Hormones
Receptors
Transporters
Contractible proteins
Anti bidy
Regulatory proteins
