• Proteins are vital
to any living organism
They are important
constituens of tissues and
cells of our body
• They form an important component of muscle
and other tissues and vital body fluids like
blood
• Proteins in the form
of enzymes and
hormones are
concerned with a
wide range of vital
metabolic processes
in the body
• They supply bodybuilding material
• As antibodies, they help in defending the body
against infection
• Thus they are vital to living process and carry
out a wide range of funcions essential for
sustenance of life
Resourses of PROTEINS:
lean meat
dairy products
food supplements…
