Introduction

Protein (1838), large number of organic

compounds that make up living organisms

and are essential to their functioning.Proteins are now as the predominant

ingredients of cells, making up more than

50 percent of the dry weight of animals.

The word protein is coined from the Greek

proteios, orprimary.

Protein molecules range from the long,insoluble fibres that make up connective

tissue andhair to the compact.

Soluble globules that can pass through cell

membranes and set off metabolic reactions.

They are all large molecules, ranging in

molecular weight from a few thousand to

more than a million.

They are specific for each species and for

each organ of each species.

Humans Protein

Humans have an estimated 30,000

different proteins, of which only about 2

percent have been adequately described.Proteins in the diet serve primarily to build

and maintain cells, but their chemical

breakdown also provides energy, yielding

close to the same 4 calories per gram as

do carbohydrates.

Besides their function in growth and cell

maintenance, proteins are also responsible

for muscle contraction.The digestive enzymes are proteins, as are

insulin and most other hormones. The

antibodies of the immune system are

proteins, and proteins such as hemoglobin

carry vital substances throughout the body.

Structure

Amino Acids, important class of organic

compounds that contain both the amino

(8NH2) and carboxyl (8COOH) groups. Of

these acids, 20 serve as the building blocks ofproteins.

Place of Protein Synthesis

Ribosome

On the surface of therough endoplasmic

reticulum arenumerous small, darkstructures calledribosomes.Ribosomes, which are

also found floating freein the cytoplasm, arethe sites of proteinsynthesis.
