  • Amino Acids

  • Biosynthesis


Introduction l.jpg
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, or “primary.”

  • Protein molecules range from the long, insoluble fibres that make up connective tissue and hair to the compact.

  • Soluble globules that can pass through cell membranes and set off metabolic reactions.

  • 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 from a few thousand to more than a million. 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 l.jpg
Structure from a few thousand to more than a million.

  • 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 of proteins.

Ribosome from a few thousand to more than a million.

On the surface of the rough endoplasmic reticulum are numerous small, dark structures called ribosomes. Ribosomes, which are also found floating free in the cytoplasm, are the sites of protein synthesis.
