What are proteins?

  1. 1. Proteins By Eric Ittah
  2. 2. What are proteins? Proteins are the building blocks of life. They are vital for the growth of cells and tissue repair. They are instrumental in everything that an organism does.
  3. 3. Functions of Proteins •Offer structural support •Helps in storage •Helps in transportation •Helps in intercellular signaling •Aid in movement •Helps in metabolism •Provides defense against foreign materials
  4. 4. Do you know???? Humans have tens of thousands of different proteins, each with their own structure and function. They are the most complex molecules known till now.
  5. 5. Basics of proteins •Proteins have a three dimensional shape •Protein polymers are constructed from amino acids. •Protein polymers are called polypeptides
  6. 6. Structure of Proteins The function of proteins depends on its structure. The function depends on its ability to recognize and bind to some other molecule.
  7. 7. Levels of protein structure There are four levels of protein structure 1. Primary 2. Secondary 3. Tertiary 4. Quarternary
  8. 8. Primary structure level The primary structure level of a protein is its unique sequence of amino acid. This structure is generally determined by inherited genetic information
  9. 9. Secondary structure level The secondary structure level of protein is the result of hydrogen bonds at regular intervals along the polypeptide backbone.
  10. 10. Tertiary structure level Tertiary structure level of a protein depends on a number of interactions among the different groups and the polypeptide group.
  11. 11. Quarternary structure level Quarternary structure results from the combination of two or more polypeptide subunits.
