Austin Biochemistry

  1. 1. Biochemistry is a branch of science concerned with chemical and physio-chemical processes and substances which occur within living organisms
  2. 2.  About 60-90 percent of an organism is water  Water is used in most reactions in the body  Water is called the universal solvent
  3. 3. Polarity Cohesiveness Adhesiveness Surface Tension
  4. 4.  Although a cell is mostly water, the rest of the cell consists mostly of carbon- based molecules  Organic chemistry is the study of carbon compounds
  5. 5.  Each type of organic molecule has a unique three-dimensional shape  The shape determines its function in an organism
  6. 6.  Large molecules are called polymers  Polymers are built from smaller molecules called monomers  Biologists call them macromolecules
  7. 7.  Proteins  Lipids  Carbohydrates  Nucleic Acids
  8. 8. There are four categories of large molecules in cells: Carbohydrates Lipids Proteins Nucleic Acids
  9. 9. Carbohydrates include: Small sugar molecules in soft drinks Long starch molecules in pasta and potatoes
  10. 10. Lipids are hydrophobic –”water fearing” Includes fats, waxes, steroids, & oils FAT MOLECULE
  11. 11. Fats store energy, which helps to insulate the body, and cushion and protect organs
  12. 12. Proteins are polymers made of monomers called amino acids All proteins are made of 20 different amino acids linked in different orders Proteins are used to build cells, act as hormones & enzymes, and do much of the work in a cell
  13. 13. Stores hereditary information Contain information for making all the body’s proteins There are two types of nucleic acids  DNA  RNA
  14. 14. Nucleic acids are polymers of nucleotides Phosphate BaseSugar Nucleotide Sugar (deoxyribose) Phosphate group Thymine (T) Nitrogenous base (A,G,C, or T)
