Starch Pp

  1. 1. starch Brad Ogden Brianna Sculley
  2. 2. Molecule Type: Carbohydrate Chemical Formula: C 6 H 10 O 5 Starches are polymers of glucose.
  3. 3. Starches have two parts: Amylose - C 6 H 10 O 5 arranged in a corkscrew shape
  4. 4. Amylopectin – linear glucose units with abundant branching
  5. 5. Functions of Starches - Plants <ul><li>Plant cells can change glucose (obtained from and during photosynthesis) into starch as a way for them to store sugar </li></ul><ul><li>Plants tend to store it as starch during the day and sugar at night in the green leaves </li></ul>
  6. 6. Functions in Humans/Animals <ul><li>Starches are a key source of energy in humans and animals; upon digestion, energy is directly acquired </li></ul><ul><li>Starch is found in many foods, such as pasta, cereals, breads, and potatoes. It is also found in green plants for animal consumption. </li></ul>
  7. 7. Functions of Starch in Society <ul><li>Starch is used to stiffen yarn, package products for shipping in a way that betters the environment, give a glossy look to fancy paper, and more </li></ul><ul><li>Corn starch is a common ingredient in American cooking today </li></ul>
  8. 8. Starch in Living Organisms <ul><li>Starch enters the system of an animal or human by means of food </li></ul><ul><li>Starch is found in the cells of green plants, seeds of corn, wheat, and beans, in the stems and roots of potatoes, and many other places. </li></ul><ul><li>Starch is easily digestible when cooked due to its property of gelatinization. </li></ul><ul><li>Starch is present in plants by the photosynthesis process we discussed before </li></ul>
  9. 9. The Effect <ul><li>Starch energizes humans and animals, and is the way that plants can store glucose obtained from photosynthesis </li></ul>
  10. 10. Positives <ul><li>Provides energy </li></ul><ul><li>Helps plants store sugar </li></ul><ul><li>Industrial benefits </li></ul><ul><li>Starch solutions test for iodine </li></ul>
  11. 11. Negatives <ul><li>Hard to digest when uncooked </li></ul><ul><li>Overall a very positive molecule! </li></ul>
  12. 12. Different and Related Versions <ul><li>The Human body breaks starch into glucose, providing energy. Plants store glucose as starch. </li></ul>GLUCOSE MOLECULE
  13. 13. Starch is a very beneficial and highly needed molecule that plays a vital role in the lives of humans, animals, and plants.
