  1. Hello,
  2. I'm Donovan Pat
  3. and I'll be teaching you about
  4. biological macro
  5. molecules.
  6. I am currently in biology.
  7. 1 55 sec B 06,
  8. there are four main micro molecules, proteins, lipids,
  9. nucleic acids and carbohydrates.
  10. These micro molecules are fundamental to
  11. the structure and functioning of living organisms
  12. and they interact with each other to maintain life processes.
  13. Here are the four pictures of each macromolecule.
  14. Uh Obviously, they don't look anything
  15. like each other and they honestly shouldn't, they are very different new,
  16. vastly different things.
  17. The first on the list, we have the proteins,
  18. proteins are large molecules made up of amino acids that mainly consists of carbon,
  19. hydrogen, oxygen, nitrogen and sulfur.
  20. They play a crucial role in various biological processes and
  21. are involved in the functions such as structural support,
  22. enzymatic reactions.
  23. Transportation and signaling
  24. protein is a polymer and an example of this is the carrot in your nails and hair.
  25. The second is the nucleic
  26. acids. Nucleic acids are polymers that store and transmit genetic information.
  27. Uh They, there are two types of nucleic acids, DNA
  28. and R N A DNA carries the genetic instructions for
  29. the development functioning and reproduction of all living organisms.
  30. While R N A is involved in the protein
  31. ayes,
  32. nuclear acids are similar to protein. In terms of the elements present carbon,
  33. hydrogen,
  34. oxygen,
  35. nitrogen plus
  36. phosphorus.
  37. Number three, we have the carbohydrates, right. Carbohydrates also known as
  38. saccharide
  39. are composed of sugar molecules.
  40. They serve as a major source of energy that
  41. can be found in various forms such as sugar,
  42. starches and fibers.
  43. Carbohydrates also have structural roles in certain organisms.
  44. Carbohydrates contain only carbon,
  45. hydrogen
  46. and oxygen
  47. and a
  48. polymers
  49. last but not least.
  50. The lipids, lipids are diverse molecules that include fats, oils,
  51. waxes and steroids.
  52. They are in sole
  53. water means that they don't not
  54. in water but are sole
  55. and nonpolar solvents.
  56. Lipids are important for energy storage insulation,
  57. cushioning and deformation of the cell membrane.
  58. They also serve as signaling molecules and
  59. play a role in various physiological processes.
  60. They, they contain,
  61. excuse me, they consist of oxygen, carbon and hydrogen
  62. as well
  63. are polymers as well.
  64. That is my presentation. I thank you for your time today.
  65. And this please don't forget that these
  66. functions highlight the central roles of biological
  67. macro molecules and maintain the structure function
  68. and overall well-being of living organisms.
  69. I
  70. and
  71. Patton. Thank you for your time.
