Water


  • Adhesion - Adhesion is an attraction between different substances(not alike)
  • Cohesion - Cohesion is an attraction between substances of the same kind(are alike)
  • Polarity - The polarity of water enables it to allow other substances to dissolve in water (polar/non-polar molecules)
  • Polar Molecules - Polar molecules are molecules that dissolve well in water.
  • Non-polar Molecules - Non-polar molecules are molecules that do not dissolve well in water
  • Storage of heat (Heat Storage) - This is the ability to control temperatures enables cells to maintain a constant internal temperature when the external temperature changes drastically.
  • Ph - The Ph scale measures the concentration of hydrogen ions in solutions on a scale between 0-14. 0-6 being more acidic containing things like lemons and vinegar. 7 being evened out which is milk. And 8-14 being the more basic which contains items like Hand Soap and Household Ammonia


General Info, Macromolecules

Macromolecules are large molecules that is made with carbon(C), other atoms used are Hydrogen, Nitrogen,Oxygen,Phosphorus, Sulfur etc. Note: in order to be organic the molecule needs to be made of carbon.



There are 4 types of macromolecules

  • Carbohydrates
  • Proteins
  • Lipids( other known as fats)
  • Nucleic Acids


Carbohydrates

  • Carbohydrates are organic compounds made of Hydrogen(H), Carbon(C), and Oxygen(O). These are the key source of energy for the body and is found in most foods.
  • There are 4 types of carbohydrates. there is Monosaccharides, Disaccharides, Oligosaccharides, and Polysaccharides

Proteins

  • Proteins are chains of amino acids folded into blobs with special shapes. Each shape of a protein has its own lock and key and function. A protein cannot work without its shape and if proteins didn't have the shapes it does we would die.

Nucleic Acids

  • There are 3 types of nucleic acids and those are, DNA RNA and ATP.

Lipids

  • Lipids is another name for fats. The purpose for lipids or fats is to make up cell membranes, and to give the body long term energy.
