Water

Water is a colorless and tasteless liquid found in basic organisms.

  • water freezes at 32 degrees and boils at 212 degrees Fahreinheit.
  • it has surface tention: when water molecules acttract to other water molecules (hydrogen bonds) and allow some small organisms to walk on water.
  • Water is less dense when frozen
  • not polar substances do not dissolve well in water.
  • water is polar
  • water bonds to itself (Cohesion)
  • Water bonds to other substances
  • Water pH is neutral at 7
  • Solutions with a pH less than 7 are acidic and solutions with a pH bigger than 7 are basic.


MACROMOLECULES

MACROMOLECULES

  • organic compound made of hydrogen, carbon, and oxygen
  • types of macromolecules are: carbohydrates, proteins, lipids, and neclieic acid.
  • Some examples of macromolecules are synthetic polymers (plastics, synthetic fiber, and synthetic rubber, graphen, and carbon nanotubes.


CARBOHYDRATES

  • Carbohydrates are macromolecules and are a key source of energy.
  • They can be found in bread, fruits, Vegetables, and food with added sugar.
  • They give us a source of energy and helps us with working the brain, heart and nervous, digestive and immune systems.
  • If you dont eat enough you can become fatigue or poor mental functions
  • The different types are monosaccharides, polysaccharides, oligosaccharides, and disaccharides


PROTEINS

PROTEINS

  • Proteins come in many types.
  • They are made up of high amino acids.
  • They are macromolecules.
  • Protein can be found in meat, poultry, seafood, dairy, eggs and many plant-based foods.
  • Proteins are labeled building blocks because they repair damaged tissue
  • Hair, skin, eyes, muscles and organs are all made from protein
  • protein is a major source of energy
  • Protein is involved in the creation of some hormones.
  • Enzymes are proteins that increase the rate of chemical reactions in the body.
  • Protein is a major element in transportation of certain molecules.
  • Protein forms antibodies that help prevent infection.
