Study Notes

Macromolecules

  • Organic molecules divide into four categories: carbohydrates, lipids, proteins, and nucleic acids
  • Each of the four types of macromolecules are made of smaller components called monomers
  • The composition of the macromolecules helps determine their function

Lipids

  • Lipids are made up of carbon, oxygen, and hydrogen, and sometimes other elements
  • Functions include: long-term fat and energy storage, protecting organs, and making up biological membranes

Proteins

  • Proteins are made of amino acid sequences with an amino group, carboxyl group, and R group
  • Functions include: providing cell structure, sending chemical signals, and speeding up chemical reactions

Nucleic Acids

  • Nucleic acids are made of a series of nucleotides containing a sugar backbone, a nitrogenous base, and a phosphate group
  • Nucleic acids store and pass on genetic information

Proteins Function Question

  • The varying order of amino acids in a protein code allows proteins to serve many different functions in the body
