  • what are amino acids
    building blocks of protein
  • proteins are made up of long chains of amino acids joined by peptide bonds
  • amino acids are chain-bonded
  • sequence of amino acids in a chain determines characteristics
  • 2 amino acids combined=dipeptide
    3+ amino acids combined=polypeptide
  • examples of plant-based protein
    avocado
    broccoli
    beans
    lentils
  • examples of animal-based protein
    egg
    chicken breast
    milk (calcium source)
    meat
    fish
  • importance of proteins
    growth+repair of tissue
    body structure
    enzymes
    e.g. hemoglobin
  • what is hemoglobin?
    pigment in red blood ceels
    carries oxygen
    essential protein
  • factors that affect the structure of protein
    temperature
    pH
  • when the temp of the protein is high, the structure changes, affecting the function of the protein as a consequence
  • when the pH of a protein is high, the structure changes, affecting the function of the protein as a consequence
  • what do we call smaller proteins?
    carrier proteins
  • carrier proteins need to go against the membrane
  • proteins are large organic molecules
  • when the function of a protein is affected, it becomes denatured
  • when structure of a protein is affected, the function is affected
  • when the function of a protein is affected, it changes colour, shape, taste, temp., structure, texture, etc.
