Amino acids

• What is an amino acid?

  The building blocks of protein that joined together to make protein molecules
• Defined the term essential aminos acid?

  means the body cannot make it themselves and must get it from food
• Explain the key term biological value?

  The number of essential amino acids the protein food contains
• There are atleast 20 amino acids
• 10 amino acids are essential for children
• Eight amino acids are essential for adults
• High biological value proteins contain or 10 essential amino acids
• Low biological value proteins are missing one or more essential amino acids
• If you eat you are more LBV protein foods together you will get all amino acids
• Children are growing so they need more essential amino acid than adults
• • Amino acids, which are sometimes referred to as the body's 'building blocks', make up proteins.
  • The human body can only produce some types of amino acids (non-essential) so we must eat the ones our bodies can't produce (essential).
• High biological value (HBV) proteins

  
  

  • Have all the essential amino acids that humans need.
  • Mostly located in animal sources (like chicken, salmon etc.)
  • Soya beans also contain HBV proteins.
• Low biological value (LBV) proteins

  
  

  • Don't contain all the essential amino acids that humans need.
  • Only located in plant-based foods.
  • E.g. cereals, pulses, nuts etc.
