Digestion and the Glands

The Digestive System.

Disgestion breaks down large molecules into smallewr molecules.

  • many molecules in our food are polymers
  • polymers = large, complex molecules composed of long chains of momoers (e.g monosaccharide or aminoacid.
  • Proteins and some carbohydrates are polymers. 
  • In carbohydrates the momomers are called monosaccharides ( containing carbon hydrogren and oxygen).
  • proteins the monomers are amino acids ( containing carbon hydrogen oxygen and nitrogen)
  • Polymers in our food are insoluble, so cant be directly absorbed in to our blood stream
