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…
