Salivary amylase acts on starch to produce
maltose
Pepsin in stomach’s gastric juices acts on
protein to form peptides
Pancreatic amylase digests starch


Trypsin & chymotrypsin digests protein
Lipase digests fats



Mitochondria use glucose to produce a
constant supply of ATP for the cell
Essential fatty acids like Ω6 (linoleic acid) form
plasma membranes
Essential amino acids are used to construct
proteins such as enzymes to carry out
metabolism, & body structures – hair, nails,
DNA

Essential refers to the fact that our body can’t
make them so we must eat foods that contain
them

Fat soluble (A,D,E,K) – specialized functions
A synthesis of visual pigments
 D helps regulate calcium 7 phosphorus metabolism
 E is an antioxidant
 K required to form prothrombin (for blood clotting)

Water soluble (C, B complex) – catalysts to
speed up specific reactions
Minerals – macronutrients & micronutrients –
specific functions table 15.5 p 315
