protein and amino acids part 2

stomach acids

denture protein and activate pepsin

small intestine

polypeptides are broken down into tripeptides, dipeptides and amino acids

amino acids enter the blood and then

travel to the liver

amino acids are used to make 

body proteins & non-protein substances 

after amino groups are removed they can be

burned for energy, stored as fat and made into glucose

protein quality is determined by 2 factors 

the protein’s digestibility, and the protein's amino acid profile 

amino acid profile

the types and amounts of amino acids that the protein contains

complete proteins

all essential amino acids plus some nonessential amino acids

incomplete proteins 

low in one or more essential amino acids 

deamination

The removal of an amino group from an amino acid or other compound.

transamination

amino groups are removed from amino acids
