Breakdown of proteins produce aminoacids.
These are several aminoacids.
Amino acids, but they can also be broken down further thru metabolism.
Stomach - highly acidic environment will denature and/or break down proteins.
Amylase helps speed up breakdown of starch molecules.
Proteases are enzymes that speed up the breakdown of proteins.
It is the chemical hydrogen sulfide (H2S), which is produced by the breakdown of proteins containing the amino acid cysteine.
Proteases break down proteins.
The enzyme that speeds up the breakdown of proteins in food are called protease.
Mechanical breakdown helps chemical breakdown because when you chew, chemical breakdown is going on all at the same time. So, that is going to chemical because if you didn't have saliva (chemical breakdown) if would take real long to digest your food.
The breakdown of proteins is a problem for animals for quite a few reasons. Proteins are complex and some animals don't have the ability to break them down.
Mechanical breakdown makes food smaller so it wasn't be so large for the chemical breakdown.
