A protein that has been partially hydrolyzed (i.e., cleaved) by the peptidase pepsin.
A substance produced by the action of pepsins on proteins in food.
A secondary protein derivative formed during protein digestion in the stomach.
Soluble product of the proteolytic digestion of meat by enzymes such as papain, trypsin etc. Containing polypeptides, amino acids, inorganic salts and growth factors, dissolved peptone is an easily prepared culture medium for the less fastidious bacteria. For more delicate organisms the peptone is incorporated in broths prepared from meat or meat extract.
A large protein fragment produced by the action of enzymes on proteins in the first stages of protein digestion.
A secondary protein formed by the action of proteolytic enzymes, acids, or alkalies on certain proteins.
An intermediary substance in the process of breaking down proteins into amino acids.
