Study Notes
Enzyme Terminology
- The entire active complex of an enzyme, including the apoenzyme and cofactor, is referred to as the holoenzyme.
Enzyme Components
- A cofactor is a non-protein organic substance that is thermostable and loosely attached to the protein part of an enzyme.
Enzyme Function
- The main function of catalysts in enzyme action is to speed up chemical reactions.
Enzymes in Food Production
- Amylase is an enzyme specifically used in bread making to produce dough that will rise easily and hold its shape and cell structure.
- Yeast is used in wine production to produce enzymes such as pectinases, β-glycosidases, and β-glucanases.
Exogenous and Endogenous Enzymes
- Exogenous enzymes are added to a system to perform a specific function.
- The main challenge posed by endogenous enzymes is that they can break down the food itself.
Enzyme Activity
- An active enzyme is differentiated from an inactive enzyme by its ability to catalyze chemical reactions.
Enzyme Classification
- Food enzymes are generally classified as either exogenous or endogenous enzymes.
