Description

Technical Field

[0001] The utility model relates to the technical field of enzymolysis, in particular to a multi-stage enzymolysis reaction device. Background Art

[0002] Most enzymes are proteins and act as biocatalysts. Specific enzymes can catalyze specific chemical reactions, accelerating them and reducing the activation of reactants. They are often used in the preparation of small-molecule peptides due to their high catalytic efficiency, strong specificity, and mild reaction conditions, without excessive contamination that could interfere with the reaction.

[0003] Enzymatic hydrolysis, also known as enzymolysis, is a biochemical process that uses specific enzymes to break down organic matter into smaller organic or inorganic compounds. It refers to the process where a biocatalyst catalyzes the breakdown of specific organic matter into new organic matter.

[0004] Enzymes accelerate or promote chemical reactions by reducing or increasing the activity of reactants. In enzymatic reactions, enzymes do not directly participate in the reaction, but provide a catalytic environment that makes it easier for reactants to be converted into products.
