Lipase

1. product overview

Lipase is a special kind of ester key enzymes and bioactive catalyst. In the aqueous phase or organic phase lipase catalytic hydrolysis, alcohol solution can be, esterification, a variety of types such as the ester exchange reaction. These reactions are reversible reaction, need to control conditions urges towards direction needed Reaction.

2. Product properties and reaction conditions

Pale yellow powder. The optimum temperature for 40 ℃, the optimal pH 8.0-8.5.

3.Product characteristics

An important characteristic of lipase is that it only in the water system, which out-of-phase not soluble grease - on ShuiJie function, to well-proportioned dispersing and water-soluble substrates without effect very slowly or function.

The lipase catalytic esterification, and turn the esterification and ester exchange reaction best reaction temperature of 40 ℃, reaction system in general will contain trace amounts of water, after mixing or shock, the reaction medium and enzymes in the fully contact with the same time, more important is in organic phase formation water environment for lipase micro, provide for water-oil interfacial effect。Sometimes have added to the reaction system response to start small amounts of water. Reaction, some of enzyme adverse effects of substrate, such as partial join to short chains such as alcohol, glycerin strong polarity substance; Reaction process should be timely remove reaction products, because the reaction product accumulates suppresses reaction, some products will also produce poisonous effect of enzyme; A substrate can improve the appropriate overdose, another kind of substrates conversion.

4. Application methods

The substrate to hydrolysis in commonly water solubility is small, in order to make the substrates and enzyme full contact, need to add some suitable emulsifier, mixing and shock to form a stable water-oil interfacial, make reaction sufficiently. When used according to need to say take right amount, role avoid enzyme with cationic surfactants on the enzyme beneath live action Shared material.

Enzyme catalysis suffer reaction conditions, balance control, enzyme action environment etc, when using multiple factors according to actual situation comprehensive consideration of the optimum reaction conditions and reaction dosage.
