Difference Between Substrate and Product

Key Difference – SubstratevsProduct

Thekey differencebetween substrate and product is thatsubstrate is the staring material of a chemical reaction whereas product is the compound obtained after the completion of the reaction.

The terms substrate and product are used in spontaneous reactions and in reactions upon which an enzyme acts on as a catalyst. The substrate is the compound on which the enzyme acts on. The product is the compound that is obtained when the reaction has completed.

What is a Substrate?

底物的起始物料的化学reaction. Substrate is the compound that is being modified or undergo rearrangement during a chemical reaction. For biochemical reactions, the substrate is the compound on which an enzyme acts. The concentration of substrate changes with time of the progression of a chemical reaction; the substrate concentration decreases. There can be one or more substrates involved in a reaction.

When considering biochemical reactions, the substrate binds to the enzyme. The substrate gets attached to the locations of the enzyme known as active sites. Then, a substrate-enzyme complex forms. The reaction takes place on the enzyme. The products of the reaction are released from the active site later.

什么是产品?

产物是化学反应结束时获得的化合物。产品是反应的结果。可以从化学反应中获得一个或多个产品。反应的起始材料称为反应物或底物。在化学反应过程中可能会发生重排，粘结形成或键断裂，以提供产物。

在编写反应方程时，箭头用于显示反应的方向。在那里，当反应物在左侧时，产品显示在右侧（箭头指向的箭头指向）。例如：A和B之间的反应给出C和D作为产品。然后写如下。

A + B → C + D

The products given from a particular chemical reaction can be either major products or minor products. The major product is the product that is given at a higher percentage than other products. Minor products are also known as byproducts. Sometimes, the chemical composition of the reactant and product is similar, only the phase of matter is different.

What is the Difference Between Substrate and Product?

底物与产品
基质is the starting material for a chemical reaction.	产物是化学反应结束时获得的化合物。
Position in a Chemical Equation
基质s are given on the right-hand side of the chemical equation.	Products are given on the left-hand side of the chemical equation.
Beginning of the Reaction
The chemical reaction begins with a high concentration of substrate.	There are no products at the beginning of the chemical reaction.
Progression of the Reaction
The substrate concentration decreases with the progression of the reaction.	The product concentration increases with the progression of reaction.
End of the Reaction
There are no or less number of substrates at the end of the reaction.	There is a high number of products at the end of the reaction.

概括– SubstratevsProduct

基质s and products are found in reaction mixtures. Substrates are the starting material of the reaction whereas products can be obtained at the end of the reaction. The difference between substrate and product is that the substrate is the starting material of a chemical reaction whereas product is the compound obtained after the completion of the reaction.
