Hydrolysis.

By: Kevin and Htet


Hydrolysis is classified as a chemical reaction which occurs between hydrogen (H+) and hydroxide (OH) ions with water molecules. This happens when the molecule is “cleaved” into two parts, with one particle gaining a hydrogen ion from the water molecule whilst the other collects the remaining hydroxyl group (connected by a covalent/single bond). In other words, it can be described as the process of a large molecule or compound being split with the addition of  water.


Generally, the most common form of Hydrolysis occurs when salt is dissolved into water, causing their ions to form an acid and a base (one of which has slight dissociation). Different results of Hydrolysis can be achieved under different conditions, i.e. under normal conditions, hydrolysis is considered less effective as fewer reactions occur. In today’s world, there are several uses of Hydrolysis, including utilization in natural energy resources, meat processing, and as a reaction in the breaking down energy sources. 


Hydrolysis Uses:

Natural energy:                                                                                                                         

Hydrolysis cell can be used in the generation of wind power through a process of converting  kinetic energy into chemical energy (provided an electrical current and magnetic field environment. This conversion of energy can level the fluctuations in kinetic energy within windmill power systems, thus rendering the mills to act more efficiently.

Meat Processing:  

Thermal Hydrolysis can be used during the process of certain organic animal by-products. When the temperature is set at 180 degrees C and excessive pressure is added, complex proteins can be broken down into simple amino acids and peptides. These products can destroy all pathogens (germs) present in meat resources such as cattle, sheep,  elk, and deer.


Breaking Down Starch:


A common use of Hydrolysis is during the process of the breaking down of starch, where it is considered the key reaction. Starch can be broken down two ways, both including hydrolysis reactions:

1. Starch is boiled with diluted hydrochloric acid and broken down into glucose molecules.

2. Starch is mixed with saliva for a few minutes and is broken down into maltose.

The first reaction utilizes acid hydrolysis whilst the second uses enzyme hydrolysis. Thus, the result depends on which type of hydrolysis is used.


In conclusion, it could be said that Hydrolysis is a very useful chemical reaction in the modern world. With the innovative use of Hydrolysis to sterilize food, aid in wind power generation, and breaking down of food sources, Hydrolysis has helped us in more ways than we could imagine.  Who knew that by just dissolving salt into water, scientists could achieve such results!
