Two of these processes, dehydration and hydrolysis, help your body build large Dehydration Synthesis: Definition, Reaction & Examples. Monomers, polymers, dehydration synthesis, and hydrolysis. Proteins themselves have perhaps the broadest range of functions: some provide structural support, but many are This is just a naming difference, so don't get too hung up on it. Reactions of Dehydration Synthesis and Hydrolysis; Roles of Dehydration In relation to what was mentioned above, the water molecule can act as a base . Other examples include the hydrolysis of fat as this helps in the.
Simply put, they are chains of monomers. This makes sense because 'poly' means 'many. There are unique reactions that occur in our bodies to do this.

Dehydration reactions are those that link monomers together to form polymers, and hydrolysis breaks polymers apart into monomers. Dehydration Removes Water When you are thirsty, it's your body's way of telling you to drink some water because you are dehydrated.
Just like a dehydration reaction, you've lost water.
Dehydration reactions are named as such because as the monomers are linked together, a molecule of water is released. This happens because on one end of a monomer is a hydrogen atom -H that is just waiting to bind with a hydroxyl group -OH on another monomer. When they come together, the hydrogen and hydroxyl groups join together like long-lost friends and break free of their monomers.
And what do we get when we have two H atoms and one O atom? H2O, which is water! The bottom line is Hydrolysis occurs when water is added to the equation to break it down or separate it.
In our bodies, Hydrolysis is the main process to release energy. When we eat food, it is digested or broken down into substances so the body can absorb it and convert it to energy.
3.1: Synthesis of Biological Macromolecules
Foods, having complex molecules are broken down into simple molecules. When energy is needed for biosynthesis, ATP is hydrolyzed and stored energy is released for utilization.

Dehydration Synthesis Dehydration means to take away water, and synthesis means to build or create something. Hence, Dehydration Synthesis is defined as taking away water to build something.
This process happens by removing one molecule of —OH hydroxyl group and one molecule of -H to form H2O or water.
Hydrolysis and Dehydration: Definitions & Examples
Examples of hydrolytic reactions are the breaking down of complex sugars, proteins, complex fats, and nucleic acids into monosaccharides, amino acids, fatty acids, and nucleotides. Types of Hydrolysis Various types of hydrolysis occur in living organisms.
The three types are listed below: Salt Hydrolysis This occurs when a salt when a salt is dissolved in water. Acid Hydrolysis According to the Bronsted-Lowry theory, water can act as either an acid or a base.

Base Hydrolysis In relation to what was mentioned above, the water molecule can act as a base and hydrolyze molecules. Reactions of Dehydration Synthesis and Hydrolysis As mentioned earlier, dehydration hydrolysis work the same way in the four major macromolecules. The table below will give you more simplified view of their reactions:
