How does hydrolysis compared to dehydration synthesis

Each macromolecule is broken down by a specific enzyme. For instance, carbohydrates are broken down by amylase, sucrase, lactase, or maltase. Proteins are broken down by the enzymes trypsin, pepsin, peptidase and others. Lipids are broken down by lipases. Once the smaller metabolites that result from these hydrolytic enzymezes are absorbed by cells in the body, they are further broken down by other enzymes.

The breakdown of these macromolecules is an overall energy-releasing process and provides energy for cellular activities. Learning Objectives Explain hydrolysis reactions. Key Points Hydrolysis reactions use water to breakdown polymers into monomers and is the opposite of dehydration synthesis, which forms water when synthesizing a polymer from monomers.

Hydrolysis reactions break bonds and release energy. Biological macromolecules are ingested and hydrolyzed in the digestive tract to form smaller molecules that can be absorbed by cells and then further broken down to release energy. Key Terms enzyme : a globular protein that catalyses a biological chemical reaction hydrolysis : A chemical process of decomposition involving the splitting of a bond by the addition of water. Each protein or nucleic acid with a different sequence is a different molecule with different properties.

Hydrolysis reactions result in the breakdown of polymers into monomers by using a water molecule and an enzymatic catalyst.

During these reactions, the polymer is broken into two components. If the components are un-ionized, one part gains a hydrogen atom H- and the other gains a hydroxyl group OH— from a split water molecule. This is what happens when monosaccharides are released from complex carbohydrates via hydrolysis. Hydrolysis reaction generating un-ionized products.

One glucose gets a hydroxyl group at the site of the former covalent bond, the other glucose gets a hydrogen atom. This is the reverse of the dehydration synthesis reaction joining these two monomers.

If the components are ionized after the split, one part gains two hydrogen atoms and a positive charge, the other part gains an oxygen atom and a negative charge. This is what happens when amino acids are released from protein chains via hydrolysis.

Hydrolysis reaction generating ionized products. One amino acid gets an oxygen atom and a negative charge, the other amino acid gets two hydrogen atoms and a positive charge. These reactions are in contrast to dehydration synthesis also known as condensation reactions.

In dehydration synthesis reactions, a water molecule is formed as a result of generating a covalent bond between two monomeric components in a larger polymer. In hydrolysis reactions, a water molecule is consumed as a result of breaking the covalent bond holding together two components of a polymer.

In our bodies, food is first hydrolyzed, or broken down, into smaller molecules by catalytic enzymes in the digestive tract.

This allows for easy absorption of nutrients by cells in the intestine. Each macromolecule is broken down by a specific enzyme.

Dehydration Synthesis Dehydration means to take away water, and synthesis means to build or create something.
