When you are thirsty, it is your body's way of telling you to drink some water because you are dehydrated. Hydrolysis, which is the reverse of a dehydration reaction, works the same way. What is the difference between dehydration synthesis and hydrolysis?. Water is an important component of cellular processes. Two of these processes, dehydration and hydrolysis, help your body build large.

Open in a separate window Experimental design The effects of the RBC hydration state on parasite invasion and growth were investigated in 2 separate studies using different experimental protocols and various P falciparum strains.

Dehydration/ Hydrolysis Reactions

In the second study study IInormal RBCs and RBCs with different genetic abnormalities were density-fractionated and the different density fractions tested for their ability to sustain P falciparum cultures.

Study I The approach was to assess P falciparum invasion and growth in standard malaria cultures using normal RBCs with altered volumes.

A procedure was required that would enable resetting the RBC volume to any desirable level ensuring its constancy in culture.

Volume changes induced by hypertonic or hypotonic conditions were thus excluded because the high water permeability of RBCs would rapidly re-equilibrate the RBCs in the isotonic culture medium thus reversing the induced volume changes.

Difference Between Hydrolysis and Dehydration Synthesis

It was clear that the volume changes had to be implemented in isotonic conditions. This was done by inducing a reversible permeability change in the RBC plasma membrane allowing a reduction or an increase in the total content of osmotically active solutes within the RBCs. The design of the experimental protocol followed leads from earlier work, as described next.

Fresh RBCs were washed twice by centrifugation and resuspension in over 10 volumes of wash medium W with 0. The buffy coat was removed after each wash. About 5 minutes later, each suspension was transferred into centrifuge tubes containing 9 volumes of ice-cold wash medium W supplemented with 0.

The suspensions were centrifuged at g for 5 minutes, the cells were washed twice more by centrifugation and resuspension in the same medium at a volume-cell ratio of about The use of phenol red-free RPMI was necessary to prevent interference with the measurements of Hb concentrations described.

Synthesis of Biological Macromolecules

RBCs that were not treated with ionophore were used for control cultures. In 2 experiments, the time-dependent shifts in osmotic fragility curves of profoundly dehydrated RBCs were followed over a period of time in parallel with measurements of cell density distribution by separation through phthalate oils, 31 to ascertain whether the observed shifts in the osmotic fragility curves represented rehydration of the cells or loss of membrane area due to microvesiculation.

They are the carboxylic acid and alcohol. For this, a base is used.

Therefore, carboxylate ion is formed instead of carboxylic acid due to its high stability. However, this reaction consumes water molecules in order to provide —OH group for the carboxylic acid formation and the —H group for the alcohol formation. This process is called saponification. Dehydration synthesis is the formation of a larger molecule with the release of water molecules. Hydrolysis is cleavage of a chemical bond in the presence of water. Dehydration synthesis reactions are combination reactions.

Hydrolysis reactions are decomposition reactions.

Dehydration synthesis reaction forms a water molecule. Hydrolysis reaction consumes a water molecule. The reactants of dehydration synthesis reactions are smaller molecules than their products.

Synthesis of Biological Macromolecules

The reactants of hydrolysis reactions are complex molecules than their products. Dehydration synthesis reactions give water molecules as byproducts.

Hydrolysis reactions do not give byproducts. Conclusion Both dehydration synthesis and hydrolysis are chemical reactions that are occurred in the presence of water. That is because dehydration synthesis reactions provide water molecules to the medium whereas hydrolysis reactions consume water molecules from the reaction mixture.

The main difference between dehydration synthesis and hydrolysis is that dehydration synthesis results in the formation of a large molecule out of smaller molecules whereas hydrolysis results in smaller molecules out of a large molecule.
