Explain how condensation forms macromolecules from monomers, and how hydrolysis breaks them back down. Use examples to support your discussion.

  1. Macromolecules are constructed by covalently bonding monomers by condensation reactions where water is removed from functional groups on the monomers. Cellular enzymes carry out condensation (and the reversal of the reaction, hydrolysis of polymers). Condensation involves a dehydration synthesis because a water is removed (dehydration) and a bond is made (synthesis). When two monomers join, a hydroxyl (OH) group is removed from one monomer and a hydrogen (H) is removed from the other. This produces the water given off during a condensation reaction. Hydrolysis (hydration) reactions break down polymers in reverse of condensation; a hydroxyl (OH) group from water attaches to one monomer and hydrogen (H) attaches to the other.

  2. Condensation is when a water is removed through dehydration and when a bond is made through synthesis. Condensation carried by enzymes removes a hydroxyl group from one monomer and a hydrogen group from another monomer so that both monomers can join. These bonded monomers forms macromolecules. Hydrolysis is the reverse of condensation. Instead of dehydrating the hydroxyl group from one monomer and a hydrogen group from another one they attached them to each other.

  4. So, what will usually happen is you'll have one monomer that loses a hydroxyl group, and another that loses a hydrogen:

    monomer---H + HO---monomer ---> monomer---monomer + H2O

    In that reaction, the hydrogen from one monomer reacts with the hydroxyl group of the other to form a water molecule, and the two monomers will be left bonded together. We call that condensation, because the result creates a water molecule. Hydrolysis is the exact opposite reaction, the water molecule comes and splits the bond between two monomers in the reverse of that reaction.

    An example: You get a protein from amino acids when one by one amino acids start forming a long chain using that reaction. Then you can break the protein apart again using hydrolysis.

  5. Macromolecules are formed through condensation; the process in which an H atom is removed from a carbon atom and an OH is removed from another carbon atom. Therefore a water molecule is removed from monomers in order for them to form a macromolecule. In the process of hydrolisis, a macrolecule is broken down into monomers when a water molecule is added to the macromolecule. In other words condensation and hydrolisis are opposite processes of each other.

  6. Macromolecules are made front covalently bonding monomers by condensation reactions where water is taken away from functional groups on the monomers. Cellular enzymes carry out condensation. Condensation involves a dehydration synthesis because a water is removed, called dehydration and a bond is made, called synthesis. When two monomers combine, a hydroxyl group is removed from one monomer and a hydrogen is removed from the other. This produces the water given during a condensation reaction. Hydrolysis, hydration, reactions break down polymers in reverse of condensation. A hydroxyl, the OH, group from water attaches to one monomer and hydrogen attaches to the other.

  7. Condensation is when two molecules are brought together with the loss of water. A monomer may chemically bond with another monomer to form a Polymer. The molecule in which a macromolecule is formed is called a monomer. Two molecules will join to make a macromolecule when a H Atom is removed form a carbon atom and when a OH is removed from another carbon atom. These two atoms will join together to form a macromolecule. Hydrolysis is when water molecules separate into H+ and OH-. This type of reaction is used to break down molecules formed by condensation.

  9. Dehydration synthesis and hydrolysis are the processes used to form and break down macromolecules. Dehydration means to take water out. Theus when you use dehydration synthesis, you are building something up while taking water out. In carbohydrates, an H from one carbohydrate and an OH from another are taken out. They form water. The two carbohydrates are then joine together by a bond called a glycosidic linkage. Hydrolysis is simple the reverse of dehydration synthesis. You add water to a molecule to break it down. If dehydration synthesis continues for a long time, a long and complex carbohydrate chain called a polysaccharide is formed.

  10. Condensation is a chemical process by which 2 molecules are joined together to make a larger, more complex, molecule, with the loss of water. It is the basis for the synthesis of all the important biological macromolecules (carbohydrates, proteins, lipids, nucleic acids) from their simpler sub-units.In all cases of condensation, molecules with projecting -H atoms  are linked to other molecules with projecting  -OH  groups, producing H2O,  ( H.OH ) also known as water, which then moves away from the original molecules.

  11. condensation is made up of two processes, which are dehydration and synthesis. dehydration breaks the compound apart and synthesis forms a new bond. The formation of macro molecules is when a hydrogen group from one monomer and a hydroxyl group from another monomer are taken out to create a bond. hydrolysis is the opposite of condensation. It combines a hydrogen group from one monomer with a hydroxyl group from another monomer without being taken out.
