understand the synthetic of macromolecules define dehydration (or condensation) and hydrolysis reactions

As you’ve learned, barisalcity.orglogical macromolecules are huge molecules, crucial for life, that are constructed from smaller organic molecules. There are four major classes of barisalcity.orglogical macromolecules (carbohydrates, lipids, proteins, and also nucleic acids); each is an important cell component and also performs a vast array of functions. Combined, these molecules make up the majority of a cell’s dry mass (recall that water provides up the bulk of its finish mass). Organic macromolecules room organic, meaning they save carbon. In addition, they might contain hydrogen, oxygen, nitrogen, and extr minor elements.

Dehydration Synthesis

Most macromolecules room made from single subunits, or structure blocks, called monomers. The monomers combine with each other using covalent bond to form larger molecules known as polymers. In law so, monomers release water molecules as byproducts. This type of reaction is recognized as dehydration synthesis, which way “to put together while shedding water.”

Figure (PageIndex1): In the dehydration synthesis reaction depicted above, 2 molecules the glucose are attached together to kind the disaccharide maltose. In the process, a water molecule is formed.

In a dehydration synthesis reaction (Figure (PageIndex1)), the hydrogen the one monomer combines through the hydroxyl group of one more monomer, publication a molecule the water. At the exact same time, the monomers share electrons and form covalent bonds. As extr monomers join, this chain that repeating monomers creates a polymer. Different species of monomers can combine in numerous configurations, offering rise to a varied group the macromolecules. Even one type of monomer can integrate in a range of means to type several different polymers: because that example, glucose monomers are the constituents of starch, glycogen, and also cellulose.


Polymers are broken down right into monomers in a process known together hydrolysis, which way “to split water,” a reaction in i m sorry a water molecule is used during the breakdown (Figure (PageIndex2)). Throughout these reactions, the polymer is broken into 2 components: one component gains a hydrogen atom (H+) and the various other gains a hydroxyl molecule (OH–) from a break-up water molecule.
