Examples of monosaccharides are glucose (in energy drinks) and fructose (in fruits). The reaction takes place within two functional groups in the molecules. Lack of the water in living organisms is called dehydration. Water is essential for most life processes, including photosynthesis, cellular respiration, and other chemical reactions that occur in organisms. Do you expect the dehydration of 1-methylcyclohexanol to proceed by an E1 or E2 mechanism? In biology and chemistry, a dehydration synthesis reaction (or a condensation reaction) is one that synthesizes —or joins—two molecules together, resulting in a loss of water.It may not sound like much, but the underlying importance of dehydration synthesis is that it is central to the production of larger biological molecules to be used in other biological processes. Anyone can earn There's another kind of dehydration reaction you'll see in inorganic chemistry. We will use two different dehydration synthesis examples to illustrate what happens in the presence, or absence, of an acid catalyst. Visit the AP Biology: Tutoring Solution page to learn more. Visit the High School Biology: Help and Review page to learn more. Put them together, and the definition matches our experience: 'removal of water' means dehydration. Monosaccharides, disaccharides, and polysaccharides. There's another kind of dehydration reaction you'll see in inorganic chemistry.
