In chemistry, a dehydration reaction is a chemical reaction that involves the loss of water from the reacting molecule or ion. Dehydration reactions are common processes, the reverse of a hydration reaction .
In organic chemistry, a condensation reaction is a type of chemical reaction in which two molecules are combined to form a single molecule, usually with the loss of a small molecule such as water. [1] If water is lost, the reaction is also known as a dehydration synthesis.
Peptide bond formation via dehydration reaction. When two amino acids form a dipeptide through a peptide bond, [1] it is a type of condensation reaction. [2] In this kind of condensation, two amino acids approach each other, with the non-side chain (C1) carboxylic acid moiety of one coming near the non-side chain (N2) amino moiety of the other.
Dehydration synthesis, a chemical synthesis resulting in the loss of a water molecule Biosynthesis , the creation of an organic compound in a living organism, usually aided by enzymes Photosynthesis , a biochemical reaction using a carbon molecule to produce an organic molecule, using sunlight as a catalyst
An aldol condensation is a condensation reaction in organic chemistry in which two carbonyl moieties (of aldehydes or ketones) react to form a β-hydroxyaldehyde or β-hydroxyketone (an aldol reaction), and this is then followed by dehydration to give a conjugated enone. The overall reaction equation is as follows (where the Rs can be H)
In physiology, dehydration is a lack of total body water that disrupts metabolic processes. [3] It occurs when free water loss exceeds free water intake. This is usually due to excessive sweating, disease, or a lack of access to water. Mild dehydration can also be caused by immersion diuresis, which may increase risk of decompression sickness ...
This dehydration reaction produces the desired alkene (3) from an alcohol (1). The reaction is performed in a distillation apparatus so the formed alkene product can be distilled off and collected as the reaction proceeds. The water produced by the reaction as well as some acid will co-distill, giving a distillate mixture (2).
Neutral fats, also known as true fats, are simple lipids that are produced by the dehydration synthesis of one or more fatty acids with an alcohol like glycerol. Neutral fats are also known as triacylglycerols, [1] these lipids are dense as well as hydrophobic due to their long carbon chain and are there main function is to store energy ...
