Product details:
Aldehyde Assay Kit II (Colorimetric - Blue) (ab219923) provides a sensitive mix-and-read method to detect aldehyde in a variety of samples such as cell lysates or biological fluids. This assay used a proprietary sensor that upon reacting with an aldehyde, generates a chromogenic product that can be detected by absorbance on a microplate reader at OD620-660 nm. This assay can detect as little as 3 μM aldehyde (0.3 nmol/100 μL assay volume).
The assay can be performed in a convenient 96-well or 384-well plate format and is easily adapted to automation without a separation step.
If your plate reader does not have the appropriate filter to detect the absorbance change, we recommend Aldehyde Quantification Assay Kit (Colorimetric) (
ab112113
), which can be read at OD405 or OD550 nm.
Very reactive aldehydes, namely 4-hydroxyalkenals, were first shown to be formed in autoxidizing chemical systems. It was subsequently shown that 4-hydroxyalkenals, particularly 4-hydroxynonenal, were formed in substantial amounts under biological conditions, i.e. during the peroxidation of lipids of liver microsomes incubated in the NADPH-Fe system. Many other aldehydes were also identified in peroxidizing liver microsomes orhepatocytes, e.g., alkanals, alk-2-enals, and 4-hydroxyalkenals.
Rapid and accurate measurement of aldehydes is an important task for biological and chemical research, as well as food industry and environmental pollution surveillance.

Aldehydes play an important role in various biological processes. Also known as aliphatic aldehydes or aromatic aldehydes when describing specific types aldehydes can be seen throughout different environments in the human body. These small organic compounds possess a molecular mass that varies depending on the specific type of aldehyde but they generally consist of a carbonyl center with a hydrogen atom single-bonded to the carbon atom making them relatively lightweight molecules. Aldehydes are highly reactive and widely distributed in several tissues and organs such as the liver where they are heavily expressed due to the organ's metabolic functions.
Biological function summary
Aldehydes do several critical tasks in the body. They are involved in metabolic processes such as energy production and detoxification. Aldehydes can also act as signaling molecules to influence various pathways. Aldehyde dehydrogenase enzymes often act in conjunction with aldehydes transforming them into less reactive carboxylic acids. This metabolic action highlights their role as part of larger multistep enzymatic pathways demonstrating their involvement in cellular metabolism and chemical detoxification processes.
Pathways
Aldehydes participate in critical metabolic pathways including gluconeogenesis and ethanol metabolism. In the ethanol metabolism pathway the enzyme alcohol dehydrogenase initially converts ethanol into acetaldehyde which aldehyde dehydrogenase then oxidizes to acetic acid. This pathway plays a role in both energy production and cellular detoxification. Aldehydes also interact with proteins such as cytochrome P450 enzymes which are key components of drug metabolism pathways assisting in the processing of endogenous and exogenous compounds.
Aldehydes have been associated with conditions like alcohol-related liver disease and Alzheimer's disease. Acetaldehyde a type of aldehyde is implicated in the toxicity of alcohol consumption leading to liver damage when accumulated excessively. Elevated levels of aldehydes have also been detected in neurodegenerative conditions; they can contribute to oxidative stress and neuronal damage. Proteins such as amyloid-beta in Alzheimer's disease are influenced by aldehydes which can exacerbate pathological states. Understanding aldehyde function provides insight into both normal physiology and these disease mechanisms.
