What is the function of aldehyde dehydrogenase?
Aldehyde dehydrogenase (ALDH) is a superfamily of enzymes that detoxify a variety of endogenous and exogenous aldehydes and are required for the biosynthesis of retinoic acid (RA) and other molecular regulators of cellular function.
Where is aldehyde dehydrogenase produced?
ALDH2, an aldehyde dehydrogenase found in the mitochondrial matrix, is expressed in many organs, such as liver, kidney, heart, lungs, and brain. ALDH2 is most abundantly expressed in the liver. It is also highly expressed in heart and brain, which require highly oxidative phosphorylation of mitochondria.
What happens if aldehyde dehydrogenase is inhibited?
Inhibition of these isozymes leads to the accumulation of neurotoxic dopamine metabolites, such as 3,4-dihydroxyphenylacetaldehyde, that are thought to contribute to the pathogenesis of Parkinson’s disease (Burke et al., 2003; Marchitti et al., 2007; Allen et al., 2010).
What causes aldehyde?
Aldehydes are organic compounds that are widespread in nature. They can be formed endoge- nously by lipid peroxidation (LPO), carbohydrate or metabolism ascorbate autoxidation, amine oxidases, cytochrome P-450s, or myeloperoxidase-catalyzed metabolic activation.
What is the smell of aldehydes?
Aldehydes and ketones are known for their sweet and sometimes pungent odors. The odor from vanilla extract comes from the molecule vanillin. Likewise, benzaldehyde provides a strong scent of almonds and is this author’s favorite chemical smell.
Is aldehyde toxic to humans?
Aldehydes are carbonyl compounds found ubiquitously in the environment, derived from both natural and anthropogenic sources. As the aldehydes are reactive species, therefore, they are generally toxic to the body.
What foods contain aldehyde?
6.26. 2 Sources and Levels of Environmentally Important Aldehydes
| Aldehyde(s) | Concentration | |
|---|---|---|
| Codfish fillets (Lane and Smathers 1991) | Acrolein | 100 μg kg−1 |
| Cheese (Collin et al. 1993) | Acrolein | 290–1300 μg kg−1 |
| Red wine (Miller and Danielson 1988) | Acrolein | 3800 μg kg−1 |
| Vinegar (Feron et al. 1991) | Acetaldehyde | 1.06 gm kg−1 |
Do aldehydes have a smell?
Aldehydes and ketones are known for their sweet and sometimes pungent odors. Likewise, benzaldehyde provides a strong scent of almonds and is this author’s favorite chemical smell. Because of their pleasant fragrances aldehyde and ketone containing molecules are often found in perfumes.
