Common Name3-Methyl butanoic acid
DescriptionIsovaleric acid, also known as 3-methylbutanoic acid or beta-methylbutyric acid, belongs to the class of organic compounds known as methyl-branched fatty acids. These are fatty acids with an acyl chain that has a methyl branch. Usually, they are saturated and contain only one or more methyl group. However, branches other than methyl may be present. Isovaleric acid is also classified as a fatty acid. It exists as a colorless liquid that is sparingly soluble in water. Isovaleric acid exists in all living species, ranging from bacteria to plants to humans. It is frequently found in a wide variety of plants and essential oils. Isovaleric acid has a strong pungent cheesy or sweaty smell. It is a major component of strong foot odor as it is produced by skin bacteria metabolizing leucine (PMID: 16699586 ). An excess of isovaleric acid in wine is generally seen as a defect, as it can give wines a sweaty, leathery, or barnyard-like smell. In wine, isovaleric acid is produced by the spoilage yeast Brettanomyces. In small amounts isovaleric acid can smell smokey, spicy, or medicinal. Isovaleric acid is found in many different plants and foods such as apples, bananas, roasted barley, beer, blackberry fruit, brandy, cheese, sour cherry, cinnamon, cider, citrus fruits, cocoa, coffee, cornmint plants, fish, grapes, hops, milk, mushrooms, papaya, passion fruit, peaches, pears, peanuts, peas, celery, safflower, yellow bell peppers, black pepper, raspberries, rosemary, strawberry, spearmint, tea, tomatoes and valerian root. It has been proposed that isovaleric acid is the anticonvulsant agent in valerian (PMID: 15509234 ). Isovaleric acid has been shown to be a a protein kinase A (PKA) agonist and causes smooth muscle relaxation via the PKA pathway (PMID: 30560338 ). Isovaleric acid (along with isovalerylcarnitine) is eleveated in the serum of patients with isovaleric acidemia. Isovaleric acidemia (IVA) is a rare autosomal recessive disorder of leucine metabolism caused by a defective isovaleryl-CoA dehydrogenase (IVD) gene (PMID: 32505769). Health problems related to isovaleric acidemia range from very mild to life-threatening. In severe cases, the features of isovaleric acidemia become apparent within a few days after birth. The initial symptoms include poor feeding, vomiting, seizures, and lack of energy (lethargy). These symptoms sometimes progress to more serious medical problems, including seizures, coma, and possibly death. A characteristic sign of isovaleric acidemia is a distinctive odor of sweaty feet during acute illness. Isovaleric acid is one of several acidic compounds found in cannabis smoke and is formed during the combustion of cannabis ( Ref:DOI ).

Enzymes

General function:
Involved in transferase activity, transferring hexosyl groups
Specific function:
UDPGT is of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds. This isoform glucuronidates bilirubin IX-alpha to form both the IX-alpha-C8 and IX-alpha-C12 monoconjugates and diconjugate. Is also able to catalyze the glucuronidation of 17beta-estradiol, 17alpha-ethinylestradiol, 1-hydroxypyrene, 4-methylumbelliferone, 1-naphthol, paranitrophenol, scopoletin, and umbelliferone.
