Tiglic acid

alpha,beta-dimethyl acrylic acid; 2-Methyl-2-butenoic acid; (E)-2-methyl-Crotonic acid

C5H8O2 (100.05242679999999)


Tiglic acid is a monocarboxylic unsaturated organic acid. It is found in croton oil and in several other natural products. It has also been isolated from the defensive secretion of certain beetles. Tiglic acid, also known as tiglate or tiglinsaeure, 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. Tiglic acid has a double bond between the second and third carbons of the chain. Tiglic acid and angelic acid form a pair of cis-trans isomers. Tiglic acid is a volatile and crystallizable substance with a sweet, warm, spicy odour. It is used in making perfumes and flavoring agents. The salts and esters of tiglic acid are called tiglates. Tiglic acid is a 2-methylbut-2-enoic acid having its double bond in trans-configuration. It has a role as a plant metabolite. It is functionally related to a crotonic acid. Tiglic acid is a natural product found in Aloe africana, Azadirachta indica, and other organisms with data available. See also: Arctium lappa Root (part of); Petasites hybridus root (part of).

C4H8O2 (88.0524268)


Isobutyric acid is a carboxylic or short chain fatty acid with characteristic sweat-like smell. Small amount of isobutyrate is generated via microbial (gut) metabolism. Small amounts may also be found in certain foods or fermented beverages. There is anosmia (genetic inability to smell) for the odor of isobutyric acid with a frequency of about 2.5\\%. (OMIM 207000). Isobutyric acid is slightly soluble in water but much more soluble in ethanol, ether and organic solvents. Isobutyric acid can affect people if breathed in and may be absorbed through the skin. Contact can irritate and burn the skin and eyes. Breathing Isobutyric acid can irritate the nose, throat and lungs causing coughing, wheezing and/or shortness of breath. Present in apple, morello cherry, guava fruit, wine grapes, pineapple, crispbread, other breads, cheeses, wines, scallop and several essential oils, e.g. Roman chamomile.

Isovaleric acid, is a natural fatty acid found in a wide variety of plants and essential oils. Isovaleric acid is clear colorless liquid that is sparingly soluble in water, but well soluble in most common organic solvents. It has been suggested that isovaleric acid from pilot whales, a species frequently consumed in the Faroe Islands, may be the unusual dietary factor in prolonged gestation in the population of the Faroe Islands. Previous studies suggested that was due to the high intake of n-3 polyunsaturated fatty acids has been, but fatty acid data for eicosapentaenoic acid (EPA) and docosahexanoic acid (DHA) in blood lipids of Faroese and Norwegians was reviewed in terms of the type of fish eaten (mostly lean white fish with DHA much greater than EPA); the popular lean fish, thus, probably provides too little EPA to produce a marked effect on human biochemistry (PMID 2646392). Isovaleric acid is found to be associated with isovaleric acidemia, which is an inborn error of metabolism. Flavouring agent. Simple esters are used in flavourings.

Valproic acid

Valproic acid, sodium salt (2:1)

C8H16O2 (144.1150236)


Valproic acid (VPA) is considered to be a drug of first choice and one of the most frequently-prescribed antiepileptic drugs worldwide for the therapy of generalized and focal epilepsies, including special epileptic. It is a broad-spectrum antiepileptic drug and is usually well tolerated. Rarely, serious complications may occur in some patients, including hemorrhagic pancreatitis, coagulopathies, bone marrow suppression, VPA-induced hepatotoxicity and encephalopathy, but there is still a lack of knowledge about the incidence and occurrence of these special side effects. VPA has been approved for stabilization of manic episodes in patients with bipolar disorder. It is also used to treat migraine headaches and schizophrenia. As the use of VPA increases, the number of both accidental and intentional exposures increases. This is paralleled by more reports of VPA-induced toxicity. VPA is relatively contraindicated in pregnancy due to its teratogenicity. It is a known folate antagonist, which can cause neural tube defects. Thus, folic acid supplements may alleviate teratogenic problems. Women who become pregnant whilst taking valproate should be counselled as to its risks. VPA is an inhibitor of the enzyme histone deacetylase 1 (HDAC1). HDAC1 is needed for HIV to remain in infected cells. Patients treated with valproic acid in addition to highly active antiretroviral therapy (HAART) showed a median 75\\% reduction in latent HIV infection. VPA is believed to affect the function of the neurotransmitter GABA (as a GABA transaminase inhibitor) in the human brain. Valproic Acid dissociates to the valproate ion in the gastrointestinal tract.
