2-Oxo-4-methylthiobutanoic acid
2-oxo-4-methylthiobutanoate, also known as 2-keto-4-methylthiobutyric acid, 2-keto-4-methylthiobutyrate or 4-(methylsulfanyl)-2-oxobutanoic acid, is a member of the class of compounds known as thia- fatty acids. Thia-fatty acids are fatty acid derivatives obtained by insertion of a sulfur atom at specific positions in the chain. Thus, 2-oxo-4-methylthiobutanoate is a fatty acid lipid molecule. 2-oxo-4-methylthiobutanoate is slightly soluble (in water) and a weakly acidic compound (based on its pKa). 2-oxo-4-methylthiobutanoate can be synthesized from L-methionine and butyric acid. 2-oxo-4-methylthiobutanoate can also be synthesized into S-adenosyl-4-methylthio-2-oxobutanoic acid. 2-oxo-4-methylthiobutanoate can be found in a number of food items such as cloves, highbush blueberries, common beets, and cashew nuts. 2-oxo-4-methylthiobutanoate can be found in urine. Within the cell, 2-oxo-4-methylthiobutanoate is primarily located in the cytoplasm and in the membrane. 2-oxo-4-methylthiobutanoate has been found in all living species, from bacteria to humans. In humans, 2-oxo-4-methylthiobutanoate is found to be involved in several metabolic disorders, some of those are S-adenosylhomocysteine (SAH) hydrolase deficiency, methylenetetrahydrofolate reductase deficiency (MTHFRD), methionine adenosyltransferase deficiency, and glycine N-methyltransferase deficiency. 4-Methylthio-2-oxobutanoic acid is the direct precursor of methional, which is a potent inducer of apoptosis in a BAF3 murine lymphoid cell line which is interleukin-3 (IL3)-dependent (PMID: 7848263). 2-oxo-4-methylthiobutanoic acid, also known as 2-keto-4-methylthiobutyrate or 4-methylthio-2-oxobutanoate, is a member of the class of compounds known as thia fatty acids. Thia fatty acids are fatty acid derivatives obtained by insertion of a sulfur atom at specific positions in the chain. Thus, 2-oxo-4-methylthiobutanoic acid is considered to be a fatty acid lipid molecule. 2-oxo-4-methylthiobutanoic acid is slightly soluble (in water) and a weakly acidic compound (based on its pKa). 2-oxo-4-methylthiobutanoic acid can be synthesized from L-methionine and butyric acid. 2-oxo-4-methylthiobutanoic acid can also be synthesized into S-adenosyl-4-methylthio-2-oxobutanoic acid. 2-oxo-4-methylthiobutanoic acid can be found in a number of food items such as leek, hickory nut, brussel sprouts, and giant butterbur, which makes 2-oxo-4-methylthiobutanoic acid a potential biomarker for the consumption of these food products. 2-oxo-4-methylthiobutanoic acid can be found primarily in urine. 2-oxo-4-methylthiobutanoic acid exists in all living species, ranging from bacteria to humans. In humans, 2-oxo-4-methylthiobutanoic acid is involved in the methionine metabolism. 2-oxo-4-methylthiobutanoic acid is also involved in several metabolic disorders, some of which include s-adenosylhomocysteine (SAH) hydrolase deficiency, homocystinuria-megaloblastic anemia due to defect in cobalamin metabolism, cblg complementation type, glycine n-methyltransferase deficiency, and cystathionine beta-synthase deficiency.
Phthalic anhydride
Phthalic anhydride is the organic compound with the formula C6H4(CO)2O. It is the anhydride of phthalic acid. Phthalic anhydride is a principal commercial form of phthalic acid. It was the first anhydride of a dicarboxylic acid to be used commercially. This white solid is an important industrial chemical, especially for the large-scale production of plasticizers for plastics. In 2000, the worldwide production volume was estimated to be about 3 million tonnes per year.
