一般描述

丁酸是一种含有四个碳的饱和短链脂肪酸。它通常以酯的形式存在于动物脂肪和植物油中。它是一种有效的细胞分化剂,也具有抗增殖活性。在培养的哺乳动物细胞中,它会影响生长速度、形态和基因表达。它还诱导细胞凋亡。
这种物质被列入EU第10/2011号法规中用于与食品接触的塑料的正面清单。10/2011号清单所列全部化合物的标准物质见此

We describe a procedure for preparing fecal samples for determination of volatile fatty acids (VFAs) by gas-liquid chromatography (GLC) and "high-performance" liquid chromatography (HPLC). The simple, one-step procedure involves only ultrafiltration through a membrane with a molecular-mass cutoff of 3000

Multifunctional acyloxyalkyl ester prodrugs of 5-aminolevulinic acid in cancer cell lines inhibited the proteasome and induced apoptosis and heme synthesis. The most potent prodrug was butyryloxymethyl 5-amino-4-oxopentanoate (1a). The metabolically released formaldehyde from the prodrugs was the dominant factor affecting
