General description
丙酸（PA）是一种天然羧酸，它在纯态下是一种无色的腐蚀性液体，具有难闻的气味。它可与水混溶。工业上以羰基镍作为催化剂，通过乙烯的加氢羧化作用制备丙酸。已有研究发现PA可减少食物摄入量、降低血浆和肝脏的脂肪酸含量、改善组织胰岛素敏感性并发挥免疫抑制作用。丙酸是一种出色的原材料，因为它稳定、廉价且安全，甚至可以用作食品添加剂。

Undigested food is fermented in the colon by the microbiota and gives rise to various microbial metabolites. Short-chain fatty acids (SCFA), including acetic, propionic and butyric acid, are the principal metabolites produced. However, most of the literature focuses on butyrate

Metabolites released by the gut microbiota may influence host metabolism and immunity. We have tested the hypothesis that inulin-type fructans (ITF), by promoting microbial production of short-chain fatty acids (SCFA), influence cancer cell proliferation outside the gut. Mice transplanted with
