一般描述

乙酸是一种有机羧酸。这是一种有刺激性气味的易吸潮的液体。冰醋酸是无水乙酸。它通过溶液中的氢键和通常称为相的气体形成二聚体。它呈弱酸性。

应用

乙酸被广泛地用作各种氧化反应的溶剂。它可用于电子转移(ETD)离解串联质谱(MS/MS)分析合成多肽。它可与过氧化氢(30%过氧化氢)反应制备过氧乙酸(消毒剂)。

Autonomic sympathetic nerves innervate peripheral resistance arteries, thereby regulating vascular tone and controlling blood supply to organs. Despite the fundamental importance of blood flow control, how sympathetic arterial innervation develops remains largely unknown. Here, we identified the axon guidance cue
