一般描述

棕榈酸（PA）是一种存在于人体内的饱和脂肪酸，占膜磷脂（PL）和脂肪三酰甘油（TAG）中总脂肪酸（FA）的20-30%。它是棕榈油的主要成分之一，在肉类和乳制品、可可脂和橄榄油中也发现了大量的PA。母乳中也含有PA。PA在细胞和组织水平上执行各种基本的生物学功能。

应用

棕榈酸已用于：
  • 研究对单核细胞趋化蛋白-1（MCP-1）在脂肪细胞和THP-1巨噬细胞中表达的影响
  • 刺激原代大鼠肝细胞脂毒性
  • 在牛血清白蛋白（BSA）溶液中加入维甲酸（RA）和视黄醇，研究对精子发生和减数分裂进程的影响

Although short-term incubation of hepatocytes with oleic acid (OA) stimulates secretion of apolipoprotein B100 (apoB100), exposure to higher doses of OA for longer periods inhibits secretion in association with induction of endoplasmic reticulum (ER) stress. Palmitic acid (PA) induces ER

Saturated fatty acids (SFAs) induce hepatocyte cell death, wherein oxidative stress is mechanistically involved. Nuclear factor (erythroid-derived 2)-like 2 (Nrf2) is a master transcriptional regulator of cellular antioxidant defense enzymes. Therefore, Nrf2 activation is regarded as an effective strategy against

High levels of free fatty acids (FFA) have been suggested to be one of the underlying mechanisms for adipose tissue (AT) inflammation and dysfunction in obesity. Human AT produces several adipokines including monocyte chemoattractant protein-1 (MCP-1), which are involved in

Lipotoxicity induced by saturated fatty acids (SFAs) plays a pathological role in the development of non-alcoholic fatty liver disease (NAFLD); however, the exact mechanism(s) remain to be clearly elucidated. Toll-like receptor (TLR) 4 plays a fundamental role in activating the

Recent data indicate that peripheral insulin sensitivity may be influenced by dietary fat quality and skeletal muscle phospholipid fatty acid composition. During a health survey of 70-year-old men insulin sensitivity was measured by the euglycaemic hyperinsulinaemic clamp technique and the
