说明

General description

棕榈酸（C16:0）是一种饱和脂肪酸，常见于各种天然来源，如动物脂肪和植物油。

Application

通过在四氯化碳中与二环己基碳二亚胺（DCC）反应，棕榈酸可用于制备棕榈酸酐。它在300°C和17bar 氩气（5％H₂）压力下，在4％ wt Pd/C介孔催化剂存在下可发生脱氧反应。主要产物为脂肪链长的碳氢化合物，其碳含量比相应的酸少一个碳。

Synthesis of fatty acid anhydrides by reaction with dicyclohexylcarbodiimide.

Z Selinger et al.

Journal of lipid research, 7(1), 174-175 (1966-01-01)

A simple method is described for the preparation of caprylic, palmitic, stearic, and oleic anhydrides. Reaction of the free fatty acid and dicyclohexylcarbodiimide in carbon tetrachloride at room temperature gives the corresponding anhydrides in high yield (87-94%).

Distinct lipid metabolic dysregulation in asymptomatic COVID-19.

Yanhong Hao et al.

iScience, 24(9), 102974-102974 (2021-08-17)

Asymptomatic infection is a big challenge in curbing the spread of COVID-19. However, its identification and pathogenesis elucidation remain issues. Here, by performing comprehensive lipidomic characterization of serum samples from 89 asymptomatic COVID-19 patients and 178 healthy controls, we screened
