4-甲基伞形基棕榈酸酯

4-甲基伞形基棕榈酸酯用途

4-甲基伞形花序基棕榈酸酯是检测人类白细胞中酸性脂肪酶的一种极好的荧光团。酸度和溶剂对其荧光有重要影响。4-甲基伞形烯丙基棕榈酸酯主要以中性分子形式存在,在近中性水溶液中可在445nm处产生强荧光,在弱碱溶液中主要以阴离子形式存在,可在445 nm处产生较强荧光[1][2]。

Geotrichum candidum NRRL Y-553 lipase: purification, characterization and fatty acid specificity.

Lipids 26(10) , 831-6, (1991)

Lipases from Geotrichum candidum NRRL Y-553 are of interest because of their unique specificity for cis-9-unsaturated fatty acids relative to both stearic and palmitic acids. The lipases were partiall...
