General description

Methyl palmitate is a fatty acid methyl ester (FAME) that occurs naturally in crude palm oil and walnut. It is one of the FAME components of biodiesel fuel produced by the transesterification of triglyceride oil and a primary alcohol.

Application

Methyl palmitate can be used as an additive in food and cosmetic industries for the stabilization of fats and oil products by slowing down the auto-oxidation of unsaturated fatty acids.

Packaging

4, 8 kg in poly drum
1 kg in poly bottle

Biochem/physiol Actions

Methyl palmitate has anti-inflammatory and anti-fibrotic effect. Methyl palmitate prevents bleomycin-induced lung inflammation and fibrosis in rats, by inhibiting NF-κB . Methyl palmitate also prevents CCl4-induced liver fibrosis linked to reduced TGF-β .

Perivascular adipose tissue (PVAT)-derived relaxing factor (PVATRF) significantly regulates vascular tone. Its chemical nature remains unknown. We determined whether palmitic acid methyl ester (PAME) was the PVATRF and whether its release and/or vasorelaxing activity decreased in hypertension. Using superfusion bioassay...
