Chemical Information
FooDB NameGlycerol 1-octadecanoate
DescriptionGlycerol 1-monostearate, also known as mag(18:0/0:0) or 1-octadecanoylglycerol, belongs to the class of organic compounds known as 1-monoacylglycerols. These are monoacylglycerols containing a glycerol acylated at the 1-position. Glycerol 1-monostearate is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
