Another reason is related to free fatty acids,
monoglycerides, and diglycerides which are in trace components of biodiesel (Tables 2 and 3).

Monoglyceride lipase-like enzymatic activity is responsible for hydrolysis of 2-arachidonoylglycerol in rat cerebellar membranes," Biochemical Pharmacology, vol.
Even though, this study did not determine the fatty acid content, it can be replaced by crude fat, as it is also known as the ether extract or the free lipid content, the lipid materials may include triglycerides, diglycerides,
monoglycerides, phospholipids, steroids, and free fatty acids (Association of American Feed Control Officials [AAFCO], 2014).
Holm, "cDNA cloning, tissue distribution, and identification of the catalytic triad of
monoglyceride lipase.
HVCO in this study did not show its antibacterial ability although it might contain
monoglyceride. This could be explained that, in this study, HVCO only contained a small amount of
monoglyceride, so it did not have much enough to inhibit bacteria.
The specific JME fuel properties that include density at 15[degrees]C, calorific value, flash point, cetane value, specific gravity at 15[degrees]C, viscosity at 40[degrees]C, water content, ash content, acid value,
monoglyceride, diglyceride, triglyceride, free glycerine, total ester content, and total glycerine contents were evaluated with a fuel property testing equipment built on the ASTM standards (D2624, D3828) and European standards (EN 14105) such as calorimeter, fuel test kit, and gas chromatograph (Shimadzu-GC-2010 Plus) fitted with a flame ionization detector FID2010 Plus and a capillary column of size 30 m x 0.25 mm x 0.25 [micro]m.
Fortin, "Eicosapentaenoic acid and docosapentaenoic acid
monoglycerides are more potent than docosahexaenoic acid
monoglyceride to resolve inflammation in a rheumatoid arthritis model," Arthritis Research and Therapy, vol.
(6) It was later shown in 1979 Welsh and May, that the fat portion of human milk was active upon standing because it contained lipases that converted "inactive" triglycerides into two free fatty acids and an "active"
monoglyceride. (7)
In the two-step process (
monoglyceride method) there are alcoholysis and esterification steps.
The alkyd resin was prepared via the
monoglyceride process.

Alkyd polymers were synthesized using the
monoglyceride process.
