C44H59NO5 (681.4393)

Zucchini Factor A is a triterpenoid ester (esterified with p-aminobenzoic acid) that can be isolated from the seeds of zucchini, water melons, pumpkins and cucumbers. In some cases these multiflorane esters constitute up to 0.2\\% of the chemical constituents of these seeds. Zucchini factor A is a constituent of Cucurbita maxima and Cucurbita pepo. Constituent of Cucurbita pepo seeds. 7-Epizucchini factor A is found in fruits.

C37H64NO8P (681.4369)

PE(14:1(9Z)/18:4(6Z,9Z,12Z,15Z)) is a phosphatidylethanolamine (PE or GPEtn). It is a glycerophospholipid in which a phosphorylethanolamine moiety occupies a glycerol substitution site. As is the case with diacylglycerols, glycerophosphoethanolamines can have many different combinations of fatty acids of varying lengths and saturation attached at the C-1 and C-2 positions. Fatty acids containing 16, 18 and 20 carbons are the most common. PE(14:1(9Z)/18:4(6Z,9Z,12Z,15Z)), in particular, consists of one chain of myristoleic acid at the C-1 position and one chain of stearidonic acid at the C-2 position. The myristoleic acid moiety is derived from milk fats, while the stearidonic acid moiety is derived from seed oils. Phospholipids, are ubiquitous in nature and are key components of the lipid bilayer of cells, as well as being involved in metabolism and signaling.While most phospholipids have a saturated fatty acid on C-1 and an unsaturated fatty acid on C-2 of the glycerol backbone, the fatty acid distribution at the C-1 and C-2 positions of glycerol within phospholipids is continually in flux, owing to phospholipid degradation and the continuous phospholipid remodeling that occurs while these molecules are in membranes. PEs are neutral zwitterions at physiological pH. They mostly have palmitic or stearic acid on carbon 1 and a long chain unsaturated fatty acid (e.g. 18:2, 20:4 and 22:6) on carbon 2. PE synthesis can occur via two pathways. The first requires that ethanolamine be activated by phosphorylation and then coupled to CDP. The ethanolamine is then transferred from CDP-ethanolamine to phosphatidic acid to yield PE. The second involves the decarboxylation of PS.

3-octaprenyl-4-hydroxybenzoate is a member of the class of compounds known as polyprenylphenols. Polyprenylphenols are compounds containing a polyisoprene chain attached to a phenol group. 3-octaprenyl-4-hydroxybenzoate is practically insoluble (in water) and a weakly acidic compound (based on its pKa). 3-octaprenyl-4-hydroxybenzoate can be found in a number of food items such as pak choy, spinach, mango, and chervil, which makes 3-octaprenyl-4-hydroxybenzoate a potential biomarker for the consumption of these food products.
