Neurosporene
Neurosporene, also known as all-trans-neurosporene or 7,8-dihydro-ψ,ψ-carotene, is a member of the class of compounds known as carotenes. Carotenes are a type of unsaturated hydrocarbons containing eight consecutive isoprene units. They are characterized by the presence of two end-groups (mostly cyclohexene rings, but also cyclopentene rings or acyclic groups) linked by a long branched alkyl chain. Carotenes belonging form a subgroup of the carotenoids family. Thus, neurosporene is considered to be an isoprenoid lipid molecule. Neurosporene can be found in a number of food items such as chicory, poppy, silver linden, and towel gourd, which makes neurosporene a potential biomarker for the consumption of these food products. Neurosporene can be found primarily in blood and breast milk. Neurosporene is a carotenoid pigment. It is an intermediate in the biosynthesis of lycopene and a variety of bacterial carotenoids . Neurosporene is a triterpenoid carotenoid identified in human plasma, (PMID: 1416048), serum (PMID: 1416048), milk (PMID: 9164160), and tissues of the human eye (PMID: 11180970).

DG(14:0/16:1(9Z)/0:0)
DG(14:0/16:1(9Z)/0:0) is a diglyceride, or a diacylglycerol (DAG). It is a glyceride consisting of two fatty acid chains covalently bonded to a glycerol molecule through ester linkages. Diacylglycerols can have many different combinations of fatty acids attached at both the C-1 and C-2 positions. DG(14:0/16:1(9Z)/0:0), in particular, consists of one chain of myristic acid at the C-1 position and one chain of palmitoleic acid at the C-2 position. The myristic acid moiety is derived from nutmeg and butter, while the palmitoleic acid moiety is derived from animal fats and vegetable oils. Mono- and diacylglycerols are common food additives used to blend together certain ingredients, such as oil and water, which would not otherwise blend well. Dacylglycerols are often found in bakery products, beverages, ice cream, chewing gum, shortening, whipped toppings, margarine, and confections. Synthesis of diacylglycerol begins with glycerol-3-phosphate, which is derived primarily from dihydroxyacetone phosphate, a product of glycolysis (usually in the cytoplasm of liver or adipose tissue cells). Glycerol-3-phosphate is first acylated with acyl-coenzyme A (acyl-CoA) to form lysophosphatidic acid, which is then acylated with another molecule of acyl-CoA to yield phosphatidic acid. Phosphatidic acid is then de-phosphorylated to form diacylglycerol.Diacylglycerols are precursors to triacylglycerols (triglyceride), which are formed by the addition of a third fatty acid to the diacylglycerol under the catalysis of diglyceride acyltransferase. Since diacylglycerols are synthesized via phosphatidic acid, they will usually contain a saturated fatty acid at the C-1 position on the glycerol moiety and an unsaturated fatty acid at the C-2 position.
