Allylestrenol
Allylestrenol is only found in individuals that have used or taken this drug. It is a synthetic steroid with progestational activity. [PubChem]Allylestrenol is similar in structure and function to progesterone. Progesterone shares the pharmacological actions of the progestins. Progesterone binds to the progesterone and estrogen receptors. Target cells include the female reproductive tract, the mammary gland, the hypothalamus, and the pituitary. Once bound to the receptor, progestins like Progesterone will slow the frequency of release of gonadotropin releasing hormone (GnRH) from the hypothalamus and blunt the pre-ovulatory LH (luteinizing hormone) surge. In women who have adequate endogenous estrogen, progesterone transforms a proliferative endometrium into a secretory one. Progesterone is essential for the development of decidual tissue and is necessary to increase endometrial receptivity for implantation of an embryo. Once an embryo has been implanted, progesterone acts to maintain the pregnancy. Progesterone also stimulates the growth of mammary alveolar tissue and relaxes uterine smooth muscle. It has little estrogenic and androgenic activity.

2-hydroxystearate
2-Hydroxystearic acid (CAS: 629-22-1), also known as 2-hydroxystearate or 2-hydroxyoctadecanoic acid, is a member of the class of compounds known as long-chain fatty acids. Long-chain fatty acids are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. The chain of 2-hydroxystearic acid bears a hydroxyl group. 2-Hydroxystearic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). 2-Hydroxystearic acid can be found in feces. 2-Hydroxystearic acid can be synthesized from octadecanoic acid, and can be synthesized into 2-hydroxystearoyl-CoA and N-2-hydroxystearoylsphingosine.

In humans fatty acids are predominantly formed in the liver and adipose tissue, and mammary glands during lactation. 9-Hydroxyoctadecanoic acid (9-HSA) is an HDAC1 inhibitor that inhibits ～66.4\% HDAC1 enzymatic activity at 5 μM. 9-Hydroxyoctadecanoic acid shows anticancer activity[1].

MG(0:0/14:1(9Z)/0:0)
MG(0:0/14:1(9Z)/0:0) is a monoacylglyceride. A monoglyceride, more correctly known as a monoacylglycerol, is a glyceride consisting of one fatty acid chain covalently bonded to a glycerol molecule through an ester linkage. Monoacylglycerol can be broadly divided into two groups; 1-monoacylglycerols (or 3-monoacylglycerols) and 2-monoacylglycerols, depending on the position of the ester bond on the glycerol moiety. Normally the 1-/3-isomers are not distinguished from each other and are termed alpha-monoacylglycerols, while the 2-isomers are beta-monoacylglycerols. Monoacylglycerols are formed biochemically via release of a fatty acid from diacylglycerol by diacylglycerol lipase or hormone sensitive lipase. Monoacylglycerols are broken down by monoacylglycerol lipase. They tend to be minor components only of most plant and animal tissues, and indeed would not be expected to accumulate because their strong detergent properties would have a disruptive effect on membranes. 2-Monoacylglycerols are a major end product of the intestinal digestion of dietary fats in animals via the enzyme pancreatic lipase. They are taken up directly by the intestinal cells and converted to triacylglycerols via the monoacylglycerol pathway before being transported in lymph to the liver. Mono- and Diglycerides are commonly added to commercial food products in small quantities. They act as emulsifiers, helping to mix ingredients such as oil and water that would not otherwise blend well. MG(0:0/14:1(9Z)/0:0) belongs to the family of monoradyglycerols, which are glycerolipids lipids containing a common glycerol backbone to which at one fatty acyl group is attached. Their general formula is [R1]OCC(CO[R2])O[R3]. MG(0:0/14:1(9Z)/0:0) is made up of one 9Z-tetradecenoyl(R2).
