Methohexital is only found in individuals that have used or taken this drug. It is an intravenous anesthetic with a short duration of action that may be used for induction of anesthesia. [PubChem]Methohexital binds at a distinct binding site associated with a Cl- ionopore at the GABAA receptor, increasing the duration of time for which the Cl- ionopore is open. The post-synaptic inhibitory effect of GABA in the thalamus is, therefore, prolonged.

Methylmalonylcarnitine

(2R)-3-{[(2R)-1-carboxy-3-(trimethylazaniumyl)propan-2-yl]oxy}-2-methyl-3-oxopropanoic acid

C11H20NO6 (262.129056)


Methylmalonylcarnitine is an acylcarnitine. More specifically, it is an methylmalonic acid ester of carnitine. Acylcarnitines were first discovered more than 70 year ago (PMID: 13825279). It is believed that there are more than 1000 types of acylcarnitines in the human body. The general role of acylcarnitines is to transport acyl-groups (organic acids and fatty acids) from the cytoplasm into the mitochondria so that they can be broken down to produce energy.  This process is known as beta-oxidation. According to a recent review [Dambrova et al. 2021, Physiological Reviews], acylcarnitines (ACs) can be classified into 9 different categories depending on the type and size of their acyl-group: 1) short-chain ACs; 2) medium-chain ACs; 3) long-chain ACs; 4) very long-chain ACs; 5) hydroxy ACs; 6) branched chain ACs; 7) unsaturated ACs; 8) dicarboxylic ACs and 9) miscellaneous ACs. Short-chain ACs have acyl-groups with two to five carbons (C2-C5), medium-chain ACs have acyl-groups with six to thirteen carbons (C6-C13), long-chain ACs have acyl-groups with fourteen to twenty once carbons (C14-C21) and very long-chain ACs have acyl groups with more than 22 carbons. Methylmalonylcarnitine is therefore classified as a short chain AC. As a short-chain acylcarnitine methylmalonylcarnitine is a member of the most abundant group of carnitines in the body, comprising more than 50\\% of all acylcarnitines quantified in tissues and biofluids (PMID: 31920980). Some short-chain carnitines have been studied as supplements or treatments for a number of diseases, including neurological disorders and inborn errors of metabolism. In particular methylmalonylcarnitine is elevated in the blood or plasma of individuals with methylmalonyl-coa epimerase deficiency/methylmalonic acidemia (PMID: 27699154, PMID: 17279485), familial mediterranean fever (PMID: 29900937), and cobalamin C deficiency (PMID: 25367534). It is also decreased in the blood or plasma of individuals with melanoma (PMID: 30830422) and intracerebral hemorrhage (PMID: 29265114). Methylmalonylcarnitine is elevated in the urine of individuals with methylmalonyl-coa epimerase deficiency/methylmalonic acidemia (PMID: 27699154, PMID: 17279485). Carnitine acetyltransferase (CrAT, EC:2.3.1.7) is responsible for the synthesis of all short-chain and short branched-chain acylcarnitines (PMID: 23485643). The study of acylcarnitines is an active area of research and it is likely that many novel acylcarnitines will be discovered in the coming years. It is also likely that many novel roles in health and disease will be uncovered. An excellent review of the current state of knowledge for acylcarnitines is available at [Dambrova et al. 2021, Physiological Reviews].

Jacquinelin, also known as 11,13-dihydro-8-deoxylactucin or jacquilenin, is a member of the class of compounds known as gamma butyrolactones. Gamma butyrolactones are compounds containing a gamma butyrolactone moiety, which consists of an aliphatic five-member ring with four carbon atoms, one oxygen atom, and bears a ketone group on the carbon adjacent to the oxygen atom. Jacquinelin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa).

Phosphatidylglycerol

C8H23O7P (262.1181338)


Phosphatidylglycerol is a member of the class of compounds known as glycerophosphates. Glycerophosphates are compounds containing a glycerol linked to a phosphate group. Phosphatidylglycerol is soluble (in water) and a moderately acidic compound (based on its pKa). Phosphatidylglycerol can be found in a number of food items such as green bell pepper, fig, papaya, and carrot, which makes phosphatidylglycerol a potential biomarker for the consumption of these food products. Approximately 98\\% of alveolar wall surface area is due to the presence of type I cells, with type II cells producing pulmonary surfactant covering around 2\\% of the alveolar walls. Once surfactant is secreted by the type II cells, it must be spread over the remaining type I cellular surface area. Phosphatidylglycerol is thought to be important in spreading of surfactant over the Type I cellular surface area. The major surfactant deficiency in premature infants relates to the lack of phosphatidylglycerol, even though it comprises less than 5\\% of pulmonary surfactant phospholipids. It is synthesized by head group exchange of a phosphatidylcholine enriched phospholipid using the enzyme phospholipase D .
