3-Methylindole
3-Methylindole, or skatole, belongs to the indole family and has a methyl substituent in position 3 of the indole ring. It occurs naturally in feces, beets, and coal tar, and has a strong fecal odor. Its name is derived from skato, the Greek word for dung. It exists as a white crystalline or fine powder solid, and it browns upon aging. 3-Methylindole is produced from tryptophan in the mammalian digestive tract where tryptophan is converted to indoleacetic acid, which decarboxylates to give the methylindole. These reactions are largely driven by the microbiota in the digestive tract. 3-Methylindole is soluble in alcohol and benzene and it gives violet color in potassium ferrocyanide (K4Fe(CN)6.3H2O) mixed with sulfuric acid (H2SO4). Skatole has a double ring system which displays aromaticity that comes from the lone pair electrons on the nitrogen. It is continuous (all atoms in the ring are sp2 hybridized), planar, and follows the 4n+2 rule because it has 10 pi electrons. In a 1994 report released by five top cigarette companies, skatole was listed as one of the 599 additives to cigarettes. This is because in low concentrations skatole has a flowery smell and is found in several flowers and essential oils, including those of orange blossoms, jasmine, and Ziziphus mauritiana. As a result, skatole/3-methylindole is used as a fragrance and fixative in many perfumes and as a general aroma compound for other applications. 3-Methylindole has been found to be a bacterial metabolite of members of the Clostridium (PMID: 18223109) and Lactobacillus (PMID: 16345702) families. Skatole functions as an insect attractant and is one of many compounds that are attractive to males of various species of orchid bees, which apparently gather the chemical to synthesize pheromones; it is commonly used as bait for these bees for study (PMID: 12647866). It is also known for being an attractant for the Tasmanian grass grub beetle (Aphodius tasmaniae). Skatole has also been shown to be an attractant to gravid mosquitoes in both field and laboratory conditions (PMID: 24242053). 3-methylindole, also known as skatol or 3-methyl-4,5-benzopyrrole, is a member of the class of compounds known as 3-methylindoles. 3-methylindoles are aromatic heterocyclic compounds that contain an indole moiety substituted at the 3-position with a methyl group. 3-methylindole is slightly soluble (in water) and an extremely weak acidic compound (based on its pKa). 3-methylindole is a very strong, animal, and civet tasting compound found in common beet and red beetroot, which makes 3-methylindole a potential biomarker for the consumption of these food products. 3-methylindole can be found primarily in feces and saliva. Skatole or 3-methylindole is a mildly toxic white crystalline organic compound belonging to the indole family. It occurs naturally in feces (it is produced from tryptophan in the mammalian digestive tract) and coal tar and has a strong fecal odor. In low concentrations, it has a flowery smell and is found in several flowers and essential oils, including those of orange blossoms, jasmine, and Ziziphus mauritiana. It is used as a fragrance and fixative in many perfumes and as an aroma compound. Its name is derived from the Greek root skato- meaning "dung". Skatole was discovered in 1877 by the German physician Ludwig Brieger (1849–1919). Skatole is also used by U.S. military in its non-lethal weaponry; specifically, malodorants . Skatole.

Creatine
Creatine, is a naturally occurring non-protein compound. It belongs to the class of organic compounds known as alpha amino acids and derivatives. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon), or a derivative thereof. Creatine is found in all vertebrates where it facilitates recycling of adenosine triphosphate (ATP). Its primary metabolic role is to combine with a phosphoryl group, via the enzyme creatine kinase, to generate phosphocreatine, which is used to regenerate ATP. Most of the human bodys total creatine and phosphocreatine stores are found in skeletal muscle (95\\\\\%), while the remainder is distributed in the blood, brain, testes, and other tissues. Creatine is not an essential nutrient as it is naturally produced in the human body from the amino acids glycine and arginine, with an additional requirement for methionine to catalyze the transformation of guanidinoacetate to creatine. In the first step of its biosynthesis glycine and arginine are combined by the enzyme arginine:glycine amidinotransferase (AGAT) to form guanidinoacetate, which is then methylated by guanidinoacetate N-methyltransferase (GAMT), using S-adenosyl methionine as the methyl donor. Creatine can also be obtained through the diet at a rate of about 1 gram per day from an omnivorous diet. A cyclic form of creatine, called creatinine, exists in equilibrium with its tautomer and with creatine. Clinically, there are three distinct disorders of creatine metabolism. Deficiencies in the two synthesis enzymes (AGAT and GAMT) can cause L-arginine:glycine amidinotransferase deficiency (caused by variants in AGAT) and guanidinoacetate methyltransferase deficiency (caused by variants in GAMT). Both disorders are inherited in an autosomal recessive manner. A third defect, creatine transporter defect, is caused by mutations in SLC6A8 and inherited in a X-linked manner. Creatine is widely used as a supplement by athletes. Its use can increase maximum power and performance in high-intensity anaerobic repetitive work (periods of work and rest) by 5 to 15\\\\\% (PMID: 24688272). Creatine has no significant effect on aerobic endurance, although it will increase power during short sessions of high-intensity aerobic exercise (PMID: 9662683).

Creatine is synthesized in the kidney, liver and pancreas from L-arginine, glycine and L-methionine. Creatine. CAS Common Chemistry.
