Tryptophol
Tryptophol is an aromatic alcohol that induces sleep in humans. It is found in wine as a secondary product of ethanol fermentation. It was first described by Felix Ehrlich in 1912. It is also produced by the trypanosomal parasite in sleeping sickness. It forms in the liver as a side-effect of disulfiram treatment. Natural occurrences Tryptophol can be found in ''Pinus sylvestris'' needles or seeds. It is produced by the trypanosomal parasite (''Trypanosoma brucei'') in sleeping sickness (African trypanosomiasis). Tryptophol is found in wine and beer as a secondary product of ethanol fermentation (a product also known as congener) by ''Saccharomyces cerevisiae''. It is also an autoantibiotic produced by the fungus ''Candida albicans. It can also be isolated from the marine sponge ''Ircinia spiculosa''. Metabolism Biosynthesis It was first described by Felix Ehrlich in 1912. Ehrlich demonstrated that yeast attacks the natural amino acids essentially by splitting off carbon dio ...

Dictyoceratida is an order of sponges in the subclass Ceractinomorpha containing five families. Along with the Dendroceratida, it is one of the two orders of demosponges that make up the keratose or "horny" sponges, in which a mineral skeleton is minimal or absent and a skeleton of organic fibers containing spongin, a collagen Collagen () is the main structural protein in the extracellular matrix found in the body's various connective tissues.
