Hexadecanal-d₅  (Synonyms: Palmitaldehyde-d₅)

Hexadecanal-d₅ (Palmitaldehyde-d₅) is deuterium labeled Hexadecanal. Hexadecanal (Palmitaldehyde) , a volatile long-chain aliphatic aldehyde, is emitted from human feces, skin, and breath. The receptor for hexadecanal(OR37B) is highly conserved across mammals. Hexadecanal may exert its effects by modulating functional connectivity between the brain substrates of social appraisal and the brain substrates of aggressive execution. Also, Hexadecanal is confirmed to be highly deterrent to the ant Lasius niger. Hexadecanal is promising for the research of startle responses and aggression^[1][2][3][4]
