What compound is abundant in deep-sea snailfish to stabilize proteins under extreme pressure?

Answer

Trimethylamine N-oxide (TMAO)

Deep-sea species have an abundance of the fmo3 gene, which produces trimethylamine N-oxide (TMAO). This chemical acts as a protein stabilizer counteracting the destructive effects of high pressure on cellular structures.
