The Miller–Urey experiment applied an energy gradient to a soup of water, methane, ammonia, and hydrogen.
This produced a smorgasbord of organic compounds, nearly all of which were the building blocks of life on Earth.
It's possible that applying energy to a different soup would produce different results - but all of the chemicals I listed are incredibly common across the universe.
Given that, if life exists somewhere else in the universe, it's incredibly likely that it will be quite similar, in chemical composition, to life on Earth.
