Researchers say that the ice sheet naturally forms around the floodwaters Plays an important role. Because it’s like one “Lab CosmicA foot molecule Can accumulate and come closer to each other. Until chemical reactions occur.
From glycine to peptides
With the support of theoretical calculations, his team has already shown in 2020 – Galactic dust may form on grains. Why not imagine that amino acids can form even more complex molecules? For example, peptides.– I ‘ Simple, but it plays an important role
Maybe the process is not so easy. So theOccurs, said amino acids must be released from their water molecules to form a chain of amino acids. It requires energy, so it has a higher temperature than the dust grains found in the galaxy.
However, quantum chemical calculations can change the reaction under existing conditions in these environments(CO), carbon (C) and (NH3) Precursor to glycine – glycine (H) which does not contain a single water molecule2O) – occurs spontaneously by . To verify that this form of glycine could finally form peptides – without losing water … that it did not receive -, then had to resort to testing in an intense vacuum chamber.
From theory to experience
On a bromide diskThe researchers, 2.5 cm in diameter and 2 mm thick, deposited carbon monoxide, carbon and ammonia. Layer of a few dozen molecules. They cooled the whole thing to about 10 . Using one Infrared, they observed the formation of the glycine precursor they expected.
The researchers reheated the whole thing. At approximately 110 Kelvin, spectroscopyShows telltale signs of being a type It holds amino acids together in both short molecular chains of peptides and long chains of proteins. Again in stellar media, when can such warming occur a Begins to form. Or when dust falls on the surface of a planet, For example the comet.
In this new scenario of creation Proposed by Max Institute researchers So only relied on Atomic and molecular molecules are very abundant in the galaxy. This no longer requires a power input. It is now necessary to test whether peptides other than glycine-based peptides may be released.
