Sentences with phrase «cyanide molecules»

Chemical reactions do slow down as the temperature drops, and according to standard calculations, the reactions that assemble cyanide molecules into amino acids and nucleobases should run a hundred thousand times more slowly at — 112 °F than at room temperature.

The proponents of vitamin B17 state that the cyanide molecule is locked in place by two other different molecules which neutralizes the dangerous cyanide molecule from harming normal cells.

The cyno is a synthetic, low - grade, low - quality and slightly toxic (cyanide - yes, it's bound to a cyanide molecule) form My dog has had a lot of digestive issues and I've done lots of research trying to find well made foods she can tolerate.

Not exact matches

The Saturn probe Cassini had detected a molecule of the right mass to be vinyl cyanide, but couldn't definitively identify the molecule's chemical makeup.

Orgel and his coworkers proposed these ideas in 1966, when he showed that frozen cyanide efficiently assembles into larger molecules.

Cyanide is a good candidate as a precursor molecule in the life - in - a-freezer model for several reasons.

Cyanide compounds are very reactive, so reactions on early Earth could have led to the more complex organic molecules that life needed (Geophysical Research Letters, DOI: 10.1029 / 2009gl040252).

Over a quarter - century, the frozen ammonia - cyanide blend had coalesced into the molecules of life: nucleobases, the building blocks of RNA and DNA, and amino acids, the building blocks of proteins.

Second, although cyanide is lethal to modern animals, it has a convenient tendency to self - assemble into larger molecules.

Meteors, comets or primordial ponds of hydrogen cyanide would still need to provide those molecules.

Meanwhile, hydrogen sulfide, which would have been released in huge amounts by volcanic eruptions, would have mostly stayed in the atmosphere, as the molecule is relatively insoluble in water, and therefore would not have had regular opportunities to interact with hydrogen cyanide.

Collisions between the particles and molecules in Earth's atmosphere produced nitrous oxide, a planet - warming greenhouse gas, and hydrogen cyanide, a crucial component for building DNA, the researchers propose May 23 in Nature Geoscience.

These complex organic molecules, two forms of cyanide and one chemically related compound, likely formed after the protoplanetary disk collapsed, the researchers say.

What the team has seen, however, are the chemical signs of three complex organic molecules in the cyanide family — an astronomical first, Öberg says.

The spacecraft's sensitive spectrometer was able to register the chemical signatures not only of water vapor but also of hydrogen cyanide, carbon monoxide, and carbon dioxide — all precursors of the more complex molecules that scientists think eventually gave rise to life on Earth.

Also, about half the cyanide groups along the rods reacted with neighbouring cyanides to form chemical bonds, preserving the shape of parallel ranks of molecules and stabilising the polymer.

Nearly identical molecules can have quite different scents — synthetic musk was accidentally created from a tweaking of TNT molecules in an explosives lab — and radically different structurescan smell similar, like the bitter almond tinge common to both marzipan and cyanide.

Looking through the data collected by the telescope, astronomers were able to detect a pattern of spikes for various life - supporting molecules: water, carbon monoxide, formaldehyde, methanol, dimethyl ether, hydrogen cyanide, sulfur oxide and sulfur dioxide.

Both this molecule and its simpler cousin hydrogen cyanide (HCN) were found in the cold outer reaches of the star's newly formed disk, in a region that astronomers believe is analogous to our own Kuiper Belt — the realm of icy planetesimals and comets beyond Neptune.

Astronomers have known that cold, dark interstellar clouds are very efficient factories of complex organic molecules — including a group of molecules known as cyanides.

ALMA has detected the complex organic molecule methyl cyanide in the outer reaches of the disk in the region where comets are believed to form.

Results with small, electrically charged cyanide ions and water molecules reveal that water zips around ions to a greater extent than expected.

At the coldest temperature tested, -438 °F, the molecules froze, with cyanide pointing its nitrogen end at the water.

The researchers plan to follow up with studies that include many water molecules and ions at once, as well as with more complex ions than cyanide.

The team used temperature - controlled photoelectron spectroscopy in EMSL, the DOE's Environmental Molecular Sciences Laboratory on the PNNL campus, to determine how tightly one cyanide ion and one to three water molecules interact at the very low temperature of -438 °F (12 Kelvin) and again at ambient temperature of 80 °F (equivalent to 300 Kelvin).

They range from the simplest — water, ammonia, methane, hydrogen cyanide and alcohols, including ethyl alcohol — to more complex molecules.

These chemicals contain glucose, sulfur and cyanide combined into a single molecule.
