Scientists Find a Strange Chemical Loop That May Have Helped Life Get Started
Space rocks like Bennu contain key genetic ingredients such as sugar, which they delivered in explosive fashion to provide early Earth with another source of life-friendly materials. Ribose is one such bio-essential sugar, some of which may have arrived from space before terrestrial processes could start making it.
A chemical interaction: The sugar ribose, which is important for RNA, is unstable, but can be protected from decay by borate. New laboratory experiments now show that ribose, in turn, can release and hold borate from minerals into the water. This could have allowed a self-promoting cycle on the early Earth.
