The question of how life could have emerged is one of the most long-standing mysteries in science. In a new study, the ...

In this work, Liu et al. demonstrated a single-molecule technique to directly identify different proteinogenic amino acids and their enantiomers via accurate dynamic measurements of host-guest ...

Changing a certain amino acid in a molecular motor called Ncd, which was discovered at Duke, caused an "astonishing" result in the motor's behavior, said Sharyn Endow, lead author of the research ...

Amino acids can form in the frigid conditions of interstellar molecular gas clouds, new laboratory experiments show, providing further evidence that the basic building blocks of life as we know it ...

"The evidence for tryptophan in the Perseus molecular complex should encourage additional efforts to identify other amino acids in this region and in other star-forming regions," the scientists ...

However, these techniques either lack single-molecule resolution to interrogate each individual amino acid residue or require a large investment in equipment and lab space, driving the need for a ...

Each of life’s molecular building blocks (amino acids and sugars) has a twin—not an identical one, but a mirror image. Just like your right hand mirrors your left but will never fit ...

identifying it as a precursor molecule essential for such things as amino acids which, in turn, are crucial elements for the building blocks of proteins and life. "Understanding the production of ...

Glycine – CH 2 NH 2 COOH – is the simplest of all the 20 amino acids. Yi-Jehng Kuan of the National Taiwan Normal University and co-workers from the NASA Ames Research Center and the Polish Academy of ...
