Amino acids are the fundamental building blocks of proteins and play central roles as intermediates in myriad metabolic pathways. In medical biochemistry, they are not only recognised for their ...

Researchers at the University of California, Santa Barbara, unveiled a new modular way to combine three mix-and-matchable molecular pieces into new amino acid derivatives using an engineered enzyme ...

Four billion years ago, the Earth looked very different than it does today, devoid of life and covered by a vast ocean. Over the course of millions of years, in that primordial soup, life emerged.

While humans have an esthetic liking for symmetry in everything, nature prefers asymmetric, single-handed forms when it comes to amino acids—the building blocks of proteins, and, by extension, all ...

The molecular machines that cells use to build proteins are backed by a billion years of evolution. In that time, these machines—ribosomes—have become exceptionally good at forging amide bonds between ...

Proteins are the molecular machines that make all living things hum. They stop deadly infections, heal cells, capture energy from the sun and so much more. Proteins are built by stringing together ...

The findings, which detail how amino acids shaped the genetic code of ancient microorganisms, shed light on the mystery of how life began on Earth. "You see the same amino acids in every organism, ...

Amino acids are the building blocks of protein. These molecules come together to form proteins. Your body uses them for many important functions, such as making hormones, building muscle, and ...
