Your body absorbs amino acids from your digestive tract into your bloodstream. Plant and animal proteins are made up of about 20 common amino acids. Amino acids are "essential," which means you ...

Each protein is a molecule made up of different combinations of 20 types of smaller, simpler amino acids. Protein molecules are long chains of amino acids that are folded into a three-dimensional ...

Scientists have long believed they understood how life’s genetic code evolved, but new research upends that assumption. By ...

Bennu’s parent asteroid, which formed around 4.5 billion years ago, seems to have been home to pockets of liquid water.

Scientists found 11 minerals in Bennu samples, including calcite, halite, and sylvite, that form when water with dissolved ...

In other words, Bennu's samples provide further evidence that life's building blocks formed early in the solar system and ...

Hidden within the genetic code lies the "triplet code," a series of three nucleotides that determine a single amino acid. How did scientists discover and unlock this amino acid code? Once the ...

The scientists also found tiny crystals of rare salt minerals called halite and sylvite within Bennu's dust particles. These ...
