Casein protein helps muscle growth and recovery, especially with resistance training. One serving of casein protein powder provides about 45% of your daily calcium needs. Consuming too much casein ...

One of the most elegant theories about the origins of life on our planet is that it was kick-started by a delivery from outer space. This idea suggests that prebiotic molecules—the building blocks of ...

Tryptophan, the essential amino acid behind the Thanksgiving myth that eating turkey can make you sleepy, has been found to exist on Bennu, a small asteroid that swings by our planet about every six ...

In a peer-reviewed analysis, scientists quantify amino acids before and after our “last universal common ancestor.” The last universal common ancestor (LUCA) is the single life form that branched into ...

For decades, amino acids have been added to medical formulations like insulin as stabilizers: these small molecules keep proteins (i.e. larger particles) from interacting in undesirable ways. And for ...

Researchers demonstrated how amino acids could spontaneously attach to RNA under early Earth-like conditions using thioesters, providing a long-sought clue to the origins of protein synthesis. This ...

Amino acids are absolutely essential to our health—and for life itself. They are the so-called “building blocks” of proteins. They play a key role in the growth, repair, and maintenance of almost ...

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 ...

Let’s be honest. The world of skincare can feel like a minefield, especially when you have melanin-rich skin and the risk of irritation, dark spots, and scarring are real. For Black women, chemical ...

The body can produce cysteine, making it a non-essential amino acid (essential amino acids have to be obtained through diet). In the present study, the researchers explored how cysteine affected ...
