Discover how therapeutic peptides act as biological messengers to treat disease, improve metabolism, and enhance immune ...

Amino acids are organic compounds that serve as the fundamental building blocks of proteins. They play a crucial role in the structure, function, and regulation of the body's tissues and organs. Amino ...

Amino acids have long been known to improve the stability and solubility of proteins. Amino acids might be added to insulin, for example, to maintain shelf-life and stop undesired chemical reactions ...

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 ...

Researchers are building out the repertoire of chemical reactions, using light. They report a method using photobiocatalysis to produce non-canonical (not naturally occurring) amino acids that are ...

Scientists have engineered bacteria to produce designer proteins by smuggling artificial amino acids, enabling precise drug delivery and multifunctional applications.

While cancer cells have been known to compete with each other for resources, it seems that they have also found a way to work together to gather nutrients. When exposed to amino acids, cells can ...

Lipid nanoparticles, or LNPs, best known as the delivery vehicle for the COVID-19 mRNA vaccines received by billions of people, are now at the center of a much larger medical revolution. Researchers ...

Can you have too much protein, do some people need more than others, and what are the best protein sources? A bariatric surgeon and a dietitian answer thes, and other key questions.
