Scientists have uncovered how aging alters tryptophan metabolism in the brain, linking a longevity protein to ...

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 ...

Photosynthesis refers to the fundamental biological process of the conversion of light energy into chemical energy by chlorophyll (a green pigment) containing plants. This seemingly routine process in ...

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 ...

This review illustrates amino acid metabolic reprogramming in breast cancer, highlighting its role in tumor progression and clinical applications, including diagnostic imaging, targeted therapies, ...

Scientists uncovered how the amino acid leucine enhances mitochondrial efficiency by preserving crucial proteins that drive energy production. By downregulating the protein SEL1L, leucine prevents ...

A new study by researchers from North Carolina State University shows that protein sources in an animal’s diet can have major effects on both the population and function of the microscopic life within ...

In mice, limited intakes of one specific essential amino acid can slow the effects of aging and even extend their lifespan, ...

Tesamorelin is a synthetic 44–amino acid analog of growth hormone–releasing hormone (GHRH) that has attracted attention outside the experimental domain for its potential as a research tool. This ...

A recent study published in Advanced Energy and Sustainability Research explores how nutritional amino acids (AAs)—both essential (EAAs) and nonessential (NEAAs)—affect the breakdown of polystyrene ...

As people grow older, the same brain chemistry that once supported sharp thinking and stable mood can quietly start to work ...
