L-tyrosine is an amino acid that's often used in supplements to improve cognitive function affected by stress. Supplements containing L-tyrosine supplements may also help treat phenylketonuria (PKU).

Of the 20 essential amino acids, nine are actually essential. Of those nine, three are branch-chain amino acids (BCAAs). Leucine falls into both groups. All BCAAS are vital for building and ...

Dietary measures and medications may help reduce uric acid and manage gout. Gout can occur when blood uric acid levels are too high, causing crystals to form in the toes, feet, and other joints.

Proteins are biopolymers of amino acids (polypeptides), joined by peptide bonds, that are generated by ribosomes. The amino acid sequence, encoded by its gene, determines a protein’s structure ...

Uric acid is a waste product found in urine. If your body makes too much or doesn't eliminate enough of it, uric acid levels can become too high—a condition known as hyperuricemia. High uric acid ...

Fatty acids are organic acids with at least one carboxyl (-C(=O)OH, -COOH or -CO2H) group and a long carbon chain that can be joined by double bonds, as in unsaturated fatty acids, or single bonds ...

The specific determination referred to the standard GB/T 18654.11-2008. Tryptophan was not detected because it was destroyed during acid hydrolysis in the determination process. Free amino acid ...

Branched-chain amino acids (BCAAs), composed of leucine, isoleucine, and valine, are important essential amino acids in human physiology. Decades of studies have revealed their roles in protein ...
