Researchers in Russia unveiled a fresh approach to foresee gestational diabetes in pregnant women, a development highlighted by the Moscow State University press service. The discovery aims to give doctors a clearer signal early in pregnancy, helping families prepare and clinicians tailor monitoring and care.
In living beings, there are two mirror-image families of amino acids, known as L- and D-amino acids. They share the same chemical makeup, yet their three dimensional shapes differ. Most amino acids exist in the L-form, while about 1 percent of D-amino acids participate in regulating certain bodily processes. Notably, elevated levels of D-alanine have been linked to neurodegenerative conditions such as Alzheimer’s and Parkinson’s diseases, underscoring the potential importance of studying these molecules in pregnancy and fetal development.
Two years prior, a study reported a link between D-phenylalanine levels in pregnant women and the onset of diabetes during pregnancy. This condition, gestational diabetes, is relatively common and can pose challenges for both mother and child if not detected and managed properly, according to Vladimir Tishkov, who led the investigation. The finding sparked renewed interest in simpler screening methods for D-phenylalanine that could be used in routine obstetric care.
Historically, measuring D-phenylalanine required expensive and intricate liquid chromatography equipment, and each analytical column faced wear after roughly a hundred procedures. The researchers proposed a different route: a test based on an enzymatic reaction specific to D-amino acids. Enzymes like oxidases can interact with D-amino acids, producing hydrogen peroxide, a compound that is straightforward to detect. Remarkably, such a specialized enzyme appears to be encoded in the genomes of several extremophile microorganisms living in the White Sea, opening possibilities for accessible diagnostics. This enzymatic strategy could simplify testing and reduce costs, making it feasible to screen more pregnant individuals as part of routine prenatal care.
Following additional validation work, the team envisions the creation of an affordable, easy-to-use testing kit for D-phenylalanine that could be implemented in clinics and community health settings. If successful, this approach would complement existing screening practices, enabling earlier intervention and better management of gestational diabetes risk. The researchers emphasize that broader collaboration and real-world trials will be essential to translate the laboratory concept into a practical tool for clinicians and expectant families.

In related developments, investigators continue to explore the broader role of D- and L-amino acids in metabolic health, pregnancy outcomes, and fetal development. The evolving understanding of these molecules may influence future guidelines for prenatal nutrition, screening, and risk assessment. As science advances, the hope remains that approachable diagnostics will empower healthcare providers to protect the health of both mothers and babies, ensuring better outcomes across communities.
