El gra de blat no ho sap, ni ho sabrà mai. No era la seua intenció, perquè no en té. La seua essència inclou protegir el nitrogen per a la plàntula.

Japanese researchers have developed a compact tool to read amino acids’ molecular handedness through tiny electrical currents, which could help future space missions search for clues to life.

Si dues molècules són pràcticament idèntiques, per què la natura acaba afavorint-ne una? Per entendre aquest fenomen, que es coneix com a _homoquiralitat_ , podem fer un exercici d'imaginació amb un parell de sabates: la dreta i l'esquerra són imatges especulars l'una de l'altra –com si una fos el reflex de l'altra en un mirall–, però no es poden intercanviar perquè cadascuna encaixa amb un peu diferent. Amb algunes molècules, com els aminoàcids, passa el mateix: existeixen en dues formes que tenen la mateixa composició i estructura, però que no es poden superposar. Són les anomenades _molècules quirals_.

Glucagon plays a pivotal role in hepatic amino acid metabolism; acute high-protein diet feeding and diabetic condition both induce enhanced glucagon secretion. However, it remains unknown whether…

The analysis found correlated shifts in amino acids and phenolics, offering a new way to study vineyard-specific fruit composition

A large-scale study involving over 270,000 participants found that higher blood levels of the amino acid tyrosine may be associated with reduced male life expectancy by nearly a year. Researchers used genetic analysis techniques like Mendelian randomization to establish this link, suggesting that tyrosine could play a role in determining lifespan differences between genders. The study highlights how common dietary components might influence longevity, though further research is needed to confirm causality. While the findings are significant, they emphasize that individual health outcomes depend on complex interactions between genetics, lifestyle, and environmental factors. The results also raise questions about the potential impact of supplements containing tyrosine on long-term health, prompting experts to advocate for more nuanced approaches to nutritional interventions.

Symbiotic ammonia-oxidizing archaea in marine sponges are not strict specialists, but true "flexitarians": A team led by microbiologists Bettina Glasl and Katharina Kitzinger from the University of Vienna, in collaboration with partners from Australia, has shown that these microbes dine not only on ammonia but also on amino acids such as valine, leucine, and isoleucine - and presumably do that to communicate with their animal host. The findings shed new light on one of the oldest animal-microbe symbiotic relationships on Earth and point to a previously underestimated role played by archaea. The study was published in the prestigious journal Science Advances.

L-glutamine, an amino acid that occurs naturally in the body and plays an important role in digestion, has been studied as a potential way to ease side effects in other cancers.

Abstract. Humans and animals are unable to biosynthesize the so-called essential amino acids, which plants and their crops often lack in sufficient quantit

Arginine appears to help the immune system destroy cancerous or infected cells. It is readily available in many high-protein foods.

The reason animal proteins trigger the release of the cancer-promoting growth hormone IGF-1 more than plant proteins may be because the relative ratios of amino acids in animal proteins more closely r...
