Cola detectives use protein testing to verify natural ingredients in premium soft drinks, detecting plant proteins in drinks claiming 'organic agave syrup and cola nut extracts'. Coca Cola products, without natural cola extract claims, have no detected protein, giving consumers a certificate of authenticity.
A study found that plants growing in contaminated soil near the Chernobyl Nuclear Power Plant adapt by altering certain proteins involved in cell signaling, allowing them to thrive in highly radioactive environments. Only about five percent of proteins were altered, suggesting a surprising resilience.
Researchers identified 20 barley proteins, 40 yeast proteins, and two corn proteins, revealing the largest portrait of the beer proteome. These findings may help brewers optimize fermentation processes and enhance beer's flavor and aroma.
Researchers found that plants growing in contaminated soil near Chernobyl have limited biochemical changes, suggesting adaptations to withstand radiation. These findings provide new insights into the mechanisms enabling plant survival in highly radioactive environments.
A new study has discovered that capsaicin, a compound found in chili peppers, can cause weight loss and fight fat buildup by triggering certain beneficial protein changes in the body. The research, published in ACS' Journal of Proteome Research, suggests that capsaicin may lead to new treatments for obesity.
Researchers analyzed bed bug saliva proteins to understand their role in feeding and potential medical applications. The study found unique enzymes that characterize the saliva profile of Cimex lectularius, a blood-feeding insect with over 250 million-year survival success.
A study found that calorie-restricted diets alter proteins in abdominal subcutaneous fat cells, which could serve as markers for improving or tracking therapy effects. Volunteers who lost an average of 21 pounds showed changes in protein levels, offering new insights into the mechanisms behind these diets.
A clinical trial found that eating about an ounce and a half of dark chocolate daily for two weeks reduced stress hormone levels and corrected other stress-related biochemical imbalances. This study provides strong evidence for the potential benefits of dark chocolate in reducing emotional stress.
