Green tea boosts production of detox enzymes, rendering cancerous chemicals harmless
...oncentrate might help some people strengthen their metabolic
defense against toxins capable of causing cancer. In a study of 42 people, the concentrate − composed of chemicals known as green tea catechins in amounts equal to that found in 8-16 cups of green tea − boosted production of the enzymes...

Taking a supplement of glycine helps prevent degenerative diseases such as arthrosis or osteoporosis
...hird of its residues. Mathematical analysis of the metabolic
route of the synthesis of the glycine, developed by the research group to which Patricia de Paz belongs, demonstrated that this amino acid should be considered an essential amino acid. The doctoral thesis carried out at the CMI and the UGR has sh...
New mechanism links smoking to lung damage

Why nectar-feeding bats need a 'power drink' to fly
.... Small nectar-feeding bats have among the highest metabolic
costs among mammals, and mostly eat a diet low in fat and protein but rich in sugars. Metabolising these sugars immediately they are consumed saves the costs of converting them to and from storage. In a second experiment, Voigt and Speakman measure...

Isoprene emission from plants -- a volatile answer to heat stress
...lar hypotheses suggests that isoprene protects the metabolic
processes in the leaf, in particular photosynthesis (the process by which plants use light energy to fix CO2 and produce their own food), against thermal stress. To test this hypothesis, scientists Katja Behnke and Jrg-Peter Schnitzler from the Insti...

Monell researchers find metabolic defect in liver that can lead to obesity
...s Center have identified a genetically-transmitted metabolic
defect that can lead to obesity in some individuals. The defect involves decreased production of liver enzymes needed to burn fat and may help to explain why some people become obese while others remain thin. The global obesity epidemic is thought ...
