In a zero-oxygen environment, such as before slaughter, the protein is purple. Once butchered the myoglobin is exposed to oxygen; this triggers beef to turn bright red. Eventually, as meat rests in a ...
While oxidation did increase slightly with the 100g dose, it remained negligible compared to the muscle-building activity. The body is not torching that extra protein, it’s putting it to work.
The researchers also noted that whey protein may affect diastolic blood pressure when consuming more than 30 grams (g) of WPI per day, for 10 weeks, in people with a body mass index (BMI) of 25 to 30.

During homeostasis and regeneration, satellite cells, the resident stem cells of skeletal muscle, have distinct metabolic requirements for fate transitions between quiescence, proliferation and ...
Protein intake appears to support protein oxidation, which helps preserve muscle glycogen and indirectly enhances endurance performance. However, protein ingestion, whether alone or combined with CHOs ...
Current sports nutrition guidelines recommend distributing protein intake in multiple equal meals throughout the day (1). This concept of protein distribution is primarily based on studies suggesting ...
For example, one study showed that when whey protein was stored at 113°F (45°C) for 15 weeks, there was a significant increase in oxidation, which led to the production of various compounds that ...
This study adds a fundamental new perspective to a long-standing question: What controls the repair of photosystem II (PSII), a key process in maintaining and optimizing photosynthesis? The work ...
