Physicochemical Characterization of Creatine
Creatine is a naturally occurring guanidino compound. It is found in all types of muscle tissues, most of which are present in skeletal muscle and brain. Creatine in its free or phosphrylated forms plays an important role in the regulation and homeostasis of muscle energy metabolism. It appears to …

Physicochemical characterization of ten blackcurrant (Ribes nigrum) cultivars, their bioactivity related to type 2 diabetes and inflammation, and chemical changes after lactic acid fermentation
Blackcurrants (Ribes nigrum) are small, astringent berries that are not well known in the United States due to being banned for almost a century from the spread of a fungus that threatened the timber industry. However, new fungus resistant cultivars of blackcurrants have been created, and the high …
