摘要:The disclosure relates to methods of forming a dihydrochalcone using electrocatalytic dehydrogenation. In particular, the disclosure relates to methods of forming a dihydrochalcone electrocatalytically hydrogenating (ECH) a reactant compound over a catalytic cathode in a reaction medium having a non-alkaline pH value, thereby forming a dihydrochalcone product; wherein the reactant compound has a structure according to Formula (I). The method can be used to prepare dihydrochalcone sweeteners, such as, for example, naringin dihydrochalcone and neohesperidin dihydrochalcone.

摘要:The present disclosure provides methods for enhancing muscle protein synthesis in an individual in need of same. Specifically, the present disclosure provides methods for enhancing muscle protein synthesis by enhancing myofibrillar muscle protein synthesis. The method includes administering to the individual a mixed macronutrient composition having (i) an amount of whey protein that is not capable of enhancing myofibrillar protein synthesis when ingested by itself and (ii) free leucine. The composition comprises at least about 5.0 g total leucine per dose.

摘要:The present disclosure provides methods for enhancing muscle protein synthesis in an individual in need of same. Specifically, the present disclosure provides methods for enhancing muscle protein synthesis during periods of negative energy balance, or energy deficit. The methods include administering to an individual suffering from energy deficit a composition comprising protein in an amount from about 15 g to about 30 g during a time period selected from the group consisting of during exercise, post-exercise, and combinations thereof. The methods also include administering to an individual suffering from energy deficit a composition comprising protein during a time period selected from the group consisting of during exercise, post-exercise, and combinations thereof, wherein the protein is administered in a dose that is higher than doses typically recommended for individuals experiencing energy balance.

摘要:The present disclosure provides methods for enhancing muscle protein synthesis following physical exertion. In a general embodiment, a method for enhancing muscle protein synthesis following physical exertion is provided and includes administering to an individual a composition comprising from about 15 to about 35 g protein immediately following concurrent training. Programs for enhancing muscle adaptation resulting from concurrent training are also provided. The programs include providing a composition comprising from about 15 to about 35 g protein; and providing guidelines for consumption including a recommendation of the amount of the composition to consume immediately following concurrent training.
