Characteristic secondary metabolites, including flavonoids, theanine and caffeine, are important components of Camellia sinensis, and their biosynthesis has attracted widespread interest. Previous studies on the biosynthesis of these major secondary metabolites using next-generation sequencing technologies limited the accurately prediction of full-length (FL) splice isoforms. Herein, we applied...

Background Nutritional interventions to improve physical regeneration after exercise are usual practice among recreational and professional athletes. Frequent strategies include rehydration, in addition to supplementation with macronutrients to replenish depleted glycogen stores, or to support muscle growth and/or maintenance. Physically challenging exercise results in a significant activation ...

this paper deals with the extraction of l-theanine containing aliquat 336 as a carrier and cyclohexane as solvent across bulk liquid membrane. the optimum operation condition are as follows: extraction time of 150 min, initial concentration of theanine in the feed phase is 1.8 g/l, the carrier concentration is 0.5 m, the ion of the receiving phase is 0.2 m nacl of na2hpo4-nah2po4 buffer solutio...

BACKGROUND We previously demonstrated the functional expression in newborn rat neocortical astrocytes of glutamine transporter (GlnT = slc38a1) believed to predominate in neurons over astroglia in the brain. In order to evaluate the possible role of this transporter in neurogenesis, we attempted to establish stable transfectants of GlnT in mouse embryonal carcinoma P19 cells endowed to prolifer...

This study discusses the genetic mutations that have a significant association with economically important traits would benefit tea breeders. The purpose of this was to analyze leaf quality and SNPs in quality-related genes plant collection 20 mutant genotypes growing without nitrogen fertilizers. Leaf N-content, catechins, L-theanine, caffeine contents were analyzed dry leaves via HPLC. Additi...
