В поисках перевода основных терминов, используемых для описания специфики биохимического состава пуэров, наткнулся на следующую аннотацию одной тайваньской работы.
название статьи Inhibitory Effects of Sichuan Brick Tea Extracts on Fatty Acid Synthase

суммируют свое исследование следующим образом:

Sichuan brick tea (Kang Zhuan) contains different tea polyphenols from those of green tea and black tea. The inhibition on Fatty acid synthase (E.C.2.1.3.85, FAS) by the extracts of brick tea is measured by inhibition kinetics. FAS has been reported as a potential new therapeutic target for both cancer and obesity. The results show that the inhibition included both reversible and irreversible processes. The optimal solvent for extracting FAS inhibitors is 50% ethanol. The extraction was achieved during 5 h in room temperature. The boiling water could extract about total 60% effective FAS inhibitors by two times extraction. The final efficiency is two-folds of that for green tea, but longer time is needed for the extraction. The inhibition of FAS by new brick tea was not stronger, and brick tea stored for several years showed the best inhibitory activity. More storage time led to a reduction in the inhibitory ability of brick tea. Howere, most of that ability can be maintained for over 20 a. It is seems that the storage over 30 a markedly weakened the ability of brick tea. The brick tea extracts inhibited the overall reaction of FAS in a mixed manner of competitive and noncompetetive with acetyl-C0A and malonyl-CoA. It inhibited the ketoacyl reduction of FAS weakly, which indicated that the ketoacyl reductase domain is not the main reacted site that brick tea extracts attracted. These results shows that the inhibitor in brick tea is different from that in green tea and black tea. It is proposed that the effective element in brick tea should be theabrownine (TB) whose inhibitory ability is higher than that of catechins and is close to that of theaflavins. The results exhibited prospects of brick tea for fat-reducing and anti-cancer applications.


Обратите внимание что под блэк ти здесь (если судить по китайскому оригиналу) понимаются как и положено китайские хунча. Таким образом вся статья рассказывает об особенностях хэйча, одним из славных представителей которых является канчжуань.

ЗЫ: биохимики где вы? помогите перевести основные термины!
