Branched-chain amino acids (BCAAs) influence brain function by modifying large, neutral amino acid (LNAA) transport at the blood–brain barrier. Transport is shared by several LNAAs, notably the BCAAs and the aromatic amino acids (ArAAs), and is competitive. Consequently, when plasma BCAA concentrations rise, which can occur in response to food ingestion or BCAA administration, or with the onset...
BACKGROUND Athletes and active adults many times have the goal of improving/maintaining fitness while losing weight and this is best achieved by caloric restriction in combination with exercise. However, this poses a risk for lean tissue loss, which can limit performance. Thus, the purpose of this study was to determine the effectiveness of a branched-chain amino acid (BCAA) supplement, in conj...
Beta-aminoisobutyric acid (BAIBA) and branched-chain amino acids (BCAA) have recently received considerable attention because of their various health benefits. In this study, the hydrolysis characteristics chicken breast for 11 commercially proteolytic enzymes were studied to evaluate effect protease type, reaction pH (5-8), leaction time (2-24 h) enzyme concentration (0.25-8%), two combined pr...
Aim/hypothesis: Leucine, isoleucine and valine are branched chain amino acids (BCAA). BCAAs areamong the 9 essential amino acids and are associated with beneficial health effects. However, previous studies have reported strong associations between increased BCAA levels, obesity and metabolic diseases such as type 2 diabetes. The objective of this study is to investigate the association between ...
مکمل های غذایی مبحث نسبتا جدیدی در ورزش محسوب می شوند. به نظر می رسد که اطلاع رسانی و آگاه ساختن ورزشکاران و مربیان از آخرین اطلاعات موجود در زمینه استفاده از مکمل های ورزشی و مواد دارویی واثرات مثبت و زیانبار آنها روی عملکرد ورزشی و سلامت بدن که در چارچوب قوانین و مقررات کمیته بین المللیالمپیک است، وظیفه ای است که بر دوش متولیان امور ورزشی سنگینی می کند. یکی از انواع این مکملها که امروزه به می...
Most studies concerning the Ile requirement in pigs have been carried out using blood products as a protein source, and these have a relatively low Ile content relative to the other branched-chain AA (BCAA). There are indications that an excess supply of one BCAA can affect the utilization of the other BCAA. Little information is available concerning the Ile requirement in pigs when the supply ...
Emerging resistance to current antibiotics raises the need for new microbial drug targets. We show that targeting branched-chain amino acid (BCAA) biosynthesis using sulfonylurea herbicides, which inhibit the BCAA biosynthetic enzyme acetohydroxyacid synthase (AHAS), can exert bacteriostatic effects on several pathogenic bacteria, including Burkholderia pseudomallei, Pseudomonas aeruginosa, and...
Background Caffeine, conjugated linoleic acid (CLA), green tea and branched chain amino acids (BCAA) have shown to individually improve body composition in overweight and obese men and women. The purpose of this study was to investigate the effects of a multi-ingredient dietary supplement containing caffeine, CLA, green tea, and BCAA on body composition and abdominal fat mass in overweight and ...
The effects in vivo of physiologic increases in insulin and amino acids on myocardial amino acid balance were evaluated in conscious dogs. Arterial and coronary sinus concentrations of amino acids and coronary blood flow were measured during a 30-min basal and a 100-min experimental period employing three protocols: euglycemic insulin clamp (plasma insulin equaled 70 +/- 11 microU/ml, n = 6); e...
The branched-chain amino acids (BCAAs) leucine, isoleucine, and valine are elevated in maple syrup urine disease, heart failure, obesity, and type 2 diabetes. BCAA homeostasis is controlled by the mitochondrial branched-chain α-ketoacid dehydrogenase complex (BCKDC), which is negatively regulated by the specific BCKD kinase (BDK). Here, we used structure-based design to develop a BDK inhibitor,...
