Novel Physiological Functions of Branched-Chain Amino Acids.
نویسندگان
چکیده
Branched-chain amino acids (BCAAs) are essential amino acids for humans and are major building blocks of proteins. Recent studies indicate that BCAAs act not only as components of proteins, but also as nutrasignals. In this review, we summarize the findings of recent studies investigating the physiological functions of BCAAs in the regulation of protein and glucose metabolism and brain function.

On the current study the effects of reducing branched-chain amino acids (BCAA) in diets of Sobaity sea bream in a constant level (40%) on growth and nutritional indices, pancreatic enzymes activity, whole body chemical proximate and amino acids, was assessed. This experiment was conducted in Marine Fish Research Station of Imam Khomeini harbor during July and August of 2014. For these purposes,...
متن کاملA Classic Case of Maple Syrup Urine Disease and a Novel Mutation in the BCKDHA Gene
Background: Maple syrup urine disease (MSUD) is an inherited branched-chain amino acid metabolic disorder caused by the deficiency in the branched-chain alpha-keto acid dehydrogenase (BCKD) complex. In MSUD, elevation of the branched-chain amino acids, such as alpha-keto acid and alpha-hydroxy acid, occurs due to the BCKDC gene deficiency, appearing in the blood, urine, and cerebrospinal fluid,...

Background& purpose: Today, among athletes, the use of amino acid supplements with the aim of reducing muscle injuries is more important than in the past. the aim of this study was to survey the effect of branched chain amino acids (BCAA) consumption before exhaustive exercise along with 1-month vitamin E supplementation on lactate dehydrogenase (LDH) and creatine kinase (CK) levels of active f...
متن کاملA STUDY OF ULTRASONIC ABSORPTION OF SOME AMINO ACIDS AND THEIR MIXTURES AT PHYSIOLOGICAL pH
In this paper, the ultrasonic absorption of amino acids was measured using a small cylindrical resonator at physiological pH and 25°C and a concentration of 0.1. M. The absorption of mixtures of some amino acids was also measured. In the case of cysteine-histidine, the absorption of mixtures is much larger (more than twice) than the summation of absorption of the individual amino acid. This...
