Tortoise and Turtle Extension Lifespan in Related to Branched-Chain and Sulphur Contain Amino Acids: A Review

Branched-Chain Amino Acids: Metabolism, Physiological Function, and Application Branched-Chain Amino Acids: Enzyme and Substrate Regulation

The three branched-chain amino acids (BCAAs) are the most hydrophobic of the amino acids and play crucial roles in determining the structures of globular proteins as well as the interaction of the transmembrane domains of membranous proteins with phospholipid bilayers. However, the three BCAAs do not behave identically. In terms of protein secondary structure, valine and isoleucine exhibit a de...

Branched Chain Amino Acids: Beyond Nutrition Metabolism.

Branched chain amino acids (BCAAs), including leucine (Leu), isoleucine (Ile), and valine (Val), play critical roles in the regulation of energy homeostasis, nutrition metabolism, gut health, immunity and disease in humans and animals. As the most abundant of essential amino acids (EAAs), BCAAs are not only the substrates for synthesis of nitrogenous compounds, they also serve as signaling mole...

Enzymic determination of branched-chain amino acids.

Transamination of branched-chain amino acids to (alpha-oxoglutarate, catalyzed by leucine aminotransferase coupled to the glutamate dehydrogenase reaction, is used in an enzymic assay for determination of branched-chain amino acids in serum and tissue homogenates. The coefficients of variation of the method within-day and day-to-day are 2.4 and 6.5%, respectively. Analytical recovery of physiol...

Introduction to symposium on branched-chain amino acids in exercise.

The use of protein and amino acids to improve muscle mass and physical performance in athletes has been a topic of considerable interest to sports nutritionists. Behind this application, however, are a number of issues of current scientific interest. First is the question of how physical training modifies muscle protein synthesis and breakdown, and whether and how changes in protein and amino a...
