Can the Skeletal Muscle Carnosine Response to Beta-Alanine Supplementation Be Optimized?
Frontiers in Nutrition, 2019 Carnosine is an abundant histidine-containing dipeptide in human skeletal muscle and formed by beta-alanine and L-histidine. It performs various physiological roles during exercise and has attracted strong interest in recent years with numerous ...

Muscle carnosine metabolism and β-alanine supplementation in relation to exercise and training [PDF]
, 2010 Carnosine is a dipeptide with a high concentration in mammalian skeletal muscle. It is synthesized by carnosine synthase from the amino acids L-histidine and beta-alanine, of which the latter is the rate-limiting precursor, and degraded by carnosinase ...

A Budding-Defective M2 Mutant Exhibits Reduced Membrane Interaction, Insensitivity To Cholesterol, And Perturbed Interdomain Coupling [PDF]
, 2017 Influenza A M2 is a membrane-associated protein with a C-terminal amphipathic helix that plays a cholesterol-dependent role in viral budding. An M2 mutant with alanine substitutions in the C-terminal amphipathic helix is deficient in viral scission. With

A Systematic Risk Assessment and Meta-Analysis on the Use of Oral β-Alanine Supplementation.
Advances in Nutrition, 2019 β-Alanine supplementation is one of the world's most commonly used sports supplements, and its use as a nutritional strategy in other populations is ever-increasing, due to evidence of pleiotropic ergogenic and therapeutic benefits.

Cross-Correlated Motions in Azidolysozyme [PDF]
arXiv, 2021 The changes in the local and global dynamics of azide-labelled Lysozyme compared with that of the wild type protein are quantitatively assessed for all alanine residues along the polypeptide chain. Although attaching -N$_3$ to alanine residues has been considered to be a minimally invasive change in the protein it is found that depending on the ...

The behavior of alanin in metabolism [PDF]
Experimental Biology and Medicine, 1908 Injection of 20 grams of i-alanin in a completely phlorhizinized dog resulted in the elimination of “extra sugar” in the urine to an amount equalling 18.8 grams, or 93 per cent.

How Hydrophobic Is Alanine? [PDF]
Journal of Biological Chemistry, 2003 By a number of measures, alanine is poised at the threshold between those amino acids that promote the membrane integration of transmembrane alpha-helices and those that do not. We have measured the preference of alanine to partition into the lipid-water interface region over the central acyl chain region of the endoplasmic reticulum (ER) membrane both
