Beta-alanine and tanning polymorphisms
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 19821. Beta-alanine is found in mycelial walls of mature tan, but not immature white, stage of Morchella esulenta, nor in any stage of a permanently white mutant. 2. Beta-alanine is also found in hydrolysed water-extracts of human hair, the concentration being higher in blond than in dark brown, and in pigmented than in unpigmented hair. 3.

Beta-alanine and adaptation in Drosophila
Journal of Insect Physiology, 1974Populations of Drosophila melanogaster show melanistic polymorphism. Adult melanization is inversely related to the rate of incorporation of beta-alanine into tanning cuticles. Light tan pigmentation is directly related to this incorporation. Beta-alanine induced tanning serves to protect pupae from ultraviolet light damage.

The combination of Fourier transform microwave spectroscopy in a pulsed supersonic jet with laser ablation has made beta-alanine amenable to a structural study in the gas phase. Two new conformers of beta-alanine have been identified together with the two previously observed by McGlone and Godfrey [J. Am. Chem. Soc. 1995, 117, 1043].

Beta-Alanine Supplementation in High-Intensity Exercise
2012Glycolysis involves the oxidation of two neutral hydroxyl groups on each glycosyl (or glucosyl) unit metabolised, yielding two carboxylic acid groups. During low-intensity exercise these, along with the remainder of the carbon skeleton, are further oxidised to CO(2) and water.

Beta-alanine distribution in the lobster, Homarus americanus
Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1975Abstract 1. 1. Whereas the distribution in lobster of γ-aminobutyric acid (GABA) was restricted to nerve and muscle tissues, that of beta-alanine (BA) was more widespread and uniform. 2. 2. In abdominal, thoracic and subesophageal nerve cords and in cleaned peripheral motor nerve fibers, the GABA-BA ratio was 2–5 : 1. 3. 3. In walking leg

Starting from porcine insulin, A1-glycine was substituted by beta-alanine. The blood sugar lowering effect of the new analogue in the rabbit is about 45% of that of insulin. The half-maximal binding to partially purified rat liver receptors is about 46%, to transformed human lymphocytes about 54%, compared to insulin.

The beta-alanine residue of the title compound, C(5)H(8)ClNO(3), has a ggt folded conformation, which is mainly stabilized through intermolecular N-H...O=C (amide-acid) and O-H...O=C (acid-amide) hydrogen bonds. In addition, a cis conformation is found for the Cl-CH(2)-C(=O)-NH torsion angle, which is associated with the presence of an intramolecular ...

The synthesis of poly-ß-alanine by a lipase catalyzed polycondensation reaction between ß-alanine esters is reported. The effect of different solvents, reaction temperatures and substrate/enzyme concentrations on polymer yield and degree of polymerization (DP) was determined.

beta-Alanine containing peptides: gamma-turns in cyclotetrapeptides.
Biopolymers, 1993In the present paper we describe the synthesis, purification, single-crystal x-ray analysis, solution conformational characterization, and conformational energy calculations of the cyclic tetrapeptide cyclo-(beta-Ala-L-Pro-beta-Ala-L-Val). The peptide was synthesized by classical solution methods and the cyclization of the free tetrapeptide was ...
