Catalytic production of alanine from waste glycerol.
Angewandte Chemie, 2019Chemical synthesis of amino acids directly from biomass feedstock is rare. Herein, we report a one-step protocol to convert crude glycerol from the biodiesel industry into 43% alanine over a Ru1Ni7/MgO catalyst.

Abstract: Alanine transport and the role of alanine amino‐transferase in the synthesis and consumption of glutamate were investigated in the preparation of rat brain synaptosomes. Alanine was accumulated rapidly via both the high‐and low‐affinity uptake systems.

β-Alanine is rapidly developing as one of the most popular sport supplements used by strength/power athletes worldwide. The popularity of β-alanine stems from its unique ability to enhance intramuscular buffering capacity and thereby attenuating fatigue.

Amperometric Alanine Electrode
Analytical Letters, 1993Abstract An amperometric enzyme electrode for L-Alanine determination was developed. The probe is based on a platinum electrode which senses the hydrogen peroxide produced by the enzymatic reactions catalyzed by two enzymes: alanine aminotransferase (ALT) and glutamate oxidase.

Two complexes of alanine with water, alanine-(H2O)n (n = 1,2), have been generated by laser ablation of the amino acid in a supersonic jet containing water vapor and characterized using Fourier transform microwave spectroscopy. In the observed complexes, water molecules bind to the carboxylic group of alanine acting as both proton donors and acceptors.

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].

AbstractThe poem below presents a brief review of amino acid abbreviations and structures. Among the featured facts are the following: histidine has a pKa close to the normal pH of the cytosol and therefore is an effective intracellular buffer, the R group of isoleucine is hydrophobic, and many protein kinases add a phosphate at the ‐OH site of ...

Regulation of gluconeogenesis by alanine
Biochimica et Biophysica Acta (BBA) - General Subjects, 1974Abstract 1. 1. L -alanine and α-amino-isobutyric acid (0.5–10 mM) have been shown to stimulate glucose formation by isolated kidney tubules from fed and starved rats, with the substrates pyruvate, lactate, fructose, malate, fumarate, α-oxoglutarate and glycerol.

Alanine dehydrogenases in mycobacteria
Journal of Microbiology, 2019Since NAD(H)-dependent L-alanine dehydrogenase (EC 1.1.4.1; Ald) was identified as one of the major antigens present in culture filtrates of Mycobacterium tuberculosis, many studies on the enzyme have been conducted. Ald catalyzes the reversible conversion of pyruvate to alanine with concomitant oxidation of NADH to NAD+ and has a homohexameric ...

Combinatorial alanine-scanning
Current Opinion in Chemical Biology, 2001Combinatorial libraries of alanine-substituted proteins can be used to rapidly identify residues important for protein function, stability and shape. Each alanine substitution examines the contribution of an individual amino acid sidechain to the functionality of the protein.
