Associations between plasma branched-chain amino acids, β-aminoisobutyric acid and body composition

Journal of Nutritional Science, 2016
Plasma branched-chain amino acids (BCAA) are elevated in obesity and associated with increased cardiometabolic risk. β-Aminoisobutyric acid (B-AIBA), a recently identified small molecule metabolite, is associated with decreased cardiometabolic risk ...

β-Aminoisobutyric acid (L-BAIBA) is a novel regulator of mitochondrial biogenesis and respiratory function in human podocytes

Scientific Reports, 2023
Podocytes constitute an external layer of the glomerular filtration barrier, injury to which is a hallmark of renal disease. Mitochondrial dysfunction often accompanies podocyte damage and is associated with an increase in oxidative stress and apoptosis.

Physiological competition of brain phenylalanine accretion: Initial pharmacokinetic analyses of aminoisobutyric and methylaminoisobutyric acids in Pahenu2−/− mice

Molecular Genetics and Metabolism Reports, 2015
Objective: Initial studies on the use of non-physiological amino acids (NPAAs) to block the accretion of Phe in the brain of Pahenu2−/− mice revealed that 2-aminoisobutyrate (AIB) and N-methyl-2-aminoisobutyrate (MAIB) were promising lead compounds whose

Metabolomic analysis of plasma from breast tumour patients. A pilot study

Journal of Public Health Research, 2021
Background: Patients at risk of breast cancer are submitted to mammography, resulting in a classification of the lesions following the Breast Imaging Reporting and Data System (BI-RADS®). Due to BI-RADS 3 classification problems and the great uncertainty

Synthesis of enantiomerically enriched (R)-13C-labelled 2-aminoisobutyric acid (Aib) by conformational memory in the alkylation of a derivative of L-alanine

Beilstein Journal of Organic Chemistry, 2011
The method of Kouklovsky and coworkers for the enantioselective alkylation of cyclic N-naphthoyl derivatives of amino acids was used to introduce a 13C label into one of the two enantiotopic methyl groups of 2-aminoisobutyric acid (Aib) by retentive ...

Effects of water deficit during maturation on amino acids and jujube fruit eating quality

Macedonian Journal of Chemistry and Chemical Engineering, 2014
Pear-jujube yield and fruit characteristics can be clearly modified   by a water deficit imposed during fruit maturation period. One essential (cystine (Cys-cys)) and seven non-essential (4-hydroxyproline (p-Hyp), α-aminoadipic acid (AADA), ornithine ...
