Application
- A Color Indicator Based on 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium Bromide (MTT) and a Biodegradable Poly(ester amide) for Detecting Bacterial Contamination.: This study developed a biodegradable poly(ester amide) containing L-Alanine used with MTT for the detection of bacterial contamination, highlighting its potential in health-related applications (Franco et al., 2024).
- Randomized Trial to Assess the Safety and Tolerability of Daily Intake of an Allulose Amino Acid-Based Hydration Beverage in Men and Women.: Investigates the impact of a daily hydration beverage supplemented with L-Alanine among other amino acids on hydration and nutrient uptake in humans, emphasizing its safety and efficacy (Bloomer et al., 2024).
- Comparison of methods for the NMR measurement of motionally averaged dipolar couplings.: This study utilizes L-Alanine samples to compare NMR methods for measuring dipolar couplings, contributing to the improvement of NMR spectroscopy techniques (Southern et al., 2024).
