L-Alanine Analysis Service

Online Inquiry

L -alanine is the most widely used alanine species and is used in many applications such as daily chemicals, pharmaceuticals and nutraceuticals, food additives and feed. l -alanine can be identified and evaluated in samples by advanced analytical methods. Liquid chromatography/Gas chromatography-mass spectrometry (LC/GC-MS) separates amino acids based on their unique properties and displays the results as a function of the relative abundance of detected ions as a function of mass-to-charge ratio. l -Alanine can be accurately and rapidly evaluated by Creative Proteomics through LC/GC-MS technology.

Overview

L-Alanine is an important natural amino acid and is the most abundant amino acid in the blood. l-Alanine is closely related to glucose metabolism and is the main amino worker in the transamination reaction, which has important physiological functions. It is a nutritional supplement and is a major component of many compounded amino acid infusions. It can be supplied as a pharmaceutical intermediate and is the main raw material of vitamin B6. It can also be used as a food additive to improve the nutritional value of foods and to improve the taste of synthetic sweeteners.

Mass spectrometry is used in many different fields, for pure samples and complex mixtures. In combination with HPLC or GC, mass spectrometry can effectively separate and quantify l -alanine. creative Proteomics can provide L-Alanine content analysis services for those in all areas of biomedicine.
