L-Alanine Analysis Service

Online Inquiry


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.

Advantages of Our L-Alanine Analysis Service

Less time consumed in the experiment process

Absolute quantitative analysis of L-alanine

Differentiation of alanine isomers

LC-MS platforms make the detection more efficient

Provide complete data analysis systematically

Low cost and high repeatability

Service Workflow

Creative Proteomics provides extraction, identification, and analysis of L-alanine in samples. By LC-MS separation and detection, L-alanine can reach its peak at a specific time (retention time) due to its unique nature, and its content level can be obtained by comparing spectral analysis.
