Creative Proteomics can provide the UPLC-MS/MS method to analyze the content and activity level of L-Asparagine, and obtain a highly sensitive and more accurate analysis report of L-Asparagine and related threonine metabolites. This detection method does not require derivatization, can simplify the sample analysis process, combines the high separation ability of chromatogram for complex samples and the high selectivity and high sensitivity of mass spectrometry, greatly improves the detection sensitivity and ensures the reliability of qualitative and quantitative results. It can quickly obtain more accurate experimental results to help customers speed up the application of L-Asparagine in the field of food nutritional supplements and biochemical reagents.

Overview

L-Asparagine is one of the 20 amino acids that make up biological proteins, and is also a component of some foods and medicines. Although it is a non-essential amino acid, it still has an active role in maintaining the human nervous system and metabolism. L-Asparagine is a non-essential amino acid, which participates in the metabolic control of nerve and brain tissue cell function. If it is lacking, it will affect development and can regulate the metabolic function of brain and nerve cells. In the food industry, it is a good nutritional supplement that can be added to various refreshing beverages; in the chemical industry, it is used to synthesize organic raw materials or pharmaceutical intermediates. It can be used as a raw material for synthetic resins and as a nutritional additive for cosmetics. Wait. L-Asparagine is a natural product found in various beans and so on. With the rapid development of analytical technology, the autosampler and high-speed detector of UHPLC can meet the needs of high-throughput sample detection and obtain high-speed and high-resolution analysis reports.
