Analytical Methods for Amino Acids
Research in science, food science, pharmaceutical development, and clinical diagnostics requires a complete understanding of protein structure and composition. Techniques like Amino Acid Analysis determine the ratio of amino acids to protein concentrations in assessed samples.
This blog explores these testing techniques and the laboratory instruments used.
What is Protein Amino Acid Analysis?
Protein Amino Acid Analysis is the method of analysing proteins through amino acids. This specific laboratory technique enables both the qualitative and quantitative detection of amino acids within proteins, peptides, and biological materials. Such analytical methods would allow scientists to evaluate protein purity levels and chemical structure.
Some main uses of this technique are as follows:
Protein Characterization: Identifying amino acid sequences and modifications.
Pharmaceutical and Biomedical Research departments: Verify the correct protein composition of drug substances through this method.
Food and Nutritional Science: The composition of amino acids in dietary supplements and food products must be tested.
Clinical and Diagnostic Research: The study of amino acids helps to understand metabolic disorders and disease-related investigations.
Techniques for Protein Amino Acid Analysis
Different methods of analysing amino acids are used according to the specimen type and analytical requirements, and each method has advantages.
Chromatography by Ion-Exchange (IEC)
Ion-exchange chromatography is the foundation of amino acid analysis because it is a primary and most used technique.
Charged differences serve as the basis for amino acid separation through this method.
The detection method includes post-column derivatisation using ninhydrin.
The method appears regularly throughout pharmacological and clinical research studies.
Liquid Chromatography with High Performance (HPLC)
It is a popular method because of its excellent resolution and sensitivity.
The detection performance can be improved through derivatisation procedures that precede or follow the column.
Amino acid testing lab
The Amino acid testing lab prefers this method because it efficiently separates numerous types of amino acids.
GC-MS, or gas chromatography-mass spectrometry
Derivatised samples and volatile amino acids require this method as their optimal choice.
The method provides outstanding performance for detecting amino acids through precise measurement.
The technique finds applications in analysing food products, medical substances, and environmental samples.
Mass spectrometry-liquid chromatography (LC-MS)
The technique serves as an adaptable method to evaluate amino acids with effectiveness.
The method shows the capability to identify regular and modified amino acid sequences.
Exact measurements for complex biological substances are quantified through this method.
These analytical procedures serve the scientific and industrial sectors because they generate exact and dependable data when assessing amino acids.
