Amino acid, peptide and protein analysis is one of the most important techniques in life science researches. Normally, the analysis of amino acids, peptide and protein in the sample is a complex process, and amino acid, peptide & protein standards are essential to obtain accurate and reliable results. Amino acid, peptide and protein standards are reference materials and physical standards. Depending on the testing requirements, the amino acid, peptide & protein standards can be a single component or a mixture of several different substances, but they all have a high purity.
Amino acid, peptide & protein standards play important roles in the field of amino acid, peptide and protein analysis, which are commonly used in calibration instruments, qualitative analysis, quantitative analysis and others. Commonly used amino acid, peptide & protein standards include L-alanine, L-asparagine, L-leucine, glycine, L-lysine, lactoferrin and others.
Analysis of amino acid, peptide and protein in food: Amino acid, peptide and protein are common additives in food, but the body cannot absorb and use too many of them. Excessive intake of certain amino acid, peptide or protein will break the body's absorption of other amino acid, peptide or protein, which can affect the absorption balance and lead to nutritional imbalance. Therefore, it is necessary to use amino acid, peptide & protein standards to analyze the types and contents of amino acid, peptide & protein in food. For example, glycine is an important sweetener in food. Based on glycine standard solution, the content of glycine in dairy products can be determined by high-performance liquid chromatography with pre-column derivation. In addition, this method has the advantages of high efficiency, high accuracy and good selectivity, which is widely used in the food field.
Analysis of amino acid, peptide and protein in medical field: Changes in the types and content of amino acid, peptide and protein in living organisms are often associated with certain diseases. In the field of medicine, the determination of amino acid, peptide and protein types and contents in biological samples by amino acid, peptide & protein standards can be used to diagnose some diseases. For example, when liver failure occurs, the content of aromatic amino acids in plasma increases, while the content of isoleucine, leucine and valine decreases. Therefore, liquid chromatography can be used to diagnose the patient's condition by comparing and calculating the peak position and peak area of the amino acid standards.
Others: In addition to the above two fields, amino acid, peptide & protein standards can also be used in other fields, including the determination of amino acid, peptide and protein content in feed and health products, the study of the mechanism of operation of living organisms and other fields.
