Detailed explanation-1: -Ans . Amino acids are classified as non-polar, polar but uncharged, negatively charged, or positively charged based on the features of their different side chains.
Detailed explanation-2: -Currently, there are mainly two types of reagents available for use in analyzing amino acids, ninhydrin and o-phthalaldehyde. The former is for visible absorption detection and the latter is for fluorescence detection. The method most commonly used for separation is cation exchange chromatography.
Detailed explanation-3: -Present amino acid analysis methods include thin-layer chromatography, high-performance liquid chromatography, liquid chromatography-mass spectrometer, gas chromatography-mass spectrometry, capillary electrophoresis, nuclear magnetic resonance, and amino acid analyzer analysis.
