This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Structure and function of protein, Subject name: Biochemistry
Fluorescamine is used to detect 
Select and explain. 
A. Amino acids, B. Fatty acids, C. Glucose, D. Fructose
A: Amino acids
Answer: A: Amino acids 
Explanation: Fluorescence detectors are generally more sensitive than photometric ones. In addition, precolumn or postcolumn reactors have been used to chemically tag a compound with a fluorescent label for subsequent detection. For example, amino acids and other primary amines often are labeled with a dansyl or fluorescamine tag, followed by HPLC separation and fluorometric detection.
