Ninhydrin is derived from the combination of "nin" (from the prefix "ninhydrin" itself, which is a modification of the word "hydrin") and "hydrin" (from the Greek "hydor", meaning water). The term refers to a chemical compound that reacts with amino acids and proteins, often used in biochemical analysis, particularly in detecting fingerprints. The name reflects its chemical structure and properties related to water.
