[Chemical nature of lachrymal products in the dolphin Tursiops truncatus].

Studies have been made on carbohydrate-protein complex (the ratio of carbohydrate to protein is equal to 1 : 2) in lachrymal products of the dolphin. It was shown that protein component includes 14 amino acids, in which diamino monocarboxylic acids amount to 58%. The ratio of the latter to monoamino dicarboxylic acids is equal to 4.
