Dalatias licha liver was assayed for the presence of enzyme activity and lipidic composition. The enzymes alcohol dehydrogenase, glutamate dehydrogenase, glucose-6-phosphate dehydrogenase, lactate dehydrogenase, malate dehydrogenase, amidase, catalase, proteases (as class of enzymes), phosphate alcaline, esterase, lipase-esterase, leucine arylamidase, valine arylamidase, cystine arylamidase, trypsin, phosphatase acid, naphtol-AS-BI-phosphohydrolase, beta-galactosidase, beta-glucuronidase, and alpha-glucosidase were shown to be present in an active form. Several phospholipids (lysolecithins, sphingomyelines and lecithins) and neutral lipids (monoacylglycerols, fatty acids, triacylglycerols, cholesterol esters, vitamin A esters and carbonated chains) were detected, as well as hydrosoluble vitamins: niacin, pantothenic acid, riboflavin, thiamin, biotin and folic acid and the liposoluble vitamins, vitamin A and vitamin E. Herein it is also present an analysis on the evaluation of Dalatias licha visceral organs other than liver for its use in cosmetic, pharmaceutical, food, leather and other industrial purposes.
