title: Changes in the fatty acid composition of Drosophila melanogaster during development and ageing.
abstract: In Drosophila melanogaster the saturated fatty acids increase in amount early in pupal development relative to the concentrations in late third instar larvae, then decline to the levels characteristic of one-day-old adults. Conversely, the monounsaturated fatty acids decline in content early in pupal development, then increase late in the pupal period. Lauric acid (12:0), myristic acid (14:0) and palmitoleic acid (16:1) become more prominent and oleic acid (18:1) and palmitic acid (16:0) less prominent as the adult ages. At about 40 days of adult age myristic acid (14:0) begins to decrease and oleic acid (18:1) to increase. Within 20 days of eclosion males and females contain different amounts of myristic acid (14:0), palmitic acid (16:0) and oleic acid (18:1).
