| Abstract: | Variations in ascorbic acid content of the ovary, somatic tissues and the whole female body were studied during ovarian development and the molting cycle of Palaemon serratus. The conclusions are incomplete, due to insufficient data on the role of ascorbic acid in the physiology and metabolism of animals, and especially crustaceans. However, some results indicate that Vitamin C is accumulated in the female as the gonad index increases. Ascorbic acid is concentrated preferentially in the ovarian tissue. Some hypotheses are put forward relating to the role of ascorbic acid in the biosynthesis of chitin, steroid hormones, and in ovarian maturation. |
