Enrichment of fish eggs with ascorbic acid
Success in aquaculture depends on the mass production and quality of juveniles. However, many fish species suffered high losses during the early stages of development. Therefore, in order to decrease mortality, produce a large number of healthy larvae is a fundamental issue. On the other hand, one of the micronutrients that can be effective in larvae health is ascorbic acid. During the embryoni...
متن کاملAscorbic acid - Vitamin C Healthy, powerful and interfering Ascorbic acid and its interference with urinalysis results of urine test strips
Since the discovery of vitamin C more than 70 years ago scientists have been debating its general impact on human health und its dietary requirement. The possible prophylactic and therapeutic potential in chronic diseases results in sustained and even public interest. Ingesting huge amounts of vitamin C is now common and this means that large quantities are excreted in the urine. Does vitamin C...

متن کاملKINETIC DETERMINATION OF ASCORBIC ACID a WITH SPECTROPHOTOMETRIC DETECTION
A simple and rapid method has been developed for the determination of ascorbic acid in fruit and pharmaceutical products. The method is based on the measurement of the reaction rate between ammonium molybdate and ascorbic acid in acidic media. The reaction was monitored spectrophotometrically at 800 nm by fixed-time and variable-time methods. The calibration graph was linear in the range of...
متن کاملThe chemical identification of ascorbic acid in urine.
DURING the past 3 years several methods have been proposed, and widely used, for the estimation of ascorbic acid in urine. They all depend on the reducing properties of ascorbic acid and are all non-specific. By careful limitation of conditions it is possible, with these methods, to exclude interference by a number of substances known to be present in urine and to reduce the reagents employed. ...
