U.S.-Brazil Planning Visit to the National Institute for Amazonian Research, INPA, Manaus, Brazil

9514199 Fracalossi这笔美国-巴西规划赠款将支持国家动物园和史密森学会的Debora Fracalossi前往巴西马瑙斯，与国家亚马逊研究所的Vera M.Fonseca de Almeida e Val建立合作关系。最终目标将是对亚马逊河鱼中的L-古龙内酯氧化酶活性进行比较研究。这将伴随着这种活动与饮食之间的相关性，包括对鱼类消耗的水果和种子中维生素C水平的研究。更广泛的目标是更深入地了解脊椎动物中维生素C的生物合成。国家动物园和INPA之间建立合作是非常有希望的，对双方都有好处。这项研究具有内在的意义，它扩展了我们对生理过程的了解，并有可能应用于营养学。***

9514199 Fracalossi This U.S.-Brazil planning grant will support a trip by Debora Fracalossi of the National Zoo and Smithsonian Institution to Manaus, Brazil to establish a collaboration with Vera M. Fonseca de Almeida e Val of the National Institute of Amazonian Research (INPA). The eventual objective will be to perform a comparative study of the L-gulonolactone oxidase activity in Amazonian fish. This is to be accompanied by correlation between such activity and diet, including studies of the vitamin C levels in fruits and seeds consumed by fish. The broader objective is a deeper understanding of the biosynthesis of vitamin C in vertebrates The establishment of cooperation between the National Zoo and INPA is very promising, with benefits to both sides. The research is of intrinsic interest, extending our knowledge of physiological processes, and of potential application to nutrition. ***
