Unlike most animals, most bats cannot synthesize vitamin C endogenously. Consequently, this vitamin must be obtained from the diet. Among the bat species, there are several food groups, such as frugivorous, nectarivorous, insectivorous, and hematophagous. In this work, we measured and compared vitamin C levels in different organs of four species of bats, all collected in southern Brazil. When analyzing and comparing the levels of vitamin C in the four bat species, (regardless of the organ), no significant differences were observed. However, when analyzing and comparing the levels of vitamin C in the four organs (regardless of the species), significant differences were observed, with the highest concentrations in the heart, followed by the liver and brain, while the lowest concentration was measured in the kidneys. Additional differences in the levels of Vitamin C were only observed when each organ was analyzed according to the species/diet. These results indicate a high degree of metabolic homeostasis in bats despite the marked difference in the type of diet.
与大多数动物不同，大多数蝙蝠无法内源性合成维生素C。因此，这种维生素必须从饮食中获取。在蝙蝠种类中，有几种食物类型，如食果性、食蜜性、食虫性和吸血性。在这项研究中，我们测量并比较了在巴西南部采集的四种蝙蝠不同器官中的维生素C水平。在分析和比较这四种蝙蝠的维生素C水平时（无论器官如何），未观察到显著差异。然而，在分析和比较这四个器官中的维生素C水平时（无论物种如何），观察到了显著差异，心脏中的浓度最高，其次是肝脏和大脑，而肾脏中的浓度最低。只有在根据物种/饮食对每个器官进行分析时，才观察到维生素C水平的其他差异。这些结果表明，尽管饮食类型存在显著差异，但蝙蝠仍具有高度的代谢稳态。
