Abstract

In this article we investigate photo effect of vitamin D and foliate and the effect to the variation of skin colour.We use a UV/VIS spectrometer to record the absorption spectrum of foliate.Relating this to the synthesis of vitamin D and formation of melanin in the skin under UV radiation,we explain how all these factors contribute to skin colour change.Foliate degrades quickly when riboflavin is represented under UVB and blue light.The result indicates that human skin pigmentation may evolve as a protection of the UV sensitive vitamin folate in the blood and the balancing needs of folate protection and vitamin D production.

皮肤颜色的光效
本文研究了维生素D和叶酸的光效应及其对皮肤颜色变化的影响。我们用紫外/可见分光光度计记录了叶酸盐的吸收光谱。这与紫外线辐射下皮肤中维生素D的合成和黑色素的形成有关,我们解释了所有这些因素是如何导致皮肤颜色变化的。当核黄素被UVB和蓝光照射时,叶面迅速降解。该结果表明,人类皮肤色素沉着可能演变为对血液中紫外线敏感的维生素叶酸的保护,以及叶酸保护和维生素D生成的平衡需求。
