类维生素A的生理功能研究进展

Progress of Physiological Function on Retinoid

类维生素A是一类脂溶性物质,动物体内不能合成,必须从饲粮中摄取,属于动物必需营养物质。在调节和控制多种正常组织和上皮细胞的增殖分化、生长发育、形态发生、代谢、内环境的稳定平衡、暗视觉和生殖等方面具有广泛的生物学活性。其结构、代谢、受体以及一些生理功能作具有非常重要的意义,受到越来越广泛的关注及越来越深入的研究。

Retinoid is a kind of fat-soluble substance and essential nutrients, which can not be synthesized in animal body, and must be obtained from feed. Retinoid has a lot of biological activities including normal tissue and epithelial cell proliferation differeofia tion, growth and development, morphogenesis, metabolism, stable equilibrium of internal environment, scotopic vision and reproductive.
