視黃基

Developing prospect of the new wave-absorbing materials (nanometer agents, conducting polymer and retinyl schiff base) is also discussed. 展望了納米吸收劑、導(dǎo)電高分子、視黃基席夫堿等新型微波吸收劑的發(fā)展前景。

But in winter while the temperature was lower, they were mostly in deposited forms, so retinyl palmitat was at higher level than that in summer. 而冬季外界溫度較低，肝臟內(nèi)維生素主要以其儲存形式存在，表現(xiàn)出軟脂酸視黃酯含量高。

Try to avoid retinol, retinyl palmitate and retinyl acetate, which may increase the risk of hip fracture and certain birth defects when taken at levels exceeding 10,000 IUs. 實際上，有越來越多的證據(jù)表明，過量的攝取某種微量營養(yǎng)素會對人體有害。
