The uptake of alpha-tocopherol and vitamin K(1) by pea stem sections is described. Vitamin K(1) appears to be stable within the plant tissue and is found distributed in all particulate cell fractions following uptake. Only a small proportion of the tocopherol taken up is recoverable and the majority of the compound appears to undergo catabolism.The oxidation of tocopherols by a cell-free system is described. This system requires oxygen and appears to involve enzyme activity but does not appear to be linked with the action of lipoxidase.
描述了豌豆茎段对α-生育酚和维生素 K(1)的摄取。维生素 K(1)在植物组织内似乎是稳定的，并且在摄取后可在所有颗粒细胞部分中找到。只有一小部分被摄取的生育酚可回收，并且大部分化合物似乎经历了分解代谢。描述了无细胞体系中生育酚的氧化。该体系需要氧气，并且似乎涉及酶活性，但似乎与脂氧合酶的作用无关。
