Abstract:
Plant physiologists and biochemists are unraveling the transport mechanisms and biosynthetic pathways that determine each plant's unique phytonutrient composition so that crop plants can be modified to improve their nutrition quality. However, before this goal can be achieved, more information is needed on various plant and human phytonutrient-related processes, and some new technical capabilities are required. The current status of our knowledge base and recommendations for technical improvements and research priorities will be discussed.

Factors Affecting Drug Distribution: Physiological Barriers
The capillary endothelial barrier allows only smaller molecules below 600 Da (Daltons) to pass through. It also restricts drugs like heparin that are bound to blood components, limiting their movement within the bloodstream.
