Studies have been carried out in the presence of @entity897 , by utilizing a technique of platelet rapid filtration. Kinetic data suggest that @entity413 uptake across plasma membrane is the rate limiting step in its utilization. @entity897 is transported by facilitated diffusion. @entity413 is transferred at only 1/1200 of the rate of @entity413 . Transport system shows high affinity for substrate. Transport is inhibited by @entity2389 , @entity16802 and @entity8816 . @entity33264 does not affect @entity897 uptake. @entity13131 can have activating or inhibitory effect. @entity2469 is always activating. Insulin has no effect on rate transport. @entity413 , @entity10546 , non radioactive @entity897 and @entity3913 are strong competitors, whereas @entity3649 and @entity8691 compete weakly with @entity897 transport.
