Analysis of Insulin and Insulin-Like Growth Factor-I Receptors in Neural Tissues

A variety of biochemical and physiological studies in recent years have made it clear that the brain possesses specific receptors and puta- tive signal transduction pathways for insulin and the insulin-like growth factors (IGF-I and IGF

Assaying Tyrosine Phosphorylation of Insulin Receptor and Insulin Receptor Substrates

This chapter describes techniques to successfully detect tyrosine phosphorylation of the insulin receptor and insulin receptor substrate proteins. These assays demonstrate whether the insulin signaling pathway is activated at its earliest

胰岛素（insulin）

　　 胰腺中胰岛β细胞分泌的一种激素。 1922年由英国的班廷（ Banting）和贝斯特（ Best）所发现，为一种能降低血糖的物质。 1926年获得结晶的胰岛素。 1954年阐明胰岛素的氨基酸组成。到 60年代中期，已进行人工合成。我国于 1965年首次用化学方法合成了具有生物活性的结晶牛胰岛素；随后，查明了胰岛素的三级空间结构。胰岛素由 51个氨基酸组成 A、 B两条肽链， A链含 21个氨基酸， B链含 30个氨基酸，两条肽链之间借两个二硫键联结， A链
