胰島素是由胰島β細(xì)胞受內(nèi)源性或外源性物質(zhì)如葡萄糖、乳糖、核糖、精氨酸、胰高血糖素等的刺激而分泌的一種蛋白質(zhì)激素。胰島素是機(jī)體內(nèi)*降低血糖的激素,也是*同時(shí)促進(jìn)糖原、脂肪、蛋白質(zhì)合成的激素。
胰島素能促進(jìn)全身組織對(duì)葡萄糖的攝取和利用,并抑制糖原的分解和糖原異生,因此,胰島素有降低血糖的作用。胰島素分泌過(guò)多時(shí),血糖下降迅速,腦組織受影響zui大,可出現(xiàn)驚厥、昏迷,甚至引起胰島素休克。相反,胰島素分泌不足或胰島素受體缺乏常導(dǎo)致血糖升高;若超過(guò)腎糖閾,則糖從尿中排出,引起糖尿;同時(shí)由于血液成份中改變(含有過(guò)量的葡萄糖), 亦導(dǎo)致高血壓、冠心病和視網(wǎng)膜血管病等病變。胰島素降血糖是多方面作用的結(jié)果。
胰島素能促進(jìn)脂肪的合成與貯存,使血中游離脂肪酸減少,同時(shí)抑制脂肪的分解氧化。胰島素缺乏可造成脂肪代謝紊亂,脂肪貯存減少,分解加強(qiáng),血脂升高,久之可引起動(dòng)脈硬化,進(jìn)而導(dǎo)致心腦血管的嚴(yán)重疾患;與此同時(shí),由于脂肪分解加強(qiáng),生成大量酮體,出現(xiàn)酮癥酸中毒。
胰島素一方面促進(jìn)細(xì)胞對(duì)氨基酸的攝取和蛋白質(zhì)的合成,一方面抑制蛋白質(zhì)的分解,因而有利于生長(zhǎng),腺垂體生長(zhǎng)激素的促蛋白質(zhì)合成作用,必須有胰島素的存在才能表現(xiàn)出來(lái)。因此,對(duì)于生長(zhǎng)來(lái)說(shuō),胰島素也是*的激素之一。
