喝完「无糖饮料」还想吃甜食?原来人们对糖的渴望,无法被甜味剂替代,答案都在肠道里!
Neuropod 细胞(图片来源:Borhóquez Lab, Duke University) 虽然感觉甜味取决于舌头,但研究表明十二指肠也可以将糖分与甜味剂区分开来。蔗糖是 D-葡萄糖和 D-果糖组成的二糖。与 D-果糖或甜味剂三氯蔗糖不同,D-葡萄糖在十二指肠腔时会产生强烈的偏好。事实上,先前接触过 D-葡萄糖的动物会在几分钟内识别出进入肠道的糖分。而当绕过小肠时,这种识别 D-葡萄糖的能力就会消失,这表明十二指肠上皮是「糖传感器」细胞所在的地方。但到目前为止,由于缺乏以时间和空间精度控制肠道感觉
Cell Metabo: 另辟蹊径!武汉大学李红良等团队合作发现 2 型糖尿病治疗新靶点
2018 年 the Lancet 研究统计显示,空腹高血糖是中国人群寿命的第三大危险因素 (1)。人体 90% 的内源性葡萄糖来自肝葡萄糖生成(hepatic glucose production, HGP),是维持体内糖稳态的重要组成部分 (2)。 图片来源:the Lancet 空腹 HGP 增加是 T2D (2 型糖尿病)的标志,HGP 率高于正常生理水平,表现为肝胰岛素抵抗,葡萄糖代谢能力下降,是患者空腹高血糖的一个重要原因。现有的降糖药物对 T2D 患者有疗效,但仍有局限性。令人
蔗糖酶 sucrase 将蔗糖水解成 D-果糖和 D-葡萄糖的β-D-果糖苷酶的一种,又称为转化酶(invertase)或蔗糖酶(saccharase) EC 3.2.1.26。除广泛分布于微生物、植物外,类似的活性也在动物的消化液中发现,从链孢霉提纯获得的酶除作用蔗糖外,还可作用具有β-呋喃果糖苷键的物质。例如棉子糖、水苏糖等的寡糖,尤其也能同样地作用具有作为糖苷配基的甲基等的烷基、苯基等丙烯基的配糖体。一般微生物的蔗糖酶也催化从蔗糖将β-果糖苷基转移到其他糖、醇、酚上的反应
