简要介绍｜β-淀粉样蛋白（1-38）/β-Amyloid（1-38）｜的相关信息

β-淀粉样蛋白是AD脑中淀粉样蛋白沉积的主要成分。β-淀粉样肽有一个异质的C末端，大多数由aβ1-40组成，而次要产物是aβ1-42。通常还会产生其他次要的aβ肽，如β-淀粉状肽1-34、1-37、1-38和1-39，很少有报告量化了这些肽在大脑中的水平。

Beta-amyloid  is the main component of amyloid deposits in the AD brain. Beta-amyloid  peptides have a heterogeneous C-terminus with the majority composed  ofAβ1-40, while a minor product is Aβ 1-42. Additional minor Aβ peptides  are also normally produced, such as Beta-amyloid 1-34, 1-37, 1-38 and  1-39, and few reports have quantified the levels of these peptides in  the brain.
