β amyloid (18 28)

Intracerebroventricular administration of synthetic peptides Beta-amyloid (12-20), (12-28), and (18-28) causes amnesia in mice. These peptides have only amino acid residues VFF at position 18 to 20 in common, suggesting the amnestic effect of the triad.

β-Amyloid (1-28), a fragment of the β-Amyloid protein, is involved in metal binding.

β Amyloid(17-28) human 为β-淀粉样肽(Abeta)的一段核心片段，其结构受脂质诱导。本化合物能够促进β Amyloid40全长肽段的聚集，导致阿尔茨海默病(AD)中具毒性的聚集体形成。

β-Amyloid (12-28) (TFA)为β-淀粉样蛋白(β1-42)的肽片段，后者是由42个氨基酸组成，构成老年斑核心的关键蛋白。β-Amyloid (12-28) (TFA)展现出聚集性质，并可能对阿尔茨海默氏病研究具有潜在价值。

β-amyloid (12-28) TFA, a peptide fragment of β-amyloid protein (β1-42), is the major component of senile plaque cores. β-amyloid (12-28) has aggregation properties and the potential for Alzheimer’s disease research.

Amyloid β-peptide fragment; minimum section required to bind to brain proteins. Binds with high affinity to α7-nicotinic ACh receptors, and impairs memory retention following central administration in mice in vivo.

β Amyloid(28-35) human 是一种具有神经毒性的β-淀粉样肽，能够与神经元膜结合，影响其二级结构并加剧阿尔茨海默病的神经毒性。该肽段对酸性磷脂DPH表现出非均向性作用，从而增加脂质膜双层内部的流动性。该核心片段由脂质诱导形成。
