應用

DL-亮氨酸是亮氨酸D-和L-对映体的一种外消旋混合物。DL-亮氨酸可用于与多种过渡金属形成苯并咪唑和嘧啶羟基偶氮染料。DL-亮氨酸可用于评估手性氨基酸分离技术。

DL-亮氨酸可用于以下应用：
  • 用作测量游离氨基酸的标准品
  • 用于氚亮氨酸摄取的过程
  • 用于溶液制备（各种有机物以不同的组合和浓度用于模拟复杂的表面张力效应，DL-亮氨酸是其中之一）。选择它的原因是它在大气气溶胶中的存在和冰的成核活性以及其表面活性剂的特性

Transfusion-associated graft-versus-host disease (TA-GVHD) is usually a fatal outcome of blood transfusion therapy, caused by viable leucocytes contained in the donor blood. Most cases of TA-GVHD occur when less than 4-d-old blood is transfused. We therefore examined the molecular changes

Nutritional energy support during extracorporeal membrane oxygenation (ECMO) should promote successful myocardial adaptation and eventual weaning from the ECMO circuit. Fatty acids (FAs) are a major myocardial energy source, and medium-chain FAs (MCFAs) are easily taken up by cell and

Sodium-coupled transporters are ubiquitous pumps that harness pre-existing sodium gradients to catalyse the thermodynamically unfavourable uptake of essential nutrients, neurotransmitters and inorganic ions across the lipid bilayer. Dysfunction of these integral membrane proteins has been implicated in glucose/galactose malabsorption, congenital
