應用

半乳糖被应用于:
  • 作为半乳糖基转移酶标记缓冲液的组分。[1]
  • 作为MRS肉汤中嗜热乳酸菌生长的补充物[2]
  • 诱导解耦蛋白(UCP)在酵母转化子中的表达[3]

生化/生理作用

半乳糖是一种简单的单糖,是能量来源和糖脂和糖蛋白的基本成分。半乳糖通过构成Leloir通路的酶将其转化为葡萄糖,从而促进能量代谢。编码这些蛋白质的基因缺陷导致了代谢性半乳糖血症。

    The ability to ferment galactose is a major characteristic which can be used to differentiate Lactobacillus helveticus (galactose positive) from Lactobacillus lactis and Lactobacillus bulgaricus (galactose negative). In milk cultures, galactose-positive strains produced d- and l-lactic acid with little galactose

    The uncoupling protein is one of a family of mitochondrial transport proteins involved in energy metabolism. It dissipates oxidative energy to generate heat, either by catalyzing proton transport directly or by catalyzing fatty acid anion transport, thus enabling fatty acids

    Gut dysbiosis and oxidative stress may trigger senile osteoporosis. Fructus Ligustri Lucidi (FLL) has bone-preserving properties and affects the intestinal microecology. However, the mechanism of the anti-osteoporotic effect of FLL and its link to the gut microbiota remains to be

    Metabolic flexibility is an essential characteristic of eukaryotic cells in order to adapt to physiological and environmental changes. Especially in mammalian cells, the metabolic switch from mitochondrial respiration to aerobic glycolysis provides flexibility to sustain cellular energy in pathophysiological conditions.

    Many tumors display alterations in the biosynthetic pathways of glycosylation, resulting in increased expression of specific tumor-associated glycan structures. Expression of these altered glycan structures is associated with metastasis and poor prognosis. Antigen presenting cells can recognize tumor-associated glycan structures
