General description
D-半乳糖是葡萄糖的 C-4 外聚体,是一种关键的哺乳动物单糖,广泛存在于血液、牛奶、神经节苷脂以及 N 和 O 链聚糖中。它普遍存在于植物和动物中,并作为多种多糖的组成部分,包括半乳甘露聚糖、卡拉胶、琼脂(L-半乳糖)、半纤维素和半乳多糖。作为一种醛己糖,它是糖脂和糖蛋白的能量来源和关键元素。D-半乳糖经过酶促转化为 D-葡萄糖进行代谢或多糖储存,代表葡萄糖的 C-4 表聚体。
此外,半乳糖是双糖乳糖的基本成分,通过 β-半乳糖苷酶水解释放,在细菌的生存和毒力中起着至关重要的作用。在大肠杆菌中,半乳糖通过 Leloir 途径起效,其中 β-d-半乳糖作为碳源,β-d-半乳糖诱导 UDP-半乳糖合成以实现生物合成糖基化。半乳糖可用于研究代谢紊乱,如半乳糖血症,并作为参与半乳糖分解代谢的酶的底物,使其成为半乳糖转移酶标记缓冲液的重要成分和 MRS 肉汤中促进嗜热乳酸菌生长的补充物。

Application
D-(+)-半乳糖已用于:
- 用作SGal 培养基补充剂培养酵母菌株,以检查不同 SSA 热休克蛋白 (Hsp70) 亚型在 Hsp90 伴侣功能中的作用
- 用作Biolog (MT2) 微孔板测定中的碳源,测试分离物利用碳底物的能力
- 诱导酵母中膜蛋白-绿色荧光蛋白 (GFP) 融合表达
D-半乳糖是一种能量来源和代谢物,在细胞生物学、代谢组学和生物化学研究中有广泛的应用。
Biochem/physiol Actions
D-半乳糖代谢导致形成活性氧 (ROS) ,并导致氧化压力和肝细胞损伤。
半乳糖是一种简单的单糖,可作为能量来源,也是糖脂和糖蛋白的必需成分。半乳糖被Leloir途径的酶转化为葡萄糖,从而能够促进能量代谢。缺乏编码这些蛋白质的基因,将导致代谢功能紊乱疾病半乳糖血症。
Features and Benefits
- 非常适合代谢组学、生物学和生化研究
- 用途广泛,适用于各种实验室和研究应用。

Several plant diterpenes have important biological properties. Among them, forskolin is a complex labdane-type diterpene whose biological activity stems from its ability to activate adenylyl cyclase and to elevate intracellular cAMP levels. As such, it is used in the control

Glycosylation of biopharmaceuticals can mediate cell specific delivery by targeting carbohydrate receptors. Additionally, glycosylation can improve the physico-chemical (drug-like) properties of peptide based drug candidates. The main purpose of this study was to examine if glycosylation of the peptide enkephalin

It has been previously shown that the long-term inhibition of milking-induced prolactin (PRL) release by quinagolide (QN), a dopamine agonist, reduces milk yield in dairy cows. To further demonstrate that PRL is galactopoietic in cows, we performed a short-term experiment
