一般描述
乳糖是一种由一个半乳糖和一个葡萄糖分子缩合而成的物质。乳糖是大多数种类牛奶中的主要糖，通常含量在2-8%之间。乳糖酶将乳糖水解成其组成单糖。在新生儿中，通过乳糖酶作用释放的葡萄糖是主要的能量来源。
应用
乳糖检测试剂盒已用于测量牛奶中的乳糖含量。
适用性
适用于直接测量各种生物样本（血清、血浆、其他体液、食物、生长培养基等）中的乳糖水平。
原理
在该测定中，乳糖浓度通过酶法测定，其中乳糖转化为半乳糖和葡萄糖。半乳糖随后被氧化，产生比色（570 nm）/荧光（λex = 535 nm/λem = 587 nm）产物，与最初存在的乳糖成比例。该试剂盒适用于各种生物样本，荧光测定法的线性检测范围为0.2-1.0 nmole乳糖，比色测定法的线性检测范围为2-10 nmole乳糖。

Breastfeeding confers robust benefits to offspring development in terms of growth, immunity, and neurophysiology. Similarly, improving environmental complexity, i.e., environmental enrichment (EE), contributes developmental advantages to both humans and laboratory animal models. However, the impact of environmental context on maternal

Obesity is a prevailing problem across the globe. Women who are obese have difficulty initiating and sustaining lactation. However, the impact of genetics and diet on breastfeeding outcomes is understudied. Here we explore the effect of diet and genotype on

Water scarcity is threatening food security and business growth in the United States. In the dairy sector, most of the water is used in cleaning applications; therefore, any attempt to support water conservation in these processes will have a considerable

High-fat diet (HFD) during lactation alters milk composition and is associated with development of metabolic diseases in the offspring. We hypothesized that HFD affects milk microRNA (miRNA) and mRNA content, which potentially impact offspring development. Our objective was to determine
