概括
经典银河糖血症 (CG) 患者可以容忍适度的饮食银河糖增加. 血清N-甘氨酸分析为管理CG治疗干预提供了个性化的方法.
科学领域:
- 代谢障碍 代谢障碍 代谢障碍
- 代谢中的先天性错误
- 葡萄糖科学 (Glycoscience) 是一种科学.
背景情况:
- 经典的银河糖血症 (CG) 是一种罕见的代谢障碍,由银河糖-1-酸盐尿基转移酶缺乏引起.
- 虽然限制银河糖的饮食可以预防新生儿并发症,但长期问题如神经缺陷和生育问题仍然存在.
- 目前的治疗侧重于严格的饮食限制,但长期的结果仍然不够理想.
研究的目的:
- 调查成年CG患者饮食中的银河糖摄入量轻度至中度放松的影响.
- 为了将饮食中的银河糖摄入量与红细胞 (RBC) Gal-1-P水平和血清IgG N-甘氨酸样本相关联.
- 探索N-甘氨酸分析对个性化CG管理的潜力.
主要方法:
- 对31名爱尔兰成年CG患者的回顾性分析,分为三个饮食中摄入银河糖的组 (<200毫克/天,200-500毫克/天,501-1000毫克/天).

Glucose Transporters
27.9K
Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

Inborn Errors of Metabolism
967
Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...

Glucose Absorption Into the Small Intestine
36.7K
Complex carbohydrates consumed cannot be absorbed into the small intestine in their original form. First, they must be hydrolyzed to a monosaccharide form such as glucose or galactose. These monosaccharides are then transported across the intestinal membrane and into the blood via transcellular transport. The intestinal epithelial cells allow the movement of these monosaccharides with a defined 'entry' through membrane transporter proteins present on their apical membrane and...

Diabetes Mellitus: Type 2 and Gestational
5.3K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Overview of Carbohydrate Metabolism
4.0K
Carbohydrate metabolism is a fundamental biochemical process that ensures a constant supply of energy to living cells. The most important carbohydrate is glucose, which can be broken down via glycolysis to enter into the Krebs cycle and eventually lead to the production of ATP through oxidative phosphorylation.
Glucose transport into cells is facilitated by a family of transport proteins called GLUT (Glucose Transporters). GLUT4 is the primary glucose transporter for insulin-stimulated glucose...

Hypoglycemia and Glucagon
1.1K
Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...
