Vitamin D3 β-D-glucuronide-d7

Vitamins are a category of trace organic compounds essential for maintaining normal physiological functions in living organisms. They are classified into fat-soluble and water-soluble vitamins. Fat-soluble vitamins play a role in maintaining vision, bone health, reproductive functions, and blood coagulation. Water-soluble vitamins are involved in energy metabolism, nervous system function, and cellular repair processes. Most vitamins cannot be synthesized by the organism and must be obtained through diet. In recent years, vitamins and their derivatives have become increasingly important in the field of drug development due to their extensive physiological activities. Additionally, vitamins and their derivatives can be used to construct research platforms for vitamin metabolism, which helps to delve into the metabolic pathways and dynamic changes of vitamins within the body and aids in identifying new biomarkers for certain diseases.

MCE included 135 vitamins and their derivatives, including Vitamin A, Vitamin B, Vitamin D, etc., which is a good tool for studying vitamin metabolism.

Human metabolism is an integral part of cellular function that reflects individual differences in health, disease, diet, and lifestyle. Many health conditions such as obesity, diabetes, hypertension, heart disease, and cancer are associated with abnormal metabolic states. In the pathological state of the human body, metabolic pathways are significantly altered, resulting in aberrant levels of intermediates or end-products that can be viewed as potential diagnostic biomarkers or even therapeutic targets. Therefore, detection, identification and quantification of human metabolites are very important for drug metabolism research in drug development.

MCE offers a unique collection of 6,712 human metabolites, including endogenous metabolites and exogenous metabolites, covering multiple structure types, such as lipids, amino acids, nucleic acids, carbohydrates, organic acids, biogenic amines, vitamins,. MCE Human Metabolites Library is a helpful tool for studying the relationship between diseases and metabolism.

Dietary supplement, also known as nutritional supplement or food supplement, include dietary components such as vitamins, minerals, and amino acids. The unique value of dietary supplement is particularly significant in the post-pandemic era. Compared to traditional medication, dietary supplement is often more readily accepted by the public due to their higher safety profile and the natural origin. By orally supplementing essential nutrients and bioactive substances, dietary supplement can help to enhance the body's health level and reduce the risk of diseases. For certain chronic conditions, proper dietary supplement can also serve as a powerful adjunct to conventional medical treatment, enhancing the effectiveness of medication.

Heterocyclic compounds are cyclic organic compounds which contain at least one hetero atom, the most common heteroatoms are nitrogen, oxygen ,and sulfur. Heterocycles are common in biology, featuring a wide range of structures from enzyme co-factors to amino acids and proteins. On the one hand, heterocycles are common structural units in approved drugs and in medicinal chemistry targets in the drug discovery process. In addition, heterocycles have been found as a key structure in medical chemistry and also they are frequently found in large percent of biomolecules such as vitamins, natural products ,and biologically active compounds including antifungal, anti-inflammatory, antibacterial, antioxidant, antiallergic, anti-HIV, antidiabetic, anticancer activity.

MCE offers a unique collection of 6,484 heterocyclic compounds which can be used for drug discovery for high throughput screening (HTS) and high content screening (HCS). MCE heterocyclic compound library is critical for drug discovery and development.

Hormones are a class of biologically active substances secreted by endocrine gland cells, which are transported through the circulatory system to various parts of the body, and precisely act on specific target organs or cells, playing a crucial role in regulating the growth, development, metabolism, and reproduction of organisms. The mechanisms of hormone action are diverse and complex. Some hormones (such as corticosteroids, vitamin D, and thyroid hormones) can enter the cell interior and interact with receptors in the nucleus, thereby regulating gene expression and affecting cell function. Other hormones (such as growth hormone and thyrotropin-releasing hormone) bind directly to receptors on the cell surface, exerting their effects by regulating enzyme activity or influencing the state of ion channels. Additionally, hormones play a key role in the study of endocrine and metabolic diseases, and are closely related to the development of diseases such as diabetes and thyroid diseases.

MCE has included 86 human hormone compounds, which is of great significance for the study of human metabolic pathways, and can also be used to build a metabonomics database.

MCE MEM Vitamin Solution (100×) contains eight vitamins, including choline chloride, D-calcium pantothenate, folic acid, nicotinamide, pyridoxal hydrochloride, riboflavin, thiamine hydrochloride, and inositol. It can be used as a serum-free supplement for cell culture media to enhance cell viability and promote cell growth.

RPMI 1640 contains glutathione and high concentration of vitamins, also contains biotin, vitamin B12, 4-Aminobenzoic acid (PABA) not found in MEM and DMEM, as well as high concentration of inositol and choline chloride. The 500 mL is defined as the base specification. All larger sizes correspond to incremental volumes of this base.

This product is serum-free and vitamin A-free.It is a customized variant of the standard Bi-27 formulation with vitamin A removed as a supplement for neuronal cell culture to support the low- or high-density growth and short- or long-term viability of embryonic. This product is formulated with water-for-injection. The 10 mL is defined as the base specification. All larger sizes correspond to incremental volumes of this base.

MCE Bi-27 Serum-free Supplement (50×), Vitamin A-Free can be used to support the low- or high-density growth and short- or long-term viability of embryonic. This product is formulated with basal culture medium. The 10 mL is defined as the base specification. All larger sizes correspond to incremental volumes of this base.

MCE Bi-27 Serum-free Supplement (50×), Antioxidant-Free is a customized neuronal culture supplement developed by removing antioxidants components (such as vitamins, superoxide dismutase, catalase, etc.) from the standard Bi-27 formulation. It is specifically designed for investigating the roles of reactive oxygen species (ROS) in aging, cytotoxicity, apoptosis, and chronic neurological diseases. This formulation provides a stable culture environment for mechanistic studies without the interference of exogenous antioxidants.

Minimum Essential Medium (MEM), also known as Minimal Essential Medium, was developed by Harry Eagle based on Eagle’s Basal Medium (BME). It is a basic cell culture medium with a simple formulation and broad applicability, and is one of the most commonly used media in animal cell culture. MEM contains only 12 essential amino acids, L-glutamine, and 8 vitamins. It is primarily used for the culture of adherent cells. With appropriate formulation modifications, it can also be used for other types of cell culture.
