Alpha-Amylase CAS:9000-90-2 Manufacturer Price
Alpha-amylase is an enzyme that breaks down complex carbohydrates into smaller sugar molecules. It is produced in the pancreas and saliva glands and plays a crucial role in the digestion of starch, glycogen, and other polysaccharides. Alpha-amylase works by hydrolyzing the internal bonds within the carbohydrate chains, resulting in the release of glucose and maltose. This enzyme is widely used in various industries, such as food production and brewing, to facilitate the degradation of starch and improve the texture and digestibility of food products.

Streptomycin sulfate CAS:3810-74-0 Manufacturer Price
Streptomycin sulfate is an antibiotic medication that is primarily used to treat bacterial infections caused by susceptible strains of bacteria. It is part of a class of antibiotics called aminoglycosides. Streptomycin sulfate works by inhibiting the protein synthesis process in bacteria, which ultimately leads to their death.
Streptomycin sulfate is commonly used to treat infections caused by Mycobacterium tuberculosis, the bacterium responsible for tuberculosis (TB). It is also effective against some other Gram-negative bacteria, such as Escherichia coli and Salmonella species. However, it is not effective against Gram-positive bacteria.
This medication is typically administered by injection or intravenously, as its oral bioavailability is low. It is commonly used in combination with other antibiotics for the treatment of tuberculosis to prevent the development of drug resistance.

Acetyl coenzyme A sodium salt CAS:102029-73-2
Acetyl coenzyme A (acetyl-CoA) sodium salt is a synthetic derivative of acetyl-CoA. It is typically used in laboratory research and biochemical studies.
The main application of acetyl-CoA sodium salt is in cellular metabolism studies, particularly in investigating the role of acetyl-CoA in various metabolic pathways. Acetyl-CoA serves as a precursor for the synthesis of fatty acids, cholesterol, and ketone bodies, as well as playing a critical role in energy production through the citric acid cycle (also known as the Krebs cycle).
Additionally, acetyl-CoA is involved in the acetylation of proteins, DNA, and histones, which can affect gene expression and chromatin remodeling. Therefore, acetyl-CoA sodium salt can be used in studies focusing on these epigenetic modifications and their impact on cell function.

Rapamycin from Streptomyces hygroscopicus CAS:53123-88-9
Rapamycin is a naturally occurring compound isolated from the bacterium Streptomyces hygroscopicus. It has a wide range of biological activities and is primarily known for its immunosuppressive and anti-cancer properties.
Originally discovered as an antifungal agent, rapamycin has since been found to possess potent immunosuppressive properties, making it valuable in organ transplantation to prevent rejection. It does this by inhibiting the activation and proliferation of T-cells, a key component of the immune response.
Additionally, rapamycin has shown promising results in the treatment of various cancers. It works by inhibiting a protein called mTOR (mammalian target of rapamycin), which plays a critical role in cell growth and division. By blocking mTOR, rapamycin helps to control the unregulated growth of cancer cells.
