Vitamin B4 CAS No. 73-24-5

Product Description

Vitamin B4, also known as adenine, is a purine derivative that was once categorized as a B vitamin but is no longer considered a true vitamin. Adenine is a fundamental component of DNA and RNA, serving as one of the four nucleobases essential for carrying and expressing genetic information. It is also a key part of adenosine triphosphate (ATP), the primary energy carrier in cells, and is involved in coenzymes like NAD and FAD, which are crucial for cellular respiration and metabolism. Adenine can be found naturally in various foods, including meat, fish, whole grains, legumes, and mushrooms, but it is also synthesized by the human body from other compounds. Unlike essential vitamins such as B1 and B12, which must be obtained through diet, adenine is produced endogenously, making dietary deficiency rare. While it is no longer classified as a vitamin in modern science, adenine remains vital for overall health, playing a significant role in energy production, genetic information, and cellular functions.

Product Use & Characteristics

Chemical Identity:

• Molecular Formula: C₅H₅N₅

• Molecular Weight: 135.13 g/mol

• IUPAC Name: 7H-purin-6-amine

• Other Names: Adenine, 6-Aminopurine, 1H-Purin-6-amine, 7H-Purin-6-amine

Structure:

• A purine base with an amino group at the 6-position.

Classification Status:

• Historically referred to as Vitamin B4, but no longer classified as a vitamin because it can be synthesized by the human body and is not an essential nutrient.

Historical Context:

• In the early days of vitamin research, adenine was temporarily labeled as a vitamin. As knowledge advanced, it was reclassified and is no longer included in the official list of vitamins.

Synthesis Methods:

• Adenine is synthesized by the human body from other compounds.

• Naturally found in meat, fish, whole grains, legumes, and mushrooms.

Uses

Biological Role:

• Energy Production: Essential for converting energy from food into a usable form (ATP).

• Protein Synthesis: Involved in the process of building and repairing proteins.

• Genetic Information: Fundamental component of DNA and RNA, essential for carrying and expressing genetic information.

• Cellular Processes: Participates in various biochemical reactions within cells, including metabolism and energy transfer.

• Immune System Support: May contribute to a healthy immune system by supporting cell formation and tissue development.

• Other Roles: May help maintain healthy blood sugar levels and protect against cell damage.

Medical and Research Uses:

• Used in immunosuppressive drugs (e.g., azathioprine).

• Studied in genetics and biochemistry due to its role in nucleic acids.

Other Information

No Current Recommended Daily Allowance (RDA):

• Since adenine is not a vitamin and the body can produce it, there is no RDA or specific dietary recommendation for adenine.

Misconceptions:

• Some older literature lists adenine as "Vitamin B4," but modern science does not classify it as a vitamin. True B vitamins (like B1, B2, B3, etc.) must be obtained from food, whereas adenine is synthesized by the body.
