# Vitamin B12 – 10ml/vial (10mg/ml) (Research Use Only)

### Overview

Vitamin B12 (cobalamin) is an essential water-soluble vitamin and coenzyme that occupies a central position in cellular methyl-group metabolism, neurological function, and one-carbon biochemistry. As the cofactor for methionine synthase (homocysteine remethylation) and methylmalonyl-CoA mutase (propionate catabolism), B12 has been extensively studied in published research models spanning hematology, neurology, metabolic biochemistry, and aging biology. Portal to Wellness supplies pharmaceutical-grade B12 in a high-concentration injectable format for laboratory research applications.

### What It Is

This product provides cyanocobalamin at 10mg/mL concentration in a 10mL multi-dose vial, yielding 100mg total B12 content. Molecular formula: C₆₃H₈₈CoN₁₄O₁₄P (cyanocobalamin), MW ~1,355 Da. CAS number: 68-19-9. B12 contains cobalt at its core corrin ring and functions as the methyl and adenosyl group donor in two essential mammalian enzymatic reactions.

### Key Research Applications

- One-carbon metabolism and methionine cycle pathway research
- Homocysteine remethylation and methylation capacity studies
- Neurological myelin synthesis and axonal integrity research in deficiency models
- Methylmalonyl-CoA mutase activity and propionate metabolism studies
- B12 deficiency modeling and cognitive function marker research in rodent models
- DNA methylation pattern and epigenetic regulatory research
- Comparative bioavailability studies across B12 forms (cyano, methyl, adenosyl, hydroxo)
- Hematopoietic modeling and megaloblastic anemia mechanistic research
