TDS FOR VITAMINS
 
 
 
TDS OF Vitamin B12
 
Product Name:       Vitamin B12
CAS Number:       V2876
MDL:              MFCD00151092
Formula::           C63H88CoN14O14P
Formula Weight:     1,355.37 g/mol
Storage Temperature: 2 - 8 °C
 
 
 
 
Vitamin B12 was discovered from its relationship to the disease pernicious anemia, which is an autoimmune disease in which parietal cells of the stomach responsible for secreting intrinsic factor are destroyed. Intrinsic factor is crucial for the normal absorption of B12, so a lack of intrinsic factor, as seen in pernicious anemia, causes a vitamin B12 deficiency. Many other subtler kinds of vitamin B12 deficiency and their biochemical effects have since been elucidated

substances that damage DNA. The build-up of free
radicals over time may contribute to the aging process
and the development of health conditions such as
cancer, heart disease, and arthritis.
