Exploring the Impact of Cigarette Smoke Extracts on Vitamin B: Insights into the Transformation of Methylcobalamin and Hydroxycobalamin to Cyanocobalamin through Evaluation.

Vitamin B (cobalamin) is a water-soluble molecule required for the proper functioning of metabolism, blood and DNA synthesis, and neurological development. Vitamin B exists in several forms: methylcobalamin (MeCbl), adenosylcobalamin (AdoCbl), hydroxycobalamin (OHCbl), and cyanocobalamin (CNCbl). This study aimed to evaluate the effect of cigarette smoke on the chemical structure of methylcobalamin and hydroxycobalamin forms of vitamin B.
