Why Vitamin B12 is not absorbed in the body?

Can vitamin B12 cause elevated liver enzymes?
Our results demonstrate a substantial positive relationship between vitamin B12 and hepatic enzyme serum levels. This correlation may be interpreted as meaning that, with increasing hepatocellular damage, as indicated by elevated hepatic enzymes, serum vitamin B12 also tends to be higher.
What is the function of B12 cobalamin?
