What is the Origin of Vitamin B12 Deficiency?

"Vitamin" is a coined term from the Latin vita (life) and amine (referring to the chemical class). "Deficiency" stems from the Latin deficere, meaning "to fail or lack." The term describes a lack of this life-essential micronutrient, a condition recognized clinically in the early 20th century.

What is the Mechanism of Vitamin B12 Deficiency?

The most common cause is impaired absorption due to a lack of intrinsic factor, a protein required for B12 uptake in the small intestine, a condition known as pernicious anemia. Without sufficient B12, two critical enzymatic reactions are impaired: the conversion of methylmalonyl-CoA to succinyl-CoA and the conversion of homocysteine to methionine. The resulting accumulation of MMA and homocysteine is toxic to the nervous system and disrupts the formation of healthy red blood cells, leading to clinical manifestations.

Vitamin B12 Deficiency

Meaning

A clinical condition characterized by insufficient levels of cobalamin (Vitamin B12), an essential micronutrient required for DNA synthesis, red blood cell formation, and the maintenance of the central and peripheral nervous systems. This deficiency often results in megaloblastic anemia and can lead to severe, irreversible neurological symptoms if left untreated. Clinical diagnosis requires measuring serum B12 and often methylmalonic acid (MMA) and homocysteine levels, which are functional markers of its metabolic impact and severity.
