Deficiency of which vitamin in the human diet leads to the nutritional disorder known as beriberi, characterized by neurological impairments and cardiovascular weakness?

💡 Solution & Explanation

Vitamin B one, also known as thiamine, is a water-soluble vitamin essential for carbohydrate metabolism and nerve function; its deficiency causes beriberi. Scurvy results from vitamin C deficiency, rickets is caused by vitamin D deficiency, and night blindness stems from vitamin A deficiency. Thiamine pyrophosphate acts as a crucial coenzyme in enzymatic decarboxylation reactions during cellular metabolism.
