By what name is Vitamin B1 known which is essential for glucose metabolism and healthy nerve, muscle and heart function?
Riboflavin
Niacin
Pantothenic acid
Thiamin
Thiamin
Vitamin B1, also known as Thiamin, is a water-soluble B-complex vitamin essential for the conversion of carbohydrates into energy. It acts as a vital coenzyme in metabolic processes, supporting nerve, muscle, and cardiovascular health.

Think of Thiamin as the 'spark plug' for a car engine; even if you have fuel (glucose), the engine won't start or run smoothly without the spark plug to initiate the energy conversion process.
B1 is 'T-1' (Thiamin is #1).
TPP+C3тАЛH4тАЛO3тАЛтЖТAcetyl-CoA+CO2тАЛ тАФ the decarboxylation reaction mediated by Thiamin pyrophosphate
Thiamin is converted into its active form, Thiamin pyrophosphate (TPP), in the body. TPP functions as a coenzyme for key enzymes such as pyruvate dehydrogenase, which catalyzes the oxidative decarboxylation of pyruvate to acetyl-CoA, a crucial step in the Krebs cycle (C6тАЛH12тАЛO6тАЛтЖТ2C3тАЛH4тАЛO3тАЛ+4H+2ATP is the glycolysis precursor to this cycle). This mechanism ensures efficient cellular respiration and energy production.
Thiamin is water-soluble, meaning it is not stored in the body and must be replenished daily.
A deficiency of Thiamin leads to a disease called Beriberi, characterized by nerve damage and heart failure.
Rich food sources include whole grains, legumes, pork, and enriched cereals.
Supports healthy brain function and cognitive development.
Essential for the production of neurotransmitters like acetylcholine.
Highly sensitive to heat and alkaline pH, which can destroy the vitamin during cooking.
Used as a dietary supplement for alcohol-dependent individuals to prevent Wernicke-Korsakoff syndrome.
Used in food fortification programs to prevent deficiency-related neurological disorders.
Riboflavin (Option A) is Vitamin B2.
Niacin (Option B) is Vitamin B3.
Pantothenic acid (Option C) is Vitamin B5.
The recommended daily intake for adults is typically 1.1 to 1.2 mg per day.
D is correct тАФ Thiamin is the biological name for Vitamin B1, a coenzyme critical for carbohydrate metabolism.
In competitive exams, remember that B-vitamins are water-soluble; they are often leached into cooking water, which is why 'boiling' vegetables often reduces their nutritional content.
