Thiamine, also known as vitamin B1, is a water-soluble vitamin that plays a crucial role in the body's ability to convert carbohydrates into energy. It is essential for the proper functioning of the nervous system, muscles, and heart.
Thiamine deficiency can lead to a condition known as beriberi, which is characterized by symptoms such as fatigue, weakness, nerve damage, and heart problems. Severe thiamine deficiency can also lead to a condition called Wernicke-Korsakoff syndrome, which is characterized by confusion, memory loss, and coordination problems.
Thiamine is found in a variety of foods, including whole grains, nuts, seeds, pork, and legumes. It is also commonly added to fortified foods such as breakfast cereals and bread.
Supplementation with thiamine is generally safe and well-tolerated, but it is important to consult with a healthcare provider before starting any new supplement regimen. Thiamine deficiency is rare in developed countries, but certain populations, such as alcoholics and individuals with certain medical conditions, may be at higher risk.
Overall, thiamine is an essential nutrient that plays a critical role in the body's overall health and well-being.

Thiamine (Vitamin B1)
Definition:
Thiamine is a water-soluble vitamin that is essential for human health. It plays a crucial role in carbohydrate metabolism and nerve function.
Structure:
Thiamine is a pyrimidine-thiazole compound. It consists of a thiazole ring fused to a pyrimidine ring.
Forms:
Thiamine occurs in two main forms:
- Thiamine monophosphate (TMP): The biologically active form found in tissues and cells.
- Thiamine pyrophosphate (TPP): The coenzyme form involved in most metabolic reactions.
Dietary Sources:
Thiamine is found in a wide variety of foods, including:
- Whole grains (brown rice, quinoa)
- Legumes (beans, lentils)
- Nuts (almonds, peanuts)
- Seeds (sunflower seeds, chia seeds)
- Meat (beef, pork)
- Dairy (milk, cheese)
- Fortified foods (cereals, bread)
Functions:
Thiamine is involved in numerous metabolic reactions, primarily related to carbohydrate metabolism:
- Glycolysis: Breaks down glucose into pyruvate, releasing energy.
- Pentose phosphate pathway: Generates ribose-5-phosphate for nucleotide synthesis.
- Citric acid cycle (Krebs cycle): Oxidizes acetyl-CoA to produce energy and CO2.
- Neurological function: Supports the health of nerves and the central nervous system.
Deficiency:
Thiamine deficiency, known as beriberi, can occur due to insufficient intake or absorption of vitamin B1. Symptoms include:
- Dry beriberi: Muscle weakness and fatigue
- Wet beriberi: Heart failure and edema
- Infantile beriberi: Rapid heart rate, poor feeding, and irritability
Recommended Daily Intake (RDI):
The recommended daily intake of thiamine varies depending on age, sex, and physiological status. Generally, adults need around 1.2-1.5 mg/day.
Absorption and Metabolism:
Thiamine is absorbed in the small intestine. It is then transported to the liver for storage and phosphorylation to TMP. TMP is converted to TPP, which is the active coenzyme form required for metabolic reactions.
Toxicity:
Thiamine toxicity is rare, but excessive intake can lead to allergic reactions, nausea, and vomiting.
Conclusion:
Thiamine is an essential vitamin that plays a vital role in carbohydrate metabolism and nerve function. Adequate intake of thiamine through diet or supplementation is important to maintain overall health and prevent deficiency.
