This role in energy metabolism comes from its ability to act as a coenzyme. Different configurations of thiamin and phosphate are made in the intestine to facilitate vitamin B1’s role in metabolism. Thiamin diphosphate (two phosphate molecules connected to free thiamin molecules) is the most important form.
The forms of thiamin help other enzymes start chemical reactions that break down carbohydrates, proteins, and lipids. The process turns starches, sugars, amino acids, and fats into usable energy for the cells of your body.
Thiamin isn’t just involved in energy metabolism. It’s impact on cellular sugar production makes it essential for the synthesis of DNA and RNA. Vitamin B1 also helps build fatty acids and supports healthy cellular function.
