Abstract Thiamine (vitamin B 1 ) is essential for human metabolism and is particularly important for proper brain functioning. It was the first of the B complex vitamins to be isolated, which is why it’s called B1. CoA-dependent oxidative decarboxylation of pyruvate is catalyzed by pyruvate dehydrogenase multienzyme complex (PDC) with NAD+ as an electron acceptor in most organisms involving mammals and higher plants. Thiamine (thiamin or vitamin B1), as thiamine pyrophosphate (physiologically active form), plays an important role in the metabolism of both carbohydrate and the branched-chain amino acids. Thiamine decomposes if heated. It was not until about 25 years later that the name Thiamine was coined for the vitamin. Vitamin B complex, several vitamins that traditionally have been grouped together because of loose similarities in their properties, their distribution in natural sources, and their physiological functions, which overlap considerably.

In the human body about 80% of thiamin are presented in the form of thiamin diphosphate (TDP). Thiamine is a required cofactor in the Pentose Phosphate Pathway and its involvement leads to producing a number of crucial molecular products including neurotransmitters. NADPH (B1) and FAD (B2) cofactors should be promoted. 1.4.1 Thiamin (vitamin B1) Thiamin (thiamin pyrophosphate is the metabolically functional form) has crucial roles as a cofactor for several enzymes participating in intermediary metabolism (DH, 1991; WHO and FAO, 2004).Thiamin is equally spelled as thiamine in many text books.
