Q2. a) Discuss the structure and physio - chemical properties of any one of the water soluble vitamins.
ANS- Thiamin (Vitamin B1)
Thiamin (also spelled thiamine) is a water-soluble B vitamin, previously known as vitamin B1 or aneurine. Isolated and characterized in the 1930s, thiamin was one of the first organic compounds to be recognized as a vitamin. Thiamin occurs in the human body as free thiamin and as various phosphorylated forms: thiamin monophosphate (TMP), thiamin triphosphate (TTP), and thiamin pyrophosphate (TPP), which is also known as thiamin diphosphate.
Deficiency
Beriberi, the disease resulting from severe thiamin deficiency, was described in Chinese literature as early. Thiamin deficiency affects the cardiovascular, nervous, muscular, and gastrointestinal systems. Beriberi has been termed dry, wet, or cerebral, depending on the systems affected by severe thiamin deficiency.
