Here we discuss the structure and synthesis of various Vitamins.
Vitamin A influences growth in animals, and also apparently increases resistance to disease. Night blindness is due to vitamin A deficiency in the human diet, and a prolonged deficiency leads to hardening of the cornea, etc. Vitamin A occurs free and as esters in fats, in fish livers and in blood. It was originally isolated as viscous yellow oil, but later it was obtained as a crystalline solid, m.p. 63-64°C.

Chapter Summaries
- Vitamin A: This chapter covers the structure, properties, and synthesis of vitamin A, highlighting its role in animal growth, resistance to disease, and the prevention of night blindness. The chapter discusses the various chemical reactions and transformations involved in the identification and synthesis of vitamin A.
- Vitamin B6: This chapter delves into the structure and synthesis of vitamin B6, also known as pyridoxin. It explores the chemical properties of pyridoxin, including its behavior as a weak base and the presence of hydroxyl groups. The chapter details the experimental procedures used to determine the structure of pyridoxin, including oxidation reactions and spectral analysis.
- Vitamin H: This chapter provides a comprehensive overview of vitamin H, also known as biotin. It explores the historical discovery of biotin, its biological roles, and the determination of its structure. The chapter highlights the different chemical reactions and transformations involved in elucidating the structure of biotin, including hydrolysis, oxidation, and condensation reactions.
- Vitamin B1: This chapter focuses on the structure and synthesis of vitamin B1, also known as thiamine. It discusses the role of thiamine in preventing beriberi and the identification of its chemical components. The chapter details the chemical reactions used to decompose thiamine into its constituent fragments and analyze their properties. This chapter also includes the process of synthesizing thiamine based on the identified fragments.
