7.1 Introduction

Vitamins are organic compounds that are not produced by body cells but essential for metabolism that occur within the body [1]. Vitamins play an important role in carbohydrate, fat, and protein metabolism, healthy development of the body, immunity against infections, digestive functions. For this reason, when vitamins taken from foods are deficient, disorders occur in metabolism. Vitamins are called water and oil‐soluble vitamins according to their chemical properties and structures. Vitamins are the most essential organic compounds in terms of nutrition. Vitamins are classified in two groups as water‐soluble (vitamins B and C) and fat‐soluble (vitamins A, D, E, and K) (Figure 7.1). The fat‐soluble vitamins are stayed for longer time in the body and stored in the body and liver. The water‐soluble vitamins are unable to store in the body and are excreted in the urine [2].
