Essential nutrients
These are the organic compounds present in the food that provide nourishment essential for the development and growth of our body. Nutrients not only provide us with the required energy to carry out various biological processes but are also the building blocks for repair and growth in our bodies.
Vitamins
The vitamins are organic molecules required in low concentration for the proper functioning of the body. They cannot be generated in the organism and are taken into the body through the diet. The lack of proper vitamins results in diverse deficiency disorders. They are thus called essential nutrients. The important vitamins are vitamin A, vitamin B complex, vitamin C, vitamin D, vitamin K, and vitamin E.
The question is as follows:
What is the recommended daily intake allowance for this vitamin? Assume the person is between the ages of 20-30 years of age in good health.

![### Structural Representations of Essential Vitamins
This image illustrates the chemical structures and 3D models of four essential vitamins: Vitamin C, Vitamin A, Niacin (Vitamin B₃), and Vitamin E. Each vitamin is represented by a molecular formula and a ball-and-stick model, providing insight into their structural composition.
#### a. Vitamin C
- **Chemical Structure**: Displays a cyclic structure with multiple hydroxyl (OH) groups, highlighting its nature as a water-soluble vitamin.
- **Ball-and-Stick Model**: The 3D model shows the spatial arrangement of the atoms, with red spheres representing oxygen, black spheres for carbon, and white for hydrogen.
#### b. Vitamin A
- **Chemical Structure**: Features a long hydrocarbon chain with conjugated double bonds and a terminal ring structure.
- **Ball-and-Stick Model**: Demonstrates the elongated chain and the positioning of atoms, with similar color coding as Vitamin C.
#### c. Niacin (Vitamin B₃)
- **Chemical Structure**: Consists of a pyridine ring with a carboxyl group, emphasized by its role in metabolic processes.
- **Ball-and-Stick Model**: Highlights the aromatic ring structure, with an additional blue sphere indicating the presence of nitrogen.
#### d. Vitamin E
- **Chemical Structure**: Composed of a chromanol ring with a long hydrocarbon tail, representing its lipid-soluble nature.
- **Ball-and-Stick Model**: Displays a bulkier tail compared to the head, signifying the hydrophobic characteristics of Vitamin E.

![Most vitamins can be classified as either as fat soluble, which results in their tendency to accumulate in the body (so that taking too much can be harmful), or water soluble, which results in their tendency to be quickly eliminated from the body in urine.
