Which group of vitamins dissolves in fats?

The group of vitamins that dissolves in fats is known as fat-soluble vitamins. These vitamins include A, D, E, and K. Their ability to dissolve in fat means they can be stored in the body's fatty tissues and liver, allowing them to be utilized when needed. This storage capability is significant because it means that these vitamins do not need to be consumed daily like water-soluble vitamins, which are excreted more readily and require more regular intake to maintain adequate levels in the body.

On the other hand, water-soluble vitamins, such as B vitamins and vitamin C, do not dissolve in fat and are generally lost through urine, which necessitates regular consumption through diet. Essential vitamins refer more broadly to those the body needs but does not specify solubility, while trace vitamins isn't a standard category used to classify vitamins. Hence, understanding that fat-soluble vitamins are distinctly defined by their ability to dissolve in fats is crucial in nutritional studies and practices.
