Definition

Adjective: 1. Soluble in fats: Describes a substance, particularly a vitamin or other nutrient, that dissolves in and is carried by fats or lipids, rather than in water. This property affects how the substance is absorbed, stored, and transported in the body.

Usage

The term "fat-soluble" is primarily used in nutritional, biochemical, and medical contexts to classify vitamins and other compounds based on their solubility. * It is typically placed before a noun (e.g., fat-soluble vitamin) or used as a predicate adjective. * It is the opposite of "water-soluble."

Examples

• Vitamins A, D, E, and K are fat-soluble vitamins.
• Because it is fat-soluble, this compound is stored in the body's fatty tissues.
• The absorption of fat-soluble nutrients is enhanced when they are consumed with dietary fat.

Advanced Usage

• "fat-soluble vitamins": A standard term for the group of vitamins (A, D, E, K) that are absorbed along with dietary fats and can be stored in the body's liver and fatty tissues.
• The concept is often discussed in contrast to water-soluble vitamins (like Vitamin C and B-complex vitamins), which are not stored in the body to the same extent.

Variants and Related Words
