Ascorbic Acid vs. Citric Acid — What's the Difference?

On the other hand, citric acid is a weak organic acid primarily found in citrus fruits like oranges, lemons, and limes. Unlike ascorbic acid, which serves primarily as a vitamin, citric acid is known for its flavor enhancing and preservative properties. It imparts a sour or tangy taste to foods and beverages. Moreover, citric acid is used in the preservation of a range of products due to its ability to chelate metals and function as an antioxidant.

From a chemical perspective, while both ascorbic acid and citric acid are acids, their structures and molecular compositions differ. Ascorbic acid possesses antioxidant properties, making it essential in defending the body against free radicals. Citric acid, in its turn, plays a key role in the citric acid cycle (Krebs cycle) in cellular respiration, facilitating energy production.

Ascorbic acid and citric acid are both organic compounds, but they differ in their structures, functions, and sources. Ascorbic acid, widely known as vitamin C, is an essential vitamin for humans. It plays critical roles in collagen synthesis, antioxidant functions, and aids in the absorption of iron. Many consider ascorbic acid vital for skin health, wound healing, and overall immune function.

To sum up, while both ascorbic acid and citric acid are naturally occurring and beneficial organic compounds, they differ significantly in their functions, structures, and sources. It's crucial to note that they aren't interchangeable, despite sometimes being mentioned in similar contexts, especially in food and health.
