Abstract: Algae, which are of great importance for the marine ecosystem, are also rich in high-value bioactive compounds. These valuable bioactive compounds are fat and fatty acids, proteins, carbohydrates (sugars), pigments, minerals, vitamins, sterols, antioxidants and polyphenols. With the industrial production of these compounds, their areas of use are expanding day by day. Some bioactive compounds with the highest industrial production and utilization and their commercial dimensions have been evaluated.
