Hydroxy long-chain fatty acids in fungi

Area of Science:

• Biochemistry
• Mycology
• Biotechnology

Background:

• Hydroxy long-chain fatty acids are prevalent in eukaryotes with significant physiological roles.
• Evidence suggests these compounds are also common and vital in fungi.
• Hydroxy-polyunsaturated fatty acids (hydroxy-PUFAs) are of biotechnological interest due to their potential as high-value lipid products for medical applications.

Purpose of the Study:

• To review the production of hydroxy-PUFAs by yeasts and other fungi.
• To discuss the occurrence of various hydroxy long-chain fatty acids in fungi.

Main Methods:

• Literature review focusing on hydroxy-PUFA production in fungi.
• Analysis of hydroxy-PUFA origins, including lipoxygenase and cyclooxygenase pathways.
• Discussion of other hydroxy fatty acids associated with cytochrome P-450 monooxygenase activity.

Main Results:

• Hydroxy-PUFAs from lipoxygenase activity are found in most fungi.
• Hydroxy-PUFAs from cyclooxygenase activity (prostaglandins) are primarily in Oomycota and Dipodascopsis yeasts.
• Other hydroxy fatty acids, including 2- and 3-hydroxy-fatty acids, are also present.

Conclusions:

• Fungi are a significant source of diverse hydroxy long-chain fatty acids, particularly hydroxy-PUFAs.
• The enzymatic pathways (lipoxygenase, cyclooxygenase, cytochrome P-450) involved in their production are key.
• Fungal hydroxy-PUFAs represent a promising area for biotechnological development and medical applications.
