Arachidonic acid sodium salt
Based on 60 publication(s) in Google Scholar
Arachidonic acid (Immunocytophyt) sodium salt is a polyunsaturated omega-6 fatty acid and a major constituent of biomembranes. Arachidonic acid sodium salt also acts as the substrate for various lipid mediators, such as prostaglandins (PGs). Arachidonic acid sodium salt improves cognitive response and cardiovascular function.
