Effect of altered dietary n-3 fatty acid intake upon plasma lipid fatty acid composition, conversion of [13C]alpha-linolenic acid to longer-chain fatty acids and partitioning towards beta-oxidation in older men. Spirulina is high in protein and vitamins. The seaweed also contain significant amounts of carbohydrate compounds, which are most beneficial to the body, and vegetable protein. Their primary mode of nutrition is phototrophy, but they can supplement growth by phagotrophy and/or osmotrophy when light is limiting (e.g., Dinobryon divergens, Heterokontophyta).
