Algal polyunsaturated fatty acids and effects on plankton ecology and other organisms

A review and discussion of the effects of algal polyunsaturated fatty acids (PUFAs) on phytoplankton and zooplankton ecology and their effects on other animal systems. Topics discussed also include the relationship of cyanobacterial classification to PUFA occurrence, lipid concentrations occurring in the aqueous environment, the general effect of microalgae on zooplankton, and how algal PUFAs may be exerting their inhibitory and toxic effects

A spectrophotometric study of the behavior of carbohydrates in seventy-nine per cent sulfuric acid

The spectral characteristics of solutions of eighteen representative monosaccharides in 79 per cent sulfuric acid have been determined for solutions maintained for 2 hours at 25° and 15 minutes at 100°. The use of these data for the identification of ketohexoses and 6-desoxyaldohexoses has been pointed out, as has their application to the quantitative determination of certain monosaccharides when present singly or in admixture with other monosaccharides, either as the monosaccharides or as components of oligosaccharides and polysaccharides
