Inferred pH in Steam Plant Water Chemistry
Inferred pH means pH calculated from straight and cation conductivity. The calculation can be applied to condensate, feedwater, and boiler water. Although not widely used in the United States, inferred pH is popular in Europe. Some plant chemists find inferred pH useful because it eliminates the need to measure pH directly, which without proper equipment can be a difficult task. This paper disc...
متن کاملThe Role of Chemistry in Plant Systematics
Although the hybrid discipline of biochemical systematics has been a distinct field of study for only about ten years, it has had a telling impact on taxonomic practice. Nevertheless, the chemical approach, with its emphasis on the exact, tends to exlude much of the wealth of natural phenomena that are the backbone of taxonomy. It is necessary for the chemist and biochemist to acquire a better ...
متن کاملThe Chemistry of Plant/Animal Interactions
Chemical approaches to studying plant/animal interactions have led to an appreciation that plant chemistry strongly influences patterns of herbivory. Although this chemistry is often rather complex, two basic factors have emerged: plant chemistry influences herbivores in both positive and negative ways by determining dietary quality of plants and by providing feeding cues. Examination of the re...
متن کاملGlobal biogeography of plant chemistry: filling in the blanks.
It would perhaps come as a surprise to many nonbiological scientists (or even some biologists) to learn that despite our ability to characterize a number of environmental variables, such as climate, along regional or continental gradients, until recently we have had almost no basis for doing so for plant and soil chemistry. New work, including a paper by Han et al . in this issue (pp. 377–385),...
متن کاملAlkamid database: Chemistry, occurrence and functionality of plant N-alkylamides.
ETHNOPHARMACOLOGICAL RELEVANCE N-Alkylamides (NAAs) are a promising group of bioactive compounds, which are anticipated to act as important lead compounds for plant protection and biocidal products, functional food, cosmeceuticals and drugs in the next decennia. These molecules, currently found in more than 25 plant families and with a wide structural diversity, exert a variety of biological-ph...
