Introductory Remarks In this monograph I write about phytochemicals, ie, complex chemicals found in plants, notably in fruits and vegetables — with the focus on the phytochemicals rather than on their sources.

This review is not comprehensive, it is simply a first attempt at classification of phytochemicals that have attracted my attention. Many phytochemicals have not been included.

Isoprene Phytochemicals with antioxidant properties tend to be brightly colored because they contain chromophores, ie, a series of alternating single-bonded and double-bonded carbons.

Isoprene is often the building block of such units. The darkest green vegetables contain the most chlorophyll, and vegetables with the most chlorophyll require the most antioxidants. Green will mask the other colors, when other-colored antioxidant phytochemicals are present.

Many phytochemicals have an anti-carcinogenic anti-cancer action by: Phytochemicals are not classified as vitamins with official RDA values, but they can contribute greatly to health and well-being.

We are adapted to a world that contains phytochemicals in our diet. The macula of the eye is adapted to concentrate the yellow caroteniods lutein and zeaxanthin to protect against harmful blue light. Although the emphasis is on the positive effects of phytochemicals, note that very many can be toxic and harmful.

Plants containing the most harmful phytochemicals are usually not treated as foods. Oxalic acid is included here because it is primarily harmful and is found in plant foods.This experiment examines the effects of different pH level of vinegar on the growth of bean plants. Materials used in this experiment consist of: water (pH 6), vinegar with the pH level of 3, 4 and 5 (each one were made before experiment), beans, soil, and pots.5/5(4).

Organic farming is a phrase coined early in the 20th century in reaction to rapidly changing farming practices to describe what other species use, and used, to farm without synthetic chemicals.

Organic farming continues to be developed by various organic agriculture organizations today. It relies on fertilizers of organic origin such as compost manure, green manure, and bone meal and places.

Forward: Although this depression treatment by magnesium essay was written originally to address the role of magnesium as a depression treatment, the role of magnesium deficiency as cause of vast other morbidity and mortality is also addressed.

In my experiment lower pH water made plants grow much faster than high pH, at the end the one with a water pH of 6 grew to 6 inches and the plant watered at a pH of 8 only grew to in.

This is because flowering plants grow at a much higher rate when they absorb certain nutrients, and these nutrients are easiest to absorb when the pH is lower.
