To determine: Whether a phytochemical and/or functional food offers a safe and sensible solution to improve the health.
Introduction: Phytochemicals are naturally occurring plant chemicals that are produced either through primary or secondary metabolisms. In foods, phytochemicals impart colors, aromas, tastes, and other characteristics. Several phytochemicals have biological activity in the body. Functional foods are the enriched and enhanced foods that have a positive effect on health beyond the essential nutrients.

- Describe the similarities and differences in the absorption and regulation of iron and zinc. What is the mechanism/process that makes phytates affect iron and zinc absorption? How can we enhance the absorption of these sources? Which is the better choice—to eat processed foods that have been enhanced with phytochemicals or to eat natural foods that are rich in phytochemicals? Explain your answer. Look up any uncommon food item in our culture, and find out the nutritional content (what nutrients can this item provide us both macro and micro?

- 3. (a) White asparagus (as opposed to green asparagus) is typically grown under a layer of mulch in the dark. Would you expect this plant to have high or low levels of fructose-2,6-bisphosphate. Explain your answer. (b) Another variety of asparagus has increased concentrations of anthocyanin, a pigment that appears purple in color. What could be an advantage for this plant over green asparagus? (c) Purple asparagus also tastes slightly sweeter than the other two other varieties. Based on what you know about carbon fixation in plants, what could be the reason for this flavor?arrow_forwardAcid rain can have a pH between 1.5 and 5.0. The effect of acid rain on the environment depends on the pH of the rain and the characteristics of the environment. It appears that acid rain has a negative effect on plants. The scale below shows the pH of normal rain. Provide the information requestec below that should be included in a research plan to test the effect of pH on the early growth of bean plants in the laboratory. Which of the following would be the dependent variable? (choose all that apply)kr Normal rain 12 3 45 6 7 89 10111213 14 pH Scale a. the pH of the rain b. the type of plant c. the amount of rain d. the height of the plant Se Which statement best describes the growth curve seen below: a. It shows only exponential growth b. It shows a decline in population c. It shows growth slowing and then remaining steady d. It shows extinctionarrow_forwardI have recently purchased a bottle of essential oil to be used as mosquito repellent. Classify the essential oil into the relevant group of secondary metabolites. Describe the distinctive scent produced and name the plant in which this essential oil could be (i) extracted. What are the roles of terpenes in plant defense and provide ONE (1) suitable solvent to be used for extraction? (ii)arrow_forward
- University of Seville Researchers from the Department of Pharmacology at the University of Seville have recently published a study in which they state that diets supplemented with aqueous extract of Annona muricata L. leaves can prevent the symptoms associated with fibromyalgia, so improving the lives of these patients. Leaves of the species Annona muricata L. come from a tree of between 4 and 6 metres in height, from the botanical family Annonacese. They are simple leaves, oblong and egg like or oblong and elliptical in shape and between 5 and 15 cm in length. This species is native to the tropical areas of the Americas and is especially abundant in the Amazon region. It is usually cultivated for its medicinal use. The leaves have different ethnomedical uses according to their country of origin. The most important uses in traditional medicine, scientifically validated in pre-clinical tests, are for inflammation, pain, infections, diabetes and cancer. "The consumption of extract of…arrow_forwardLavendar (Lavandula spp.) Where is the species native to and what type of plant is it? Is the plant currently used in modern medicine (i.e. current status)(provide examples of medications that use Lavendar)? What medicinal properties does it have? What ailments does it treat? Please be detailed in your answer.arrow_forwardPlease name and describe the functions of the five most important minerals for plant growth: N, K, Ca, Mg & P (Table 14.3).

We have figured out which elements are essential by using hydroponic culture, which involves growing plants in clay instead of soil. Micronutrients of plants include carbon, oxygen, and hydrogen. Plants only require a small amount of macronutrients which include zinc, copper, and iron.
