A balanced diet can normally meet all the body's chemical element requirements. Supplements may be required when requirements are not adequately met by the diet (for example, vegans should supplement calcium, which is found mainly in dairy products), or when deficiencies arise from pathology or injury.

MINERALS - Magnesium Magnesium plays an important role in the production and transport of _________ . It is also important for the contraction and relaxation of muscles . Magnesium is involved in the synthesis of protein , and it assists certain enzymes in the body. Over 300 enzymes require magnesium ions for their catalytic action, including all enzymes using or synthesizing ATP, or those that use other nucleotides to synthesize DNA and RNA . Human magnesium deficiency is common, with only approximately 32% of the United States meeting the RDA. Low levels of magnesium in the body have been associated with development of illnesses such as asthma, diabetes, and osteoporosis.

WATER All chemical reactions of living things take place in water. Many types of metabolic wastes can only be eliminated from body when dissolved in water. •T h e catalysis of materials requires water. You may be able to survive weeks without food, but wouldn’t last more than a few days without water. Human body ~ 65% water (even dense tissue like bone is 33% water). Food provides ~ 20% of total water intake. Remaining 80% from water and other beverages. Institute of Medicine advises men consume roughly 3.0 liters (~ 13 cups) total beverages daily & women consume 2.2 liters (~ 9 cups). Q: What are some reactions that we have discussed in class that involve water? From the Virtual Cell Biology Classroom on ScienceProfOnline.com
