2.4.2 Magnesium (Mg)

Magnesium is also present in bone in the body and in the soft tissues, although in much lower quantities than calcium. It is important in the activity of more than 300 enzyme systems, in particular those using ATP. It is involved in the synthesis of proteins and in many other reactions in the body. In plants, magnesium is part of the chlorophyll molecule, so it is present in green vegetables and is found widely elsewhere in the diet, so intake is normally adequate. In some areas, there are lo

4.4 The ongoing story

At the time of writing (2006), the Golden Rice tale is an unfinished story. Some of the developments of the last five years are summarised here.

One area of ongoing scientific dispute is the question of whether the enriched rice can contribute significantly to the alleviation of vitamin A deficiency. We have seen that Shiva estimated that at best 100 g of rice a day would provide 4.4% of the recommended daily allowance. More sophisticated theoretical models, published since that time, h

2.8 The angles of a triangle

The sum of the angles of any triangle is 180°. This property can be demonstrated in several ways. One way is to draw a triangle on a piece of paper, mark each angle with a different symbol, and then cut out the angles and arrange them side by side, touching one another as illustrated.

2.2 Direct proportion

In a recipe the quantity of each ingredient needed depends upon the number of portions. As the number of portions increases, the quantity required increases. The quantity per portion is the same. This is called direct proportion. The quantity is said to be directly proportional to the number of portions. If 2 potatoes are required for one portion, 4 will be required for two portions etc. A useful method for direct proportion problems is to find the quantity for one and multiply by the

1.4 Converting ratios from fractions to decimals

Although ratios are often given as fractions, they can also be expressed as decimals. You need to deal with a mixture of fractions and decimals, and to compare ratios given in either form, so you need to be able to convert between the two forms.
