Chemical Structure of Vitamins and Minerals

Chemical Structure of Vitamins and Minerals. Vitamins and minerals are nutrients required in very small amounts for essential metabolic reactions in the body. Some diseases caused by vitamin deficiencies, such as scurvy, have been recognized since antiquity, but it was only in the 20th century that systematic nutritional studies identified the chemical structures of many of these essential ...

Mineral - Wikipedia

The latter mineral can only be formed on Earth by meteorite impacts, and its structure has been composed so much that it had changed from a silicate structure to that of rutile (TiO 2). The silica polymorph that is most stable at the Earth's surface is α-quartz. Its counterpart, β-quartz, is present only at high temperatures and pressures (changes to α-quartz below 573 °C at 1 bar). These ...

The importance of crystal structure. The graphite-diamond mineral pair is an extreme example of the importance of crystal structure. These two very different minerals have exactly the same chemical formula (C), but the crystal structure of the two minerals is very different. In graphite, carbon atoms are bonded together along a flat plane, as shown in Figure 3.

The Learning Zone: What is a Mineral?

Each mineral is defined by its particular chemical composition and crystal structure. To explain what a mineral is properly, we have to introduce you to a bit of chemistry. Minerals are made up of chemical elements. A chemical element is a substance that is made up of only one kind of atom. Have you heard of oxygen, hydrogen, iron, aluminium, gold and copper? These are all chemical elements ...

Mineral - Simple English Wikipedia, the free encyclopedia

Minerals are substances that are formed naturally in the Earth.They are the building blocks of rocks. Minerals are usually solid, inorganic, have a crystal structure, and form naturally by geological processes.. The study of minerals is called mineralogy.. A mineral can be made of single chemical element or more usually a compound.There are over 4,000 types of known minerals.

mineral Types Uses Britannica

Minerals display a highly ordered internal atomic structure that has a regular geometric form. Because of this feature, minerals are classified as crystalline solids. Under favourable conditions, crystalline materials may express their ordered internal framework by a well-developed external form, often referred to as crystal form or morphology.

The two kinds of minerals are: macrominerals and trace minerals. Macro means "large" in Greek (and your body needs larger amounts of macrominerals than trace minerals). The macromineral group is made up of calcium, phosphorus, magnesium, sodium, potassium, chloride, and sulfur. A trace of something means that there is only a little of it. So even though your body needs trace minerals, it
