Groups of cells held together by electrical charges Posted By : ...

Theyre simply groups of cells held together by electrical chargesthat keep the cells in place so that a piece of this page or apiece of your finger doesnt go spinning off into space. Individualcells stay intact because they have a cell membrane, an outer skinthat serves as neat and tidy packaging for the cell. Onerequirement for healthy cell membranes is  drumroll please cholesterol.

A whopping 90 percent of all the cholesterol in your body is inyour cell membranes. The cholesterol protects the integrity of thecell membrane, helping to keep it flexible and strong. If you wereto diet so stringently or use so many cholesterol-lowering drugsthat your cholesterol level fell to zero (an impossibility by theway), your cell membranes would be very dry and easily torn. Thestuff inside the cells would leak out, and cells would die all overthe place. That would sort of put an end to the whole darn shootinmatch.

Every healthy body cell needs some cholesterol, and so does everyhealthy brain. Atoms are the basic building blocks of elements hydrogen, oxygen, carbon, and all their chemical cousins. Each atomcarries the name of the element it represents (such as hydrogen).In addition, each atom has a shorthand symbol  call it a nickname such as H for hydrogen.

Sometimes, an atoms shorthand name seems totally divorced from itsfull name. For example, lead atoms are called, well, lead atoms,but the symbol for a lead atom is Pb, from plumbum, the Latin wordfor lead. There are also elements and atoms named for human beings.For example, seaborgium is named for Nobel Laureate Glenn T.Seaborg; its shorthand symbol is Sg.

Individual atoms form bonds with other atoms to create clusters ofatoms called molecules. To write the name of a molecule  itsformula  you write the symbols of the different atoms that themolecule contains and the number of each type of atom right afterthe symbol. For example, if I write H2O, the formula for the watermolecule, you know immediately that a water molecule has twohydrogen atoms and one oxygen atom. A body cell, the smallestindependent unit of a living creature, is a collection ofmolecules. And you, wonderful reader, are a collection of cells.
