Water Information

The human body is more than 60 percent of water. Three quarters of the earth's surface is covered with water. However, 98 percent is salt water and not fit for consumption.


MACROMOLECULES

A macromolecules is a very large molecule commonly created by polymerization of smaller subunits. A molecule of high relative molecular mass, the structure of which essentially
comprises the multiple repetition of units derived, actually or conceptually, from
molecules of low relative molecular mass.Macromolecules often have unusual physical properties.

CARBOHYDRATES

Carbohydrates

Three types of carbohydrates are sugar , starch , and fiber. The function of carbohydrates are providing energy and regulation of blood glucose, sparing the use of proteins for energy, breakdown of fatty acids and preventing ketosis, biological recognition processes, flavor and sweetener, dietary fiber. Examples of carbohydrates would be pasta, bread, candy, sugar, soda, flour, pops, pop-tarts, cereal, potatoes, and corn.


Proteins

Types of proteins would be fibrous, globular, and membrane. Functions of proteins are repair and maintenance, energy, transportation and storage of molecules. Examples of proteins are carbon, hydrogen, oxygen, and nitrogen.


Lipids

Types of lipids are structural and storage lipids. Lipids have several biological uses that include energy storage, acting as structural components of cell membranes.


Nucleic Acids

Types of nucleic acids are ribonucleic acid (RNA) and deoxyribonucleic acid (DNA). The function of nucleic acids is to store and transmit.
