bio 4.1.1- Compare the structures and functions of the major biological molecules (carbohydrates, proteins, lipids, and nucleic acids) as related to the survival of living organisms.
There are four major biological molecules that aid in our survival: carbohydrates, proteins, lipids, and nucleic acids.

Carbohydrates-
Carbohydrates are an important source of energy. They can be found in breads, cereals, fruits, and vegetables.
Monosaccharides: The basis of carbohydrates are single sugars which are called monosaccharides. These consist of glucose, fructose, and galactose. Glucose, especially, is very important in our bodies because it is a major source of energy in our cells.
Disaccharides: These are formed when two monosaccharides are bound together. There are three main disaccharides: sucrose, lactose, and maltose.

Proteins-
Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body’s tissues and organs.
Enzymes: These proteins are used to speed up chemical reactions.
Hormones: These basically effect the function of the cells in the body by carrying messages from glands to cells and they also maintain chemical levels in the bloodstream to achieve homeostasis.
Collagen: This is used to form bones, tendons, ligaments, and cartilage.
Hemoglobin: This is very important in our bodies because it is what transports oxygen throughout our bodies.

Lipids-
There are several different types of lipids in our bodies: fats, oils, waxes, and steroids. Your body uses fats as a supply and source of energy. The steroids in your body include some of your hormones. Other lipids are used to as an outer layer of all of your cells.

Nucleic Acids-
These allow organisms to transfer genetic information from one generation to the next. There are two types of nucleic acids: DNA and RNA.
DNA & RNA: The major difference between these two are the sugars in each molecule. DNA has deoxyribose while RNA has ribose. These two are basically the same except deoxyribose has one more OH molecule.
