Carbohydrates Carbohydrates are better known to students as sugars and starches. Monosaccharides or simple sugars such as glucose and fructose C6H12O6 function as energy source in cells during cellular respiration and are also used to build cell structures and other organic molecules within the cells.

Disaccharides are composed of two monosaccharides joined together. Sucrose table sugar is a disacharide composed of one glucose and one fructose molecule.

Are long chains of monosaccharides bond together. Plants store excess glucose in the form of starch, a polysaccharide composed of long chains of glucose. Starches can be found in potatoes, rice, wheat, corn, bananas, peas, beans, lentils, and other tubers, seeds and fruits of plants.

Animals and humans store excess glucose in the form of glycogen in the liver and muscles. Between meals the liver breaks down glycogen to glucose and releases it into the blood stream to supply glucose to cells in need.

Other important polysaccharides are cellulose and chitin. Cellulose makes up the cell wall of plants whereas chitin provides structure to fungi and the exoskeleton of arthropods.

Lipids A lot of lipids function as long-term energy storage. One gram of fat stores more than twice as much energy as one gram of carbohydrates. Lipids are also an important component of the cell membrane.

Lipids consist of glycerol and fatty acids "tails". The fatty acid "tails" are long chains of carbon and hydrogen that contribute to the non-polar behavior of fats - they don't mix with polar water.

The fatty acid chains can be saturated, with all carbons saturated with hydrogen atoms forming a straight chain without double bonds. Unsaturated fatty acids contain double bonds within the carbon chain, which results in a bend of the chain. Proteins Proteins are complex, specialized molecules composed of carbon, oxygen, hydrogen, nitrogen and sometimes sulfur.

The building blocks of proteins are amino acids. There are 20 different amino acids that combine to form polypeptides proteins. The different amino acids are similar in structure: The different amino acids have different side chain, but are otherwise identical.

Proteins have many important roles in organisms.MACROMOLECULES IN Nutrients LAB. In this lab, with the use of indicators as chemical detection tools, you will analyze a variety of foods for the presence of nutrients. Detection is based upon observing a chemical change that takes place most often a change in color.

The literal definition of the term macromolecule implies large molecule. In the context of science and engineering, the term may be applied to conventional polymers and biopolymers (such as DNA.

Macromolecules are giant molecules with many atoms and very large masses for a molecule. Cells can combine small organic molecules into large macromolecules, forming a higher level in the biological hierarchy.

Carbohydrates, lipids, proteins and nucleic acids are the four major classes of organic compounds in cells. In biology, a macromolecule is a term used to contrast a micromolecule (which is smaller in size and in molecular weight). In chemistry, though, a macromolecule is an aggregate of two or more molecules held by intermolecular forces and do not readily dissociate.

A macromolecule is a very large molecule made up of smaller units called monomers. The monomers may be the same or slightly different.

Macromolecules are formed by dehydration reactions in which water molecules are removed from the formation of bonds.
