Biologically Important Proteins : Carbohydrates, Proteins, Lipids, And Nucleic Acids

Different reagents were used for the tests with the reagents reacting with the molecules in a specific way indicated by a change of color. Controls were provided to ensure integrity of the process. The results indicated the presence or absence of the organic molecules in the various substances provided. They proved that using these tests, one can accurately determine what organic molecules a substance contains. This will help in determining the composition of various substances within the cell or even outside the body and how they affect normal cell

The most common macromolecules found in living organisms are lipids, carbohydrates, proteins and nucleic acids. Briefly, the meaning of macromolecules is that they normally contain two or more molecules in them and their main functions are to store energy, information and much more. Most foods are known to be combinations of macromolecules. While some of these compounds can be detected by taste tests, many cannot. Scientists then use certain tests to determine the presence of macromolecules.

2. Cellular level- molecules, in turn, associate in specific ways to form organelles, basic components of the microscopic cells. Cells are smallest units of living things.

There are millions of different organic compounds. Most of them are found in mixtures and in order to achieve a pure form they need to be separated, isolated, and purified. However, there are endless numbers of possible mixtures, which make it impossible to have a pre-designed procedure for every mixture. So chemists often have to make their own procedures. The purpose of this experiment was to prepare the student to the real world by them designing their own procedure which will help them understand the techniques of separation and purification better. The goal was to extract two of the components of the

Introduction: The fundamental techniques of organic chemistry lab, commonly known as SIPCAn, include separation, isolation, purification, characterization, and analysis (1). Through SIPCAn, students learn the fundamental techniques of organic chemistry laboratory. Mastering these techniques are necessary in order to perform more complicated experiments and to carry out organic reactions and synthesis. The information gained from SIPCAn included boiling point, melting point, and density can be used to identify unknown compounds. Simple distillation was used to purify a compound by separating it from a

This section will dealt with the main organic molecules in living things: carbohydrates, fats ( lipids ), proteins and nucleic acids.

is the genetic material of all organisms, it is the molecule of life and it

There are three types of Organic molecules, examples of them are protein, fats/oils, starch and monosaccharides. Proteins provide structure, movement, and energy. Fats/oils are used for long term energy storage, insulation and cushioning. Monosaccharides and starch are both used mainly for energy storage Hypothesis: Using this

Carbohydrates are organic compounds that are made up of carbon, oxygen, and hydrogen. Carbohydrates are used as a point of supplies of energy. The energy is stored and can be used in the future.

There are four types of biomolecules, carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates are large chains of sugar found in food and living tissues. This includes sugars, starch, and cellulose. They have the same ratio of hydrogen and oxygen that water has, 2:1. They are broken down to release energy in the animal body. Lipids are any organic compounds that are fatty acids and don’t dissolve in water but do in organic solvents. Fatty acids can be found in natural oils, waxes, and steroids. Proteins are macromolecules that do everything in the cell. They are tools and machines that make things happen. Nucleic acids are long strands of nucleotides, and function primarily in storage and transmission of genetic information. There are two types of nucleic acids, DNA and RNA. DNA is the genetic material of all cellular organisms, and RNA sends out messages from the information that is held in the DNA.

Although organic reactions have been conducted by man since the discovery of fire, the science of Organic chemistry did not develop until the turn of the eighteenth century, mainly in France at first, then in Germany, later on in England. By far the largest variety of materials that bombard us are made up of organic elements. The beginning of the Ninetieth century was also the dawn of chemistry, all organic substances were understood

Organic compounds are, by definition, any chemical compound containing carbon. These compounds include carbohydrates, polysaccharides, lipids, proteins, and nucleic acids. Each one of these compounds has a different purpose. Carbohydrates give energy to cells when consumed. Lipids are basically the fats of a cell. Proteins are the building blocks of muscle in a cell. Nucleic acids are used to transfer genetic information from one cell to the other.
