How might you test for the presence of a (carbohydrate)simple sugar, disaccharide, polysaccharide, and lipid?

Simple Suagrs can be tested with Benidicts Soultion which turnes from blue to yellow to orange to brown in the presense of a simple sugar when heated in a hot water bath.  Polysaccharides can be tested with iodine which turns purple in the presence of starchs.  There really is no simple test for disaccharides but they can be ruled out by testing for both simple sugars and polysaccharides.  Lipids are not carbohydrates but they can be tested for by a simple paper bag that becomes translucent when smeared with a lipid(like eating potato chips and touching a piece of paper) or with Sudan III which forms red rings on a piece of filter paper.

What level are you and how much information do you want? That question is like asking explain Biochemistry?\n\nAlright the basics: Carbohydrates are made up of sugar molecules they can be one sugar molecule or many in a chain. The simplified answer on their main function is that serve as an energy source, they can be stored in long chains (glycogen, or starch in plants) in the short term and then broken down into smaller sugars and eventually carbon dioxide and water releasing energy.\n\nFats, also called lipids are long carbon chains and are mainly used in cell membranes and as a long term energy store. Look up lipids and triglycerides for more information.\n\nProteins are made up of chains of amino acids which fold into different shapes relating to their functions. Proteins are used as catalysts (called enzymes) and are involved in most of the chemical reactions that occur in the cells. Try looking up enzymes for more information. There are also proteins with different roles in maintaining structure or sending signals around the body.

A starch molecule is made up of 100's of glucose monomers. And each glucose monomer in a starch is linked with another glucose monomer by alpha -1,4 linkage due to which a starch molecule does not have a free aldehyde group which is opresent in a free glucose molecule. At its end it may have a free aldehyde group, but is too small in amount to show the reaction in comparision to a huge glucose monomer. As Benedict's Test is a test to determine presence or absence of a aldehydic group; a starch molecule can not show a positive glucose test. But if a starch molecuse is hydrolysed with help of an acid or amylase enzyme it will certainly show hte positive glucose test.

To know what carbohydrates are made up of, we must classify them first.\n1.Monosachharides-simple sugars like glucose constitute them, each glucose molecule binds with another one by glycosidic bonds to form glycosides.\n2.Disaccharides-eg, sucrose....composed of 2 monosaccharides\n3.Oligosachharides-eg. blood group antigens, composed of 2 to ten monosachharides\n4.Polysachharides-eg. glycogen-composed of more than 10 monosaccharides\nThey can also be classified as aldoses or ketoses, if the reactive group is CHO then its aldose, if C=O then ketoses.\nGlucose is aldose, Fructose is ketose.If u talk of starch, its a polysachharide constituting carbohydrates like amylose and amylopectin.So we have carbon, hydrogen and oxygen compounds involved.\nThat i think is enough about the structure of carbohydrates in context with biology, but do learn to draw the structures.\nIf they contain nitrogen, or aminio group then they are not carbohydrates, they are already derivatives of carbohydrates-glycoproteins, proteoglycans(mucopolysachharides; one example is glucosaminoglycans)

You can work on fruit juices and other beverages like colas etc..carry out small analysis to find out how many of them contain glucose/sucrose ie aldoses and ketoses..u can also determine if they contain carboxylic acids,ascorbic acid etc.u can do benedicts/fehling test and lucas test on the different juices.can determine if any kind of OH group is present in those drinks..wt vitamins,wt minerals present.\nA similar kind of study can be done on toothpastes..take different brands of toothpastes,carry out tests on them as which ones contain Flouride,bleach,whitening powders and whiche all contains sugar.

Sugar is sucrose, a molecule composed of 12 atoms of carbon, 22 atoms of hydrogen, and 11 atoms of oxygen (C12H22O11). \nThe 1st link is just general info, the 2nd may give you an idea for an experiment.

Carbohydrates are sugar polymers or sugar molecules.\n\nThere are two major kinds of sugar polymers, starch (called carbohydrates in dietary context) and cellulose (called fibre in that context). However, the term carbohydrates includes all sugars, too.\n\nThe body breaks down the more complex carbohydrates into sugars which can be transported to the cells or to the liver for storage. In the liver, the sugars will be combined to form starch, which in turn will be broken down again when the body requires more energy than blood sugar levels can provide.

First take 30ml of 1% starch solution and add 6 ml of concentrated HCL acid and distribute them into six test tubes labeled as 'A' TO 'F'. Place them in boiling water bath and take them out at various time intervals like 0', 1', 5', 10', 13' and 15' minutes respectively.\n\nDivide the tubes content into three tubes and do iodine, Fehlings and Benedicts tests in the fractions.\n\nyou can do osazone test in the 15' minute fraction for the conformation of the presence of glucose.\n\nCompare the color developed in different tubes.  It clearly shows difference

These are simple fast tests to detect the presence of carbohydrates in a given sample. These can be modified a little and by using a spec it would be possible to quantify the sugars in a given sample.\nQuestion if more precise would help in giving a specific answer

3, starch. Starch is a polysachride. If broken down, it will be simple sugars.
