Question
What are the two main 6-carbon sugars in organisms? Why fructose sometimes called fruit sugar? What are disaccharides made from? Name three main disaccharides in organisms. Why do all monosaccharide react with Benedict's reagent? Why only some disaccharides (e.g. maltose and lactose) react with Benedict's reagent? What did you learn about the specificity of the Benedict's and Lugol's reagents? What are the elements that make up a protein? What are the monomers that make up a protein? And how many of them? Diagram an amino acid and label the groups.Explanation / Answer
Q.5a). glucose,fructose.
Q.6a). Fructose is a monosaccharide, or single sugar, that has the same chemical formula as glucose but a different molecular structure. Sometimes called fruit sugar,As fructoseis found in fruit, some vegetables, honey, and other plants.
Q.7a).A disaccharide (also called a double sugar or biose) is the sugar formed when two monosaccharides (simple sugars) are joined by glycosidic linkage. Like monosaccharides, disaccharides are soluble in water. Three common examples are sucrose,lactose, and maltose.
8.Qa)..All monosaccharides are reducing sugars; they all have a free reactive carbonyl (C=O) groups
Q9a). Some disaccharides have exposed carbonyl groups and are also reducing sugars. Other disaccharides, such as sucrose, are non-reducing sugars and will notreact with Benedict's solution.
10.Qa). Benedict to test-the presence of reducing sugars and
Lugol's to- test the presence of starch and glycogen.
11Qa). Proteins are composed of molecules called amino acids, and each amino acid contains four elements: hydrogen,oxygen, nitrogen and carbon. Some might also contain a fifth element,sulfur.
Q12a). Amino acids are natural monomers that polymerize at ribosomes to form proteins.
13Qa). H2N-C-CooH and 2 more groups present on carbon are R(variable),H(hydrogen)
NH2(amino),CoOH(carboxyl).
