Which of the following is oligosachharide .. maltose fructose starch or glucose
Answers
Maltose – oligosachharide made by few units of saccharide
Fructose – mono saccharide
Starch –poly saccharide
Glucose – mono saccharide
Carbohydrates are organic compounds contain poly hydroxyl group along with either aldehyde or ketone functional group.
The carbohydrate is classified on the presence of ring in the structure.
Monosaccharide carbohydrate: it contains only one ring in their structure.
Disaccharide carbohydrate: it contains two rings in their structure.
Polysaccharide carbohydrate: Polysaccharide carbohydrate contains three or more than three rings in their structure.
Mono-saccharides: The simplest carbohydrates, such as glucose, are mono-saccharides, also called simple sugars, because they contain only a single sacchride molecule.
Disaccharides: Disaccharides consist of two mono-sacchride units joined together, such as glucose and fructose linked to form sucrose (table sugar) or two glucose units to form maltose.
Polysaccharides: Polysaccharides are polymers containing many monosaccharide units, up to several thousand. For example natural starches contain about 75% amylopectin and 25% amylose, both of which are polymer of glucose units joined by glycosidic linkages
