Expert Solution
Carbohydrates
Chemically, carbohydrates are polyhydroxy aldehydes or ketones. They have the general formula : (CH2O)n.
Depending on their size, they can be:
- monosaccharides: single polyhydroxy aldehyde or ketone. eg glucose, fructose, galactose etc
- disaccharides: two monosaccharides linked via a glycosidic bond. eg Sucrose, lactose, maltose etc
- oligosaccharides: a short chain of monosaccharides linked via glycosidic bond
- polysaccharides: monosaccharide polymers with 20 to 1000 or more units. eg starch, cellulose, glycogen etc.
