    Monosaccharides can be aldose or ketose 
    sugars depending on the carbon which the carbonyl group is linked to. 
    An anomeric carbon is a carbon joined to 2 oxygen atoms. 
    Glycosidic bonds are formed between two monosaccharides to form a disaccharide through a condensation reaction. 
    Examples of polysaccharides are starch, glycogen and cellulose. Starch and glycogen perform storage functions while cellulose provides structural support. ]]>     2018-03-26 05:43:53 UTC https://padlet.com/WoonKeat/fjmp9fzy5zts/wish/245946891     Ming Xuan 18S7 https://padlet.com/WoonKeat/fjmp9fzy5zts/wish/245946914 Anomeric carbons
