Natural enzymes are usually stereospecific sugar molecules made by enzymes of photosynthesis tend to be in certain isomeric form. Sugars also switch between linear (open) structures and ring (closed) structures: from spontaneous, non-enzymatic reactions, when new chiral carbon is formed this way, it may form stereoisomers. Monosaccharides are simplest forms of cho molecules: 6-c chains (hexoses) for glucose, 5-c (pentoses) for rna, 3-c (trioses) for metabolism. Disaccharides form through glycosidic links between 2 monosaccharides. Includes natural sugars like sucrose and lactose; maltose as well. Oligosaccharides: short chains of monosaccharides; about 3-9.
