Transport of energy source- sucrose (plants), lactose (milk) Cell surface signals- cell communication and cell-cell recognition. An organ is identified as belonging to the body by carbohydrates. Glucose- present in starch, cellulose and glycogen. Galactose- present in cartilage (cartilage is found in fish and part of the human body) The carbonyl group that serves as one of the monosaccharide"s distinguishing features can be found either at the end of the molecule, forming an aldehyde sugar (aldose), or within the carbon chain, forming a ketone sugar (ketose). The presence of the carbonyl group along with multiple hydroxyl groups provides an array of functional groups in sugars. Galactose are both 6-carbon sugars that only differ by their variation in the spatial orientation of their hydroxyl groups (however, they are not mirror images). 5. 3 sugars exist in linear and ring forms spontaneously bend into one of two ring structures, called the alpha and beta forms of glucose.
