The sugar component of Golden syrup, Treacle and Molasses is the disaccharide Sucrose. 

The values for Energy (kJ), Carbohydrate and sugar content were obtained from the nutritional information panel on the product purchased. Some of the values however appear to be incorrect. For example Palm sugar has been given an energy value of 1260 kJ/100g and contains 95.2 g of sugar/100g. Each gram of sugar contains 17 kJ. Multiplying 95.2 (the number of grams of sugar in Palm sugar) by 17 kJ gives us a value of 1618.4 kJ, this appears to be a more realistic number.

# The GI of Rice Malt syrup has been rumoured to be relatively low (various sites on the web). However the GI of maltose is 105, greater than that of glucose. Nearly half of the Rice Malt syrup is maltose and presumably has a corespondingly high GI. The other half of the syrup is maltotriose. During digestion maltotriose breaks down to maltose and glucose and then finally into 3 glucose units.
