The concentration of glucose is affected by factors such as eating and exercise, and must be brought back to the normal level of about 4mmol/L to 5.5mmol/L.... Continue Reading →

Polysaccharides – Biological Molecules Ep 8

Last week we looked at glucose and disaccharides, which are simple carbohydrates. However, many carbohydrate molecules are made up of long chains of monosaccharides joined together to form polysaccharides. Today we will look at polysaccharides made from glucose. We saw in the last article that to form the disaccharide maltose, two glucose molecules are joined... Continue Reading →
