Caption: Polarised light micrograph of crystals from a recrystallization of melted citric acid, now known as tricarboxylic acid. Citric acid may be obtained from natural products such as the juices of citric fruits eg. lemons, or from fermentation of glucose. This fermentation process is an important part in the utilization of glucose to provide energy in metabolism. The series of reactions involved is termed the Citric acid cycle. Magnification: x5 (35mm size).
