An Investigation into the effects of Concentration upon pectinase and the yield of apple juice it produces. Aim To investigate the effects of concentration upon pectinase and the yield of apple juice it produces. Introduction and Biological Knowledge Pectinase is an enzyme that specifically targets Pectin which bonds the long Cellulose strands together to form the outer core of the apple. Breaking these bonds would allow the cellulose strand to move more freely and therefore form a liquid - in this case apple juice. Pectin is a molecule similar to starch except that the repeating unit of pectin is galacturonic acid instead of glucose as in starch. Galacturonic acid is still very similar to glucose, except one of the carbons has a -COOH group attached instead of a CH2-OH. The pectin chain is held together by a bond between carbon 1 of one galacturonic acid and carbon 4 of the next one and so...
