pectin

/ pĕktĭn /

  1. Any of a group of carbohydrate substances found in the cell walls of plants and in the tissue between certain plant cells. Pectin is produced by the ripening of fruit and helps the ripe fruit remain firm. As the fruit overripens, the pectin breaks down into simple sugars (monosaccharides) and the fruit loses its shape and becomes soft. Pectins can be made to form gels, and are used in certain medicines and cosmetics and in making jellies.
