pectin
"To help retain the apple's structure, I have pre-cooked the apples before placing them in the oven. This allows the pectin to go to work and hold the apple's structure. Pectin is like the mortar that holds the bricks (cellulose) together."
"Pectin is like a large chicken wire net molecule, which has a calcium in the holes. When you eat it, there are enzymes and acids in the stomach but they can't tear the net apart."
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
