a: Peptide ~
b: necklace made of coloured beads

What: "Peptides are like necklaces made of coloured beads - 20 or so types, each being a different amino acid. These can be structured into strings of up to 50. So you can have an almost infinite number of peptides - including insulin and leptin."

a: Polypeptide ~
b: a strand of yarn

What: "One way to think of this relationship is that a polypeptide is like a strand of yarn with no discernible shape. A protein is like a sweater--the polypeptide yarns are woven together in a specific way, thus gaining shape and function in the creation of the sweater."

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.
