These peptides are synthesized by translation of mRNA. They are often subjected to proteolysis to generate the mature form. These function, generally in higher organisms, as hormones and signaling molecules. In general, they are linear in structure.
But wait, there’s more to the story! These peptides don’t just sit around post-synthesis. Once they’ve been synthesized by translation of mRNA, they often find themselves undergoing proteolysis, because apparently, maturity is not just a human concept. This process generates the mature form, allowing them to step into their roles. These function, generally in higher organisms, as the body’s little messengers, acting as hormones and signaling molecules. And, in general, they are linear in structure—because even in the chaotic world of biology, a little order is necessary.
