Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain phosphorylation and its roles in signalling and metabolism, relate it to disease and drugs at a general level, and support learning and research.

The addition of a phosphate group to a molecule, most importantly to proteins by kinases and reversed by phosphatases, regulating enzyme activity, signalling and cell processes, and to lipids, sugars and nucleotides in metabolism; phosphorylation is central to cell signalling, energy metabolism and disease, and kinases are major drug targets.

What it is for: Biochemistry, cell signalling and pharmacology.

It can be explain phosphorylation chemistry and enzymes; describe roles in signalling and metabolism; relate to disease and kinase inhibitors; find research resources.
