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 peroxisomes and their functions, relay biogenesis, specialised forms and disorders from cell biology references in general terms, describe research and clinical significance, and distinguish peroxisomes from lysosomes, mitochondria and other microbodies.

A small membrane-bound organelle found in nearly all eukaryotic cells that contains oxidative enzymes such as catalase and carries out fatty acid oxidation, hydrogen peroxide breakdown and lipid synthesis, with specialised forms such as the glyoxysomes of germinating seeds, the glycosomes of trypanosomes that house glycolysis, and the Woronin bodies and other variants of fungi; peroxisome biogenesis defects cause disorders such as Zellweger syndrome.

What it is for: Not applicable; an organelle.

It can be explain structure and function; relay biogenesis and variants; describe disorders; distinguish related organelles.

Distinguishing features

Catalase and oxidases

Single membrane

Specialised variants

Biogenesis disorders

What it looks like

Not a visible object; small vesicles seen by electron microscopy.

Physical character

diameter: about 0.1-1 micrometres

discovered: 1954 year - Rhodin; named by de Duve 1965

peroxins: about 14 PEX genes in humans count

How it is recognised

Oxidative organelle with catalase

Glyoxysomes, glycosomes, fungal peroxisome variants

Lysosomes digest; mitochondria make ATP; other microbodies differ in enzymes

What the second pass must settle

  • Should glyoxysome and glycosome be separate primary entries?
  • How should cell biology references be linked?
  • The registry entry has merged aliases naming variants and numbered subpopulations; should they be split off?
