Suggested Edits for Plastoquinone Page
Peer Review (Tianxiao Yang):
- Structurally, it is usually a 2,3-dimethyl-1,4-benzoquinone molecule with a side chain of nine isoprenyl units.
// I would change this sentence. It's a bit awkward.
-It is very structurally similar to ubiquinone, or Coenzyme Q10, differing by the length of the isoprenyl side chain, replacement of the methoxy groups with methyl groups, and removal of the methyl group in the 2 position on the quinone.
// This is a good chance to talk about the synthesis of plastoquinone. Maybe start a new section for this?
-Plastoquinol, the reduced form, also functions as an antioxidant by reducing reactive oxygen species, some produced from the photosynthetic reactions, that could harm the cell membrane.
// You should expand on the mechanisms of this sort of cellular protection.
-It transfers the electrons further down the electron transport chain to plastocynanin through the cytochrome b6f protein complex, which, besides catalyzing the electron transfer, also transports the two protons into the lumen of thylakoid discs.
// Discussion of the chemistry or mechanism of transport would be a great addition.
Overall, very good article contributions. It would be best to just expand some more. I think with the addtion of pictures/diagrams, this could become very good!
Plastoquinone: Peer Review by Tnzhou
Good opening sentence, complete with links to terms. Could mention that the 9 isoprenyl units are used to “anchor” the molecule into the membrane of the chloroplast
Does PQ-3 mean that the side chain has 3 isoprenyl units instead of 9? Could elaborate a little bit on the analogs and how they differ from PQ-9
I would suggest using a different term than “dissolved” to describe how the isoprenyl units are integrated into the lipid bilayer, it feels to me that there could be a more chemically accurate term for this.
Just a question but does plastoquinone tend to “wiggle around” in the membrane or stay in one place? Not an edit, just curious.
In the second paragraph, I would avoid starting off with “It”. I do believe the sentence is a very good addition but could be phrased better. In the second sentence, is “it” referring to plastoquinone? Could specify to avoid confusion.
The sentence “Plastoquinol, the reduced form, also functions as an antioxidant by reducing reactive oxygen species, some produced from the photosynthetic reactions, that could harm the cell membrane.[3]” could be better in the first paragraph. The blurb on the prefix that follows the forementioned sentence would also fit better in the first paragraph.
So far, I really enjoyed reading this article, most of which I can see are your edits and additions. Good work!
An image for the “role in photosynthesis” would greatly benefit the text.
Again, avoid beginning the paragraph with “it”; enhance the clarity of your text by replacing vague pronouns with the term they actually represent.
In the first paragraph for the Role in Photosynthesis section, it would help to briefly explain what the electron transport chain does ( produce ATP using NADPH, etc) to give a more broad overview of how plastoquinone fits into the overall process of photosynthesis.
For the Derivatives section:
Instead of saying just “some derivatives designed”, could say “Some derivatives of plastoquinone are designed” to add clarity. Although this article is about plastoquinone and it is safe to assume that plastoquinone is what the derivatives are belonging to, it would help to reiterate plastoquinone.
The last sentence that is “floating” on its own paragraph could be stuck to the end of the larger body of text.
Overall, great work on the article; it was very interesting to read and contained great content and information that improved my understanding of your topic.
