First steps tutorial Our first steps tour and our frequently asked questions will help you a lot after registration. They explain how to customize the interface (for example the language), how to upload files and our basic licensing policy (Wikimedia Commons only accepts free content). You don't need technical skills in order to contribute here. Be bold when contributing and assume good faith when interacting with others. This is a wiki. Getting help More information is available at the community portal. You may ask questions at the help desk, village pump or on IRC channel #wikimedia-commons (webchat). You can also contact an administrator on their talk page. If you have a specific copyright question, ask at the copyright village pump.

Goodies, tips, and tricks Put Babel boxes on your user page so others know what languages you can speak and indicate your graphic abilities. You can find the files you have uploaded in your Uploads. Please sign your name on Talk pages by typing ~~~~. To link to an image page without embedding the image, type: [[:File:Foo.jpg]], which produces: File:Foo.jpg. You may enable gadgets (custom features) for your account. There are several tools to upload files. Have you edited Wikipedia before? This guide might be useful. Made a mistake? Do you want to have a file renamed or moved? Use the move link and wait for an authorized user to rename it. Do you want to have your recently uploaded picture removed? Tag it as {{speedy|reason here}}. For more information read the deletion guidelines.

Tip: Categorizing images

---

Hello, Dancojocari!

Tip: Add categories to your files

Thanks a lot for contributing to the Wikimedia Commons! Here's a tip to make your uploads more useful: Why not add some categories to describe them? This will help more people to find and use them.

Here's how:

1) If you're using the UploadWizard, you can add categories to each file when you describe it. Just click "more options" for the file and add the categories which make sense:

2) You can also pick the file from your list of uploads, edit the file description page, and manually add the category code at the end of the page.

[[Category:Category name]]

For example, if you are uploading a diagram showing the orbits of comets, you add the following code:

[[Category:Astronomical diagrams]]

[[Category:Comets]]

This will make the diagram show up in the categories "Astronomical diagrams" and "Comets".

When picking categories, try to choose a specific category ("Astronomical diagrams") over a generic one ("Illustrations").

Thanks again for your uploads! More information about categorization can be found in Commons:Categories, and don't hesitate to leave a note on the help desk.

Amino acids

Your image File:Aa.svg has Iso as the isoleucine abbreviation, this should be Ile. TimVickers (talk) 20:56, 4 February 2010 (UTC)

Typo in File:Aa.svg

en:Talk:Amino acid#Typo in Aa.svg notes spelling mistake in "A." title-line. DMacks (talk) 15:45, 14 January 2011 (UTC)

Thanks for the fix! But you re-introduced a different spelling error: Tyr became Try. DMacks (talk) 15:06, 28 January 2011 (UTC)

Threonine 4th carbon

    I am no chemist, I don't see the 4th carbon in Threonine in your chart of 21 amino acids (Wikipedia 'Amino Acid'). In the Threonine article there is an H3C at the end of the three carbon string, but it's blank in your figure. (Don Fulton)

The CH3 is implied by the line. It is optional to include it, and by convention, it is left out. It should only ever be included where all ends are explicitly labelled for clarity (not in this case)

A message to OTRS suggests that "The amino acid Tyrosine is in the wrong category. It is placed in the non-polar grouping, when in fact it is a polar and uncharged molecule" in your (wonderful!) table. I am completely unqualified to make any assumptions here, so I'll just ask you to look into it and move it if that indeed is the case. Asav (talk) 16:43, 23 October 2011 (UTC) (Wikimedia OTRS Team)

Yes, tyrosine is in fact a polar side group and needs to be placed into the correct group in the chart. (Matt Miles)

Thank you for your comments however, Tyrosine is hydrophobic and therefore is in the correct category. Here is another amino acid categorization for your reference: http://www.sigmaaldrich.com/life-science/metabolomics/learning-center/amino-acid-reference-chart.html

Hi, I really love your vector graphics and I appreciate your work very much. I noticed that you placed histidine into the "positively charged" category, which I think it's perfectly correct, so can you protonate it with just a few seconds of work so as to match its category? Thanks a lot for your work once again! LHcheM (talk) 10:28, 21 September 2012 (UTC)

Thanks! Regarding your question, Histidine is not charged under physiological pH 7.4. It is in that category because it can become protonated at more basic pH or in an enzyme active site for instance.

Periodic table

Hi Dancojocari, the category for the periodic table is Category:Periodic table, not at all Category:Periodic table, science, elements. Please read Commons:Categories to learn how to categorize! -- Ies (talk) 16:43, 2 August 2014 (UTC)

Free Radical Toxicity.svg

I found that File:Free Radical Toxicity.svg was created with converting text to path. Words converted to paths are harder to translate, since one has to change or remove the paths to show the wanted text. Alfa-ketosav (talk) 09:04, 15 September 2023 (UTC)
