Those with any smattering of biology education will remember that the 22 amino acids that are most important to human biology all have both a 3-letter symbol and a 1-letter symbol, which are well standardized [1] (see them given, for example, at Essential amino acid § Essentiality in humans). Someone recently pointed out in an edit summary that the 1-letter symbols overlap with the chemical element symbols. Yes, that is of course true, but it doesn't mean that biologists don't use the 1-letter symbols or have a movement afoot to stop using them; the key is that they use them within the context of discussions where the meaning is clear, namely, in presenting long protein sequences. [2] Another edit summary pointed out that the symbol F is not an abbreviation. Yes, that is of course true; all 22 of the 1-letter symbols are just that, symbols, not abbreviations, although most of them reflect the initial of the name of the amino acid (which even F does, echoing φ/ ph). Both of those facts are also true of the chemical element symbols. Quercus solaris ( talk) 23:29, 5 March 2018 (UTC)

What's the difference?-- The article doesn't mention it. It just casually starts talking about L-Phenylalanine without mentioning any difference at all, or if there even is one. And all the "L-..." does is redirect here with no explanation.
This is significant, as whenever I'm shopping for the drug, only L-Phenylalanine is mentioned, never Phenylalanine -- so the "L-" version seems like the only one being sold to the public. I'd personally appreciate knowing the difference by reading it in the article, otherwise I won't know what I'm buying. 2600:1002:B00F:C12F:251F:CE4D:D354:3965 ( talk) 10:39, 5 December 2022 (UTC)
