• What are the chemical properties for serine?

• References are quite essential for at least some of the claims made here, especially with regard to chemical properties, role in diabetes, etc.

Perhaps you could provide some! Slow Graffiti ( talk) 05:57, 20 November 2007 (UTC) reply

• this article could use some clarification as to what serine and glycine's relation is. in the "occurrence" section it is listed as being synthesized from glycine. then in the "Function -metabolic" section it said to be a precursor for glycine. it seems to imply that both are needed to produce the other. —Preceding unsigned comment added by 128.230.234.178 ( talk) 19:31, 4 September 2010 (UTC) reply

How much serine do humans use each day ? Can the elderly synthesize enough or can they have serine deficiency independent of a protein deficiency ? Can low serine be measured by a blood test ? Rod57 ( talk) 12:13, 27 February 2011 (UTC) reply

I believe the line diagram on the right hand side of the page showing the structure of serine is wrong- it shows serine as having only 2 carbons, not 3. Compare to the adjacent ball and stick model and the line diagrams in the text. — Preceding unsigned comment added by 128.36.116.158 ( talk) 21:58, 22 August 2012 (UTC) reply

The text refers to the L- and D- forms, but one of the diagrams refers to the S- and R- forms. This could do to be clarified. Lavateraguy ( talk) 19:34, 28 October 2013 (UTC) reply

Better yet, an can D-serine have it's own page? It has a very different biological role from L-serine--e.g. at the Glutamate NMDA receptor. — Preceding unsigned comment added by 169.230.26.146 ( talk) 14:22, 13 January 2015 (UTC) reply

Why is the term "L-serine" (with "L") mentioned again and again in this article, yet never defined, and it's never explained what the "L" signifies? Please fix. 76.190.213.189 ( talk) 00:44, 20 May 2024 (UTC) reply

This CNN video indicates that L-serine may help prevent cognitive impairment leading to Alzheimer's disease. Should we add information to this article about this?
