Description:
An age-related accumulation of D-aspartic acid was detected in the white matter of ten normal brains from individuals aged 30 to 80 years. Gray matter showed no systematic increase in D-aspartic acid. The rate constant for D-aspartate formation in the brain is equal to the predicted value calculated for 37 degrees C. Accumulation of the uncommon D-aspartate isomer in myelinated white matter implies that there is little or no turnover of this tissue, and this may have a bearing on dysfunction of the aging brain or on other diseases of myelin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Man, E H -- Sandhouse, M E -- Burg, J -- Fisher, G H -- New York, N.Y. -- Science. 1983 Jun 24;220(4604):1407-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6857259" target="_blank"〉PubMed〈/a〉
