WebSerine metabolism in plants has been studied mostly in relation to photorespiration where serine is formed from two molecules of glycine. However, two other pathways of serine formation operate in plants and represent the branches of glycolysis diverging at the level of 3-phosphoglyceric acid. WebSerine is a non-essential amino acid that can be either taken up by the cell or synthesized de novo from glycolytic intermediates through the serine synthesis pathway (SSP) (Fig. 8) (Yang & Vousden, 2016).
