Product Information
| Description: | Hydroxy-pheophytin a is a primary degradation and oxidation product of Chlorophyll a. The central magnesium ion (Mg2+) is lost and replaced by two hydrogen atoms (forming the pheophytin core). It is typically formed via the allomerization (oxidation) of chlorophyll or pheophytin during plant senescence, fruit ripening, or processing. Rather than acting as a functional photosynthetic pigment, it serves as a biomarker for monitoring the oxidative stress and degradation pathways of chlorophyll in natural or food systems. |
| Stability and Solubility Advice: | Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide. We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details. |
