Pigment

submitted by: schulzbu
The video is based on an experiment of a Plant physiology course (HORT301) for Horticulture and Biology students. It is a student production geared towards middle school, highschool students and undergraduates as well as viewers who are interested in plant science. It depicts how flower pigments are analyzed using thin layer chromatography (TLC) and spectrophotometry. Investigations that shed light on the chemical and physical behavior of flower pigments are also shown as the isolated...

L-DOPA Is an Endogenous Ligand for OA1

submitted by: medtv
Albinism is a genetic defect characterized by a loss of pigmentation. The neurosensory retina, which is not pigmented, exhibits pathologic changes secondary to the loss of pigmentation in the retina pigment epithelium (RPE). How the loss of pigmentation in the RPE causes developmental defects in the adjacent neurosensory retina has not been determined, but offers a unique opportunity to investigate the interactions between these two important tissues. One of the genes that causes albinism...
