1. Sodium dodecyl sulfate (SDS) attacks the chlorophyll-protein compound modifying its protein properties and absorption spectrum. 2. In the presence of SDS, chlorophyll is quantitatively converted to phaeophytin; i.e., magnesium is removed from the molecule. This reaction, measured spectrophotometrically, proceeds at a rate directly proportional t...

... NaLS causes blue shifts of 280 nm band (generally observed for each protein and amino acids) owing to conformational changes by disruption of hydrogen bonds. This change in absorption may be due to various reasons 25,29,[36][37][38] like NaLS induced removal of strong chlorophyll-chlorophyll interaction and pheophytinization coupled with conformational changes in the protein part of the chlorophyll complex (Sect. 4 of SI). ...
