  • Title: New chlorophyll-b forms in a chlorophyll-detergent photosynthetic model system.
    Author: Lehoczki E.
    Journal: Biochim Biophys Acta; 1975 Dec 11; 408(3):223-7. PubMed ID: 1191658.
    Abstract:
    The absorption spectra of chlorophyll b in Triton X-100 micelles at room temperature are superpositions of components with absorption maxima at 640.8, 648.9, 659.5, 669.6, 682.1 and 695.7 nm, obtained from Gaussian analysis of the spectra. The last four forms strongly overlap the chlorophyll a forms of this system obtained with maxima at 659.3, 667.6, 674.3, 680.8, 686.5, 692.8, 701.9, 713.6 and 722.0 nm. Since the in vivo chlorophyll a forms practically coincide with the forms found in this system, the possible existence of in vivo overlapping chlorophyll b and a forms eventually should be taken into consideration. In this case, however, the Gaussian analysis of in vivo absorption bands in itself in the proper spectrum range cannot discriminate between chlorophyll a and b components.
