Fig. 12.5 DV Chl b
ascertained by fast atom mass spectroscopic (Brereton et al. 1983 ), and 1 HNMR
analysis (Wu and Rebeiz 1985 ). It accumulates to the extent of about 100 nmoles per
gram fresh weight of Nec 2 leaves (Rebeiz, Unpublished) (Fig. 12.5 ).
DV Chl b also accumulates in the prochlorophyte picoplankton of the subtropi-
cal waters of the North Atlantic as well as in the picoplankton of the euphotic zone
of the world tropical and temperate oceans, and the Mediterranean sea, where DV
Chl a and b are the predominant Chl species (Chisholm et al. 1990 , 1992 ; Goerike
and Repeta 1992 ; Veldhuis and Kraay 1990 ).
