Notably, FTIR spectra of AA-CDs revealed a distinct C = O stretching vibration at 1700 cm and AA-CDs exhibited a new absorption peak at 259 nm, suggesting a possible red shift due to unsaturated carbonyl group formation [43]

The 1.9 resolution crystal structure of the PSII monomer (Figure 5) showed it comprises 17 integral membrane protein subunits (large and low molecular mass) and three extrinsic protein subunits on the luminal side (Umena et al., 2011)
normalising each to its own native-GIP control brings the ratio to about 10, so the honest range is 1016 see ref
