Profiles of the OTP (the local oxygen diffusion-concentration product) obtained at 37°C with phospholipid- (solid symbols) and Chol-analogue spin labels (open symbols) across PCD (solid lines) and CBD (broken lines) for cortical (A) and nuclear (B) lens lipid membranes of eye lenses from human donors of different age groups. Data for age groups 41–60 and 61–70 years are reproduced, respectively, from Reference 42, Copyright 2013, with permission from Elsevier, and from Reference 18, Copyright 2014, with permission from Springer Publishing. The approximate localizations of the nitroxide moieties of spin labels are indicated by arrows. Localizations of the nitroxide moieties of Chol analogue spin labels of ASL and CSL in the PCD and the CBD are explained in Sect. 3.5 of the reference.49 The value of the OTP in the aqueous phase also is shown (dotted lines).
