The Lys and Hyp hydroxylation degree (%Hyl and %Hyp) analysed
in the total connective tissue were significantly greater in
the FP group, indicating a greater stabilisation of the FP collagen
by hydrogen bonds compared with the WP group. However, when
calculating imino acid content as g/100 muscle tissue, the connective
tissue of the WP group had a significantly greater content of
Pro (36%), Hyp (29%) and Hyl (29%) because of the 0.9% units
greater connective tissue yield compared with the FP group
(Fig. 2). The g/100 g Lys content was 88% greater for the WP group
compared with the FP group.
