Synchrotron FTIR Microspectroscopy Study of the Striatum in 6-Hydroxydopamine Rat Model of Parkinson's Disease

Table 3

The percentage compositions of protein secondary structure in the striatal neurons.

Secondary structure	Control	PD lesioned side	PD unlesioned side
β-sheet	28.8±1.6%	46.2±0.89%** (𝑃=0.001)	39.4±0.81%** (𝑃=0.001)
α-helix	28.5±1.5%	26±0.51% (𝑃=0.004)	25.2±0.61% ** (𝑃=0.004)
Unordered structure	42.6±1.8%	27.8±0.76%** (𝑃=0.001)	35.3±0.81%** (𝑃=0.001)

**Statistically significant differences between control and PD group were marked, the 𝑃 values of Mann-Whitney 𝑈 test were shown in the parenthesis.
