Table 2. Fatty acid composition (wt% of total fatty acid) of infrapatellar fat pad ¹.

	Inner tissue	Outer tissue
C16: 0	23.45 ± 1.04	25.10 ± 0.99*
C16: 1	4.32 ± 0.57	3.33 ± 0.40*
C18: 0	9.30 ± 1.86	11.83 ± 1.41
C18: 1	48.46 ± 1.07	47.20 ± 1.61*
C18: 2n-6	8.50 ± 1.08	6.61 ± 1.18*
SAFA	34.95 ± 2.78	39.10 ± 2.03*
MUFA	54.31 ± 1.52	51.86 ± 2.00*
PUFA	9.04 ± 1.96	10.74 ± 1.51
Unsaturation index	78.05 ± 4.97	70.34 ± 3.93*

¹Minor fatty acids accounting for less than 2% of total fatty acid were not included. Values are presented as mean ± SD obtained from eight replicates.

^*Value in the outer tissue is significantly (P < 0.05) different from that in the inner tissue.

SAFA: saturated fatty acids; MUFA: monounsaturated fatty acids;

PUFA: polyunsaturated fatty acids; Unsaturation index is the sum of [number of double bonds for each fatty acid ×% of each fatty acid].
