Enrichment

	Total (N = 25)
Plasma palmitate enrichment, MPE	0.24 ± 0.13
Hepatic NEFA palmitate enrichment relative to plasma	0.09 ± 0.04
Hepatic TG palmitate enrichment relative to plasma	0.30 ± 0.39
Hepatic palmitoyl-carnitine enrichment relative to plasma	0.12 ± 0.8
16/16 DG enrichment relative to plasma	0.29 ± 0.38
16/18:1 DG enrichment relative to plasma	0.27 ± 0.28
16:0 Ceramide enrichment relative to plasma	0.14 ± 0.9
16:0 Sphingoid base enrichment relative to plasma	0.16 ± 0.10

Data are represented as mean ± SD. The plasma palmitate enrichment data include the first 6 studies with a [U-¹³C]palmitate infusion rate of 2 nmol·kg of fat-free mass⁻¹·min⁻¹ and the last 19 studies with an infusion rate of 8 nmol·kg of fat-free mass⁻¹·min⁻¹.

Abbreviations: MPE, molar percent excess; NEFA, nonesterified fatty acid.
