Calculated percentage of plasma VA derived from CM retinyl ester and plasma retinol that goes to different tissues in neonatal rats
| Plasma VA | Tissue | Percentage | |
| Oil | VARA | ||
| Plasma retinyl ester in CM/CM remnant | Liver | 52.3% | 22.1% |
| Carcass | 40.3% | 42.7% | |
| Intestine | 4.68% | 31.8% | |
| Kidney | 1.49% | 0.13% | |
| Lung | 1.24% | 3.17% | |
| Plasma retinol | Liver | 75.6% | 56.2% |
| Carcass | 12.8% | 15.3% | |
| Intestine | 4.77% | 20.5% | |
| Kidney | 3.27% | 6.34% | |
| Stomach | 3.12% | 1.37% | |
| Lung | 0.46% | 0.30% | |
The data are the percentages of plasma retinyl esters in CM/CM remnant and of plasma retinol, considered holo-RBP, that goes to different tissues, which were calculated from L(I,10)s and L(I,1)s (shown in Table 1) of the forcing function model (model 1). For example, L(12,10)/[L(12,10) + L(13,10) + L(25,10) + L(15,10) + L(16,10) + L(17,10)] × 100% is the percentage of plasma retinyl ester that is cleared by liver, and L(2,1)/[L(2,1) + L(3,1) + L(4,1) + L(5,1) + L(6,1) + L(7,1)] × 100% is the percentage of plasma retinol turnover that goes to liver.
