Absorption, Distribution and Excretion
In the small intestine, most triglycerides are split into monoglycerides, free fatty acids, and glycerol, which are absorbed by the intestinal mucosa. Within the epithelial cells, resynthesized triglycerides collect into globules along with cholesterol and phospholipids and are encased in a protein coat as chylomicrons. Chylomicrons are transported in the lymph to the thoracic duct and eventually to the venous system. The chylomicrons are removed from the blood as they pass through the capillaries of adipose tissue. Fat is stored in adipose cells until it is transported to other tissues as free fatty acids which are used for cellular energy or incorporated into cell membranes. When 14C-labeled long-chain triglycerides are administered intravenously, 25% to 30% of the radiolabel is found in the liver within 30 to 60 minutes, with less than 5% remaining after 24 hours. Lesser amounts of radiolabel are found in the spleen and lungs. After 24 hours, nearly 50% of the radiolabel has been expired in carbon dioxide, with 1% of the carbon label remaining in the brown fat. The concentration of radioactivity in the epididymal fat is less than half that of the brown fat. After absorption, long- chain saturated fatty acids are transported mainly via the intestinal lymph as triglycerides. Fatty acids with 10 or less carbon atoms are transported mainly from the intestine via the portal blood vessels. There are also data indicating that unsaturated long-chain fatty acids are absorbed mainly via the lymph vessels. The skin penetration enhancement of drugs by tricaprylin has been demonstrated in vivo using Wistar rats and in vitro using hairless female mice. ... The drug permeation ratio in the presence of triglycerides increased in the following order: Tricaprylin (C8) > Triolein (CI8) > Tributyrin (C4) > Triacetin (C2). |

| Additional Infomation |
Tricaprylin is an odorless viscous clear colorless to amber-brown liquid. (NTP, 1992)
Trioctanoin is a triglyceride obtained by acylation of the three hydroxy groups of glycerol by octanoic acid. Used as an alternative energy source to glucose for patients with mild to moderate Alzheimer's disease. It has a role as an anticonvulsant and a plant metabolite. It is a triglyceride and an octanoate ester. Tricaprilin has been used in trials studying the supportive care and treatment of Alzheimer's Disease. |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (4.42 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.08 mg/mL (4.42 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
