Toxicity studies with δ-aminolaevulinic acid

Enzymatic synthesis of structured lipids: Transesterification of triolein and caprylic acid ethyl ester

“…A physical mixture of MCT and LCT can meet both nutritional and energy requirements. However, structured lipids (SL) with modified absorption rate have emerged as a preferred alternative to physical mixture (2). SL are synthesized chemically by hydrolysis and random esterification of the mixture of LCT and MCT (1,2).…”

Exposure of Humans to Lead

“…The concentrations of ALA in tissues and body fluids were not determined. The same was true of one study of chronic ALA toxicity in which no toxic effects were noted (98). In one in vitro study it was demonstrated that ALA has an inhibitory effect on erythrocyte and brain Na+ IK+-ATPase with effects being noted within the range of blood serum ALA concentrations associated with acute neurological manifesta tions of porphyria (99).…”

Improved lipase‐catalyzed incorporation of long‐chain fatty acids into medium‐chain triglycerides assisted by supercritical carbon dioxide extraction

“…Therefore, medium-chain fatty acids liberated from MCT are expected to be preferentially dissolved in the SC-CO2 phase because the solubility of medium-chain fatty acids in SC-CQ is much higher than those of long-chain fatty acids and TG. Thus, the reaction equilibrium of MCT + long-chain fatty acids ~-TG containing long-chain fatty acids + medium-chain fatty acids [1] will be shifted in the direction of the introduction of long-chain fatty acids into TG. The equilibrium of this reaction will be further displaced by the continuous SC-CO2 extraction to improve efficiency.…”

“…Physical and rheological properties as well as nutritional values of triglycerides (3~-) ate based not only on the fatty acid composition but also on the positional distribution of the acyl groups bonded to glycerol TG with specific physical properties are required for each use such as in bakery and confectionery goods. The structure of TG affects absorbability (1,2) and nutritional consequences (3,4). Therefor~ the synthesis of structural TG will be important in the future Currently, medium-chain triglycerides (MCT) with one of their acyl groups substituted with a long-chain fatty acid are noted for their unique physiological activity.…”
