Calcium soaps of long-chain fatty acids are often referred to as being insoluble. These soaps make up most of the fecal lipid in infants fed high calcium diets and are responsible for increased fat malabsorption in patients with exocrine pancreatic insufficiency receiving enzymes and calcium carbonate antacids. We investigated the solubility of the calcium soaps of long-chain fatty acids in simulated human intestinal contents. Calcium soaps of the [14C]fatty acids of lauric (12∶0), palmitic (16…

Development of an Assay to Determine the Amount of Ca-Fatty Acid Soaps in Feces.
TLDR
The method is suitable for determining fatty acids in the form of Ca-fatty acid soaps in feces and shows consistent and high recovery of fatty acid-soaps.
Effect of excess dietary calcium on colon mucosal membranes and fecal lipids
TLDR
Results indicate that excess dietary calcium resulted in alteration in the density of 4 protein bands of colon apical membranes upon examination on SDS-gel electrophoresis, which may be due to either the reduction of fecal water bile acids and free fatty acids or a direct effect of dietary calcium on membrane proteins.
Influence of dairy matrices on nutrient release in a simulated gastrointestinal environment.
Fortification of Foods with Omega-3 Polyunsaturated Fatty Acids
TLDR
Identification of the causative compounds to reduce and eventually eliminate fishy flavor is important for consumer acceptance of PUFA-fortified foods.
Calcium hydroxy palmitate: possible precursor phase in calcium precipitation by palmitate.
Antioxidant activity and nutrient release from polyphenol-enriched cheese in a simulated gastrointestinal environment.
TLDR
It is suggested that cheese is an effective matrix for the controlled release of nutrients and for the protection of green tea polyphenol integrity and biological activity in the gastrointestinal environment.
Structural and biochemical factors affecting the digestion of protein-stabilized emulsions
Divalent minerals decrease micellarization and uptake of carotenoids and digestion products into Caco-2 cells.
TLDR
Both micellarization and uptake were significantly inhibited by minerals in a concentration-dependent manner, with stronger effects for Fe and Zn compared to Ca and Mg.

Significance of Ca-soap formation for calcium absorption in the rat.
TLDR
The results suggest that, although calcium soap formation may markedly depress calcium absorption in the rat, no significant soap formation takes place when fats are given in the form of triglycerides.
Differences in the intestinal absorption of saturated and unsaturated long chain fatty acids.
Characterization of newborn fecal lipid.
TLDR
The presence of fecal monoglyceride raises the possibility that lipid micellization and/or mucosal transport is insufficient for optimal lipid absorption in full-term newborn infants, and establishes that lipolysis is defective in newborn infants.

Calcium-fatty acid absorption in term infants fed human milk and prepared formulas simulating human milk.
TLDR
In full-term infants 4 to 10 days of age fed human milk or formulas of higher fat and calcium content, the absorption and retention of nitrogen and phosphorus are equal and there is a correlation between calcium and palmitic and stearic acid in the stools.

TLDR
Intraduodenal lipase activity following test meals was found to be a poor predictor of the effectiveness of antacid therapy in improving the efficacy of supplemental enzymes.
STUDIES OF INFANT FEEDING. X.: THE DIGESTION AND ABSORPTION OF FATS. I. CALCIUM IN ITS RELATION TO THE ABSORPTION OF FATTY ACIDS
TLDR
Many cases of so-called "infantile atrophy" and most cases of "fat intolerance" apparently show abnormalities with respect to fat metabolism and their general condition can be improved by withholding fats to some extent.
Fat absorption in infants of birth weight less than 1,300 gm.
Watching fat digestion.
TLDR
During fat digestion a number of physicochemical events can be seen directly by light microscopy, including hydrolysis of emulsified fat droplets by human pancreatic lipase and the sequential formation of two visible product phases.
The immature intestine: implications for nutrition of the neonate.
TLDR
The survival and prognosis of the prematurely born human infant are dependent on a successful transition from the intrauterine to the extrauterine environment, but the gastrointestinal tract of the premature infant and to some extent, of the full-term infant, may be unprepared to provide the requisite absorptive function.
