Phospholipid requirements for the reconstitution of Complex-III vesicles exhibiting respiratory control (electron-transport control) were studied. Vesicles prepared from pure phosphatidylethanolamine gave maximal control ratios. Phosphatidylcholine alone did not support respiratory control, although these vesicles were capable of maintaining stable K+-diffusion gradients. Apparently Complex III cannot insert into a bilayer of phosphatidylcholine. Formation of mixed phosphatidylcholine/phosphatidylethanolamine (6:1, w/w) vesicles was sufficient, however, to allow Complex-III insertion and to restore respiratory control. Mixtures of acidic phospholipids with either phosphatidylethanolamine or phosphatidylcholine did not improve respiratory control over that obtained with pure phosphatidylethanolamine. Phosphatidylethanolamine from bovine heart mitochondria, soya beans or Escherichia coli was equally effective in reconstituting respiratory control, suggesting that the specificity is referable to the head group and not to the fatty-acid moiety.

Fatty acid esters of hydroxy fatty acids (FAHFA), diglycerides (DG) and monoacetyldiglycerides (MAcDG) are gaining interest as functional lipids in pharmaceuticals and functional food formulations for managing and treating metabolic or inflammatory diseases. Herein, we investigated whether the antler and/or meat of two Cervids (moose and caribou) are novel sources of FAHFA, DG and MAcDG. We observed FAHFA present in moose and caribou composed mainly of polyunsaturated families, and that the esterification occurred frequently at the C5-hydroxy fatty acid moiety, most noticeably arachidonic acid 5-hydroxyeicosatrienoic acid (ARA-5-HERA). Moose antler, caribou and moose meat also contained significant levels of both 1,2-DG and 1,3-DG lipids. The 1,3-DG molecular species consisted mainly of 16:0/18:1, 18:0/16:0, and 18:0/18:1. On the other hand, major 1,2-DG species consisted of DG 18:0/18:0, 16:0/16:0 and 18:1/18:1 molecular species with higher levels in the antler compared to the meat. The molecular species composition of MAcDG was very simple and consisted of 14:2/18:2/2:0, 16:0/18:2/2:0, 16:0/18:1/2:0 and 18:0/18:1/2:0 with the first species 14:2/18:2/2:0 predominating in the tip of moose antlers. Increasing access to and knowledge of the presence of these functional lipids in foods will enhance their intake in the diet with potential implications in improving personal and population health.

Palmitic, oleic, and butyric acid esters of cetyl alcohol were fed to mature rats. Cetyl palmitate was quantitatively excreted in the feces and produced no physiologic aberration. While cetyl oleate was 75% absorbable, it was of little value as an energy source and was partially excreted through the skin. Feeding of cetyl butyrate also induced seborrhea. Data on free fatty acids in gastrointestinal contents and on the specificity of seborrheic lipids indicate that cetyl esters are largely absorbed without hydrolysis, if the fatty acid moiety is readily absorbable, and excreted by way of the skin without modification.
