1.
1. The isolation of fatty aldehydes (as 2,4-dinotrophenylhydrozones) from the bacterial fraction of rumen digesta is described.
2.
2. Mixed rumen bacteria are a rich source of aldehydrogenic lipid as indicated by an aldehyde/phosphorus ration of 0.19 in the non-dialyzable lipid, and the yielding of 2.2. g of aldehyde (calculated as pentadecanal) per 100 g of total bacterial lipid.
3.
3. The major bacterial aldehydes are palmitaldehyde and C15 branched-chain aldehydes.
4.
4. The aldehyde pattern of rumen bacteria is strikingly similar to the aldehyde patterns in certain ruminant lipids suggesting a possible origin of some ruminant aldehydes in the bacteria.

1.
1. The transfer of palmitic acid and sterol between human α-lipoprotein and erythrocytes has been studied.
2.
2. Human erythrocytes take up palmitic acid from α-lipoprotein until all binding sites are filled. The process is very much more rapid if the lipoprotein also extra cholesterol.
3.
3. 38% of the endotenous unesterified sterol of human α-lipoprotein does not exchange with that of rat erythrocytes.
4.
4. [14C]Cholesterol taken up by the lipoprotein after dispersion on Celite exchanges with that of human erythrocytes but it does not behave in exactly the same way as the endogenous sterol.
5.
5. When α-lipoprotein is labelled with both cholesterol and palmitic acid and then incubated with human erythrocytes, each interferes with the transfer, to the cells, of the other.

Phosphatidyl choline (lecithin) fractions were prepared from tuna, salmon, and menhaden muscle, from egg yolk, and from rat and beef liver. Hydrolysis by snake-venom phospholipase A (phosphatide acyl-hydrolase, EC 3.1.1.4) was used to determine the positional distribution of the fatty acids. The fatty acid composition of the hydrolyzed fatty acids (β position) and those remaining with the phosphatidyl moiety (α′ position) were separately determined by gas-liquid chromatography of the methyl esters. 36–86 mole % of the fatty acids esterified in the α′ position were saturated; 91–99 mole % of the fatty acids in the β position were unsaturated. Palmitic and stearic acids were the predominant saturated acids in the α′ position. Some similarity was noted in the β-position distribution of linoleic, arachidonic, eicosapentaenoic, docosaenoic, docosapentaenoic, and docosahexaenoic acids. This observation tends to support the hypothesis of the intechangeability of linoleic and arachidonic acids with “non-essential” polyenoic acids.
