Abstract
1. A wide range of intermediary metabolites and substrate analogues have no effect on the oxidation of dl-1-aminopropan-2-ol to aminoacetone by washed-cell suspensions of Escherichia coli. Only dl-2-hydroxy-2-phenylethylamine, dl-1,3-diaminopropan-2-ol, dl-serine and l-1-(3,4-dihydroxyphenyl)-2-aminoethanol act as inhibitors. 2. Dialysed cell-free extracts of E. coli exhibit an NAD(+)-dependent dl-1-aminopropan-2-ol-dehydrogenase activity of approx. 8mmumoles of aminoacetone formed/mg. of protein/min. at the pH optimum of approx. 10. The K(m) values for the coenzyme and dl-amino alcohol are approx. 0.4 and 10.0mm respectively. A smaller peak of activity occurs at pH7.0-7.2, the K(m) for NAD(+) at pH7 being approx. 0.05mm. 3. Enzyme activity in cell-free extracts is inhibited by dl-2-hydroxy-2-phenylethylamine, dl-1-aminopropane-2,3-diol and dl-serine. dl-Phenylserine and dl-1-aminobutan-2-ol are oxidized to compounds reacting as amino ketones. 4. In fresh cell-free extracts l(+)-1-aminopropan-2-ol preparations are oxidized more rapidly than racemic or laevo-rotatory material, the d(-)-enantiomorph appearing to act as a competitive inhibitor. The K(m) for l(+)-1-aminopropan-2-ol appears to be approx. 1.5mm when highly resolved substrate preparations are used, either in the free base form or as the l(+)-tartrate salt. 5. l(+)-1-Aminopropan-2-ol dehydrogenase is a labile enzyme, and in appropriately treated extracts activity towards the d-enantiomorph is detectable and relatively higher than that towards the l-enantiomorph. 6. Optimum activity of l-threonine-dehydrogenase in cell-free extracts is exhibited at pH9.6 in the presence of NAD(+). The K(m) values for coenzyme and amino acid substrate are approx. 0.08 and 5.0mm respectively. This enzyme is distinct from 1-aminopropan-2-ol dehydrogenases on the basis of kinetic evidence, and the separation of activities by gel filtration. 7. Both l-threonine and dl-1-aminopropan-2-ol dehydrogenases are markedly inhibited by 8-hydroxyquinoline and p-chloromercuribenzoate, but only slightly by other chelating and thiol reagents. 8. E. coli is incapable of growth on simple synthetic media, containing a variety of carbon sources, when dl-1-aminopropan-2-ol is supplied as the sole source of nitrogen. It appears unlikely that the micro-organism can deaminate aminoacetone. 9. The metabolic roles of l-threonine dehydrogenase, aminoacetone and 1-aminopropan-2-ol dehydrogenases are discussed.

Abstract
The hydrolysis of endogenous phosphatidyl ethanolamine and lecithin in rat liver mitochondria has been studied by using mitochondria from rats injected with ethanolamine-1,2-(14)C or choline-1,2-(14)C. A phospholipase A-like enzyme has been demonstrated, which catalyzes the hydrolysis of one fatty acid ester linkage in phosphatidyl ethanolamine and lecithin. Phosphatidyl ethanolamine is hydrolyzed in preference to lecithin and the main reaction products are free fatty acids and lysophosphatidyl ethanolamine. The further breakdown of lysophospholipids appears to be limited in mitochondria, which indicates that lysophospholipase activity is mainly located extramitochondrially. The enzymic system is greatly stimulated by calcium ions, and also slightly by magnesium ions, while EDTA inhibits it almost completely. These findings are discussed in relation to previous observations on the effect of calcium and of EDTA on the functions of mitochondria. The possible function of the mitochondrial phospholipase for the formation of phospholipids with special fatty acids at the alpha- and -position is discussed.

Abstract
Ethanolamine is readily metabolized by oat, pea, wheat, apple and carrot tissue preparations. Ethanolamine-1,2 (14)C was incorporated into the lipid fraction, and (14)C activity was distributed in the organic acid, sugar, acid volatile, carbon dioxide and insoluble residue fractions. The distribution varied with the particular tissue. Incorporation into the lipid fraction occurred in tissue homogenates in the absence of ATP by a Ca(++) activated system similar to that reported for animal preparations. The initial step in ethanolamine oxidation involves an amine oxidase. Glycolaldehyde and glyoxylic acid are metabolic intermediates, the former in the conversion of ethanolamine to carbon dioxide. No evidence was obtained for the operation of an ethanolamine transaminase or for the involvement of phosphorylated intermediates in the conversion of ethanolamine to carbon dioxide.

Abstract
1. Washed-cell suspensions of Escherichia coli, incubated at the optimum pH of 6.4 and with a saturating substrate concentration of approx. 10mm, convert dl-1-aminopropan-2-ol into aminoacetone at a rate of approx. 4.0mmumoles/mg. dry wt. of cells/min. at 30 degrees . 2. Mg(2+), Mn(2+), Co(2+), Zn(2+), Ca(2+), K(+) and NH(4) (+), as sulphates, and EDTA have no effect on this rate, although Cu(2+) inhibits and Fe(2+) activates to some extent. 3. Conditions of growth markedly affect the rate of aminoacetone production by cell suspensions. 4. Dialysed cell-free extracts of E. coli exhibit 1-aminopropan-2-ol-dehydrogenase activity, the enzyme having optimum activity at pH7.0, a requirement for NAD(+) and K(+), and a K(m) for the amino alcohol substrate of 0.8mm, calculated for a single enantiomorph. 5. Under optimum conditions 1-aminopropan-2-ol dehydrogenase forms aminoacetone at rate of approx. 3.0mmumoles/mg. of protein/min. at 37 degrees . The enzyme is only slightly inhibited by dl-3-hydroxybutyrate and dl-2-hydroxy-2-phenylethyl-amine. 6. l-Threonine-dehydrogenase activity is exhibited by both whole cells and cell-free extracts. Whole cells produce aminoacetone from l-threonine more slowly than they do from dl-1-aminopropan-2-ol, whereas the situation is reversed in cell-free extracts. Both kinetic evidence, and the fact that synthesis of 1-aminopropan-2-ol dehydrogenase, but not of threonine dehydrogenase, is repressed by compounds such as glucose and pyruvate, provide evidence that the amino alcohol is oxidized by a specific enyme. 7. The metabolic role of 1-aminopropan-2-ol dehydrogenase is discussed.

Abstract
1. An enzyme that hydrolyses sphingomyelin to ceramide (N-acylsphingosine) and phosphorylcholine was isolated from rat liver. 2. The enzyme is particle-bound (mitochondria or lysosomes) and can be solubilized by ultrasonic treatment and freezing and thawing. 3. It has been partially purified by precipitation at pH5.2, neutralization and ammonium sulphate fractionation. 4. The enzyme is activated by Triton X-100 (0.2%) or low concentrations of cetyltrimethylammonium bromide (0.02%), higher concentration being inhibitory. 5. The optimum pH is 5-5.5. 6. Of synthetic substrates tested, the erythro isomers of dl-trans-2-N-palmitoyl-1-O-phosphorylcholinesphingosine or dihydrosphingosine were hydrolysed at a rate similar to the natural compound. The threo isomer was hydrolysed much more slowly. The enzyme had little activity on lecithin. 7. The split products of the hydrolysis have little inhibitory effect.

Abstract
The disturbance in lipid metabolism caused by deficiency of dietary choline in rats was investigated with H3-palmitic acid as a tracer. The incorporation of radioactivity into blood triglycerides, as compared to that in choline-supplemented controls, showed a striking decline in rats taken at intervals during the development of choline deficiency. This was partially corrected by choline re-feeding for 2 days and was normal after 4 days of choline re-feeding. Both the total amounts and the radioactivities of phosphatidyl choline in the liver and total phospholipids in the plasma were reduced in choline deficiency and were restored by choline re-feeding, whereas phosphatidyl ethanolamine in the liver was not affected. The findings confirm that the fatty liver of choline deficiency is the result of an impairment in the transport of triglyceride from the liver, and support the hypothesis that it occurs because of a restriction in the synthesis of phosphatidyl choline which is required for lipoprotein formation.A marked reduction in the transformation of14C-ethanolamine into phosphatidyl choline was evident in choline deficiency, but most of the increase in liver phosphatidyl choline which occurred subsequent to choline re-feeding appeared to be from synthesis by the direct (CDP-choline) pathway.

Abstract
1. The phosphate esters of dimethylaminoethanol and monomethylaminoethanol can be incorporated from their cytidine diphosphate esters into the phospholipids of brain and liver dispersions; the deoxycytidine nucleotides of the same bases are less effective precursors. 2. The cytidylyltransferases of brain and liver are less effective in forming the cytidine diphosphate esters of monomethylaminoethanol and dimethylaminoethanol than those of ethanolamine and choline.

Abstract
Myelin was isolated from cerebral white matter from a patient who had died of metachromatic leukodystrophy, and its lipid composition was analyzed. Although the lipid content was nearly normal, the myelin contained a three- to fourfold excess of cerebroside sulfate and a threefold deficiency of cerebroside compared to normal myelin. The deficiency of cerebroside and the excess of cerebroside sulfate may account for defective myelination in this disease.
