Some factors influencing phosphatidylcholine formation.
Conversion of ethanolamine to choline (l), with methionine serving as the methyl donor (2), has been established in the intact animal. Stetten (1) observed that the labeled nitrogen of ethanolamine-N15 was retained in the choline molecule, and we determined that the carbon chain of ethanolamine is the precursor in vivo of the choline carbon chain (3). Conversion of ethanolamine to choline by in...
متن کاملFactors Influencing Histoplasmin Formation.
Histoplasmin was originally defined by Zarafonetis and Lindberg (1941) as "the antigenic substance or substances of Histoplasma capsulatum" Darling. The term, however, is now used generally to indicate the filtrate derived from the growth of the mycelial phase of Histoplasma in a liquid synthetic medium and capable of producting a positive skin reaction in sensitized animals and man. The histop...
متن کاملSome factors influencing the effect of cholesterol
SYNOPSIS Inhibition of streptolysin 0 activity by cholesterol depends on the latter being in free form. The normal esterified and protein-bound cholesterol fractions in serum do not influence streptolysin 0 activity. However, high cholesterol levels in rabbits fed cholesterol with cholic acid were associated with an increased antistreptolysin 0 effect. It is suggested that this occurs when all ...
متن کاملSome Factors Influencing the Activity of Peroxidase”
An important source and preparation method are reported from the Munich laboratories of WillsGtter (l-3) and his associates who have prepared a highly purified peroxidase from horseradish. The methods of Willstatter, with certain modifications, were employed in the present investigation. About 14 pounds of horseradish roots were cleaned, sliced thin, and self-dialyzed in running water for 8 day...
متن کاملOn Some Factors Influencing MLP Error Surface
Visualization of MLP error surfaces helps to understand the influence of network structure and training data on neural learning dynamics. PCA is used to determine two orthogonal directions that capture almost all variance in the weight space. 3-dimensional plots show many aspects of the original error surfaces.
