    Notes: [Auszug] Brain microsomes from normal rats and those deficient in essential fatty acids4 were prepared by scaling down the method of Hokin and Hokin5 so that the microsomes from one rat were suspended in 1 ml. of 0-25 M sucrose. Duplicate incubations were carried out using 0-2 ml. aliquots of microsomes ...

    Notes: [Auszug] Rat liver lipids, after N-2 : 4-dinitrophenylation and methylation as described by Collins and Wheel-don5, were separated into polar and non-polar fractions by counter-current distribution in 85 per cent (v/v) aqueous ethanol-light petroleum. The non-polar fraction was further fractionated by ...

    Notes: [Auszug] SINCE the first use of phosphorus-32 in 1937 l for the study of phospholipid metabolism an immense amount of work has been done using this isotope; but in every case the results have been limited by the analytical methods used to separate the very complicated mixture of naturally occurring ...

    Notes: [Auszug] In a typical experiment a rat was injected intravenously with 0-8 me. of phosphorus-32 (as NaH3aPO4) one hour before being killed. The fat was extracted from the liver and washed with 0-1 N hydrochloric acid to remove cations and contaminating phosphorus-32. The fat (100-300 mgm.) was treated in ...

    Pure All-trans Vitamin A Acetate and the Assessment of Vitamin A Potency by Spectrophotometry (1951)

    Notes: [Auszug] The absorption spectra of many organic solutes vary to some extent in different solvents, even when there is no evidence of equilibria between isomeric forms. In the case of vitamin A such variations have been known to occur since 19352; but they are second-order effects which have hitherto been ...

    Notes: [Auszug] DARTNALL'S report1 of the discovery of two new retinal pigments does not seem to us to rest on convincing evidence. Hartridge2, writing from the same Institute, carries so far what we believe to be fallacious reasoning that the matter requires to be discussed. The statement is made that "the ...

    Notes: [Auszug] Assuming that the compounds formed in the re-action are unsymmetrical ions, 〉max should be a linear function of the number of conjugated double bonds2. In the colour test, anhydrovitamin Ax (with six con-jugated double bonds) has Xmax = 623 mpi3, whereas anhydrovitamin A2 (with probably seven ...

    Notes: [Auszug] In the course of the examination of phospholipid derivatives, an investigation was made of the incorporation of phosphorus-32 into the phospholipids of liver homogenates under conditions that resulted in minimal exchange with the major phospholipids. Rat liver (10 g) was homogenized in 10 volumes ...

    Notes: [Auszug] MUCH is now known12 concerning the biochemistry of scotopic vision; but the chemical nature of the chromophore of rhodopsin (visual purple) is still obscure. When rhodopsin is exposed to light, various changes can be detected. Wald3 showed that a substance, which he called retinene, could be ...

    Notes: [Auszug] WEALE1 in his recent communication has tried to derive the molecular weight of rhodopsin (visual purple) by using Houston's equation. There are several comments we feel should be made. This relationship (like more recent ones based on quantum mechanics) connects the ...
