2. Estimation of Amino Nitrogen in Intact Phospholipids by C. H. Lea and D. N. Rhodes
1. Polyacids interact with albumin in salt-free solutions to prevent coagulation of the protein by heat. Polyphosphates (nucleic acids), polysulphates (heparin and dextran sulphate) and polyearboxylates (alginic acid and bacterial polyglutamic acid) were all effective. Effects on optical rotation of the albumin were also demonstrated. 2. The protecting agent acts by preventing the coagulation o...
متن کاملSerum Phospholipids
Serum phospholipid levels were determined in 1,067 healthy persons aged 2 to 77 years. Phospholipid levels increased with age but in a different way for each of the sexes. The age-sex changes of serum phospholipids were similar to those observed for serum cholesterol. Correlation coefficients in members of 156 families indicated that the genetic factor is of importance in determining the serum ...
متن کاملPhospholipids in Mediterranean cephalopods.
Polar lipids of the cephalopods Eledone moschata, Sepia officinalis and Todarodes sagittatus mantle, represent 50.5%, 66.1% and 74.2% of wet tissue respectively. On the other hand the polar lipids of these three species of cephalopods constitute of 80.8%, 94.8% and 93.7% of phospholipids, respectively. The main phospholipids identified were phosphatidylcholine (52.2, 51.3 and 58.4% of total pho...
متن کاملHplc Separation of Phospholipids
The principles involved in the selection of solvents and the use of counter ions, together with the choice of column, for the separation of phospholipids by highperformance liquid chromatography (HPLC) are described.
متن کاملTricomplex Fixation of Phospholipids
A basis for the interpretation of the structure of the cell membrane is often looked for in electron microscope investigations on the structure of lipid models. A difficulty in these investigations is our lack of knowledge of the effect of the preparative treatment on the structure studied. This applies especially to the strongly oxidizing fixatives: osmium tetroxide and potassium permanganate....
