Differentiation Between Ripening Stages of Iberian Dry-Cured Ham According to the Free Amino Acids Content [PDF]
In this paper, the differentiation of three ripening stages, postsalting, drying, and cellar, of Iberian dry-cured ham has been carried out according to their free amino acids contents. Eighteen L-amino acids, alanine, 2-aminobutanoic acid, aspartic acid,

Self-interaction chromatography as a tool for optimizing conditions for membrane protein crystallization [PDF]
The second virial coefficient, or B value, is a measurement of how well a protein interacts with itself in solution. These interactions can lead to protein crystallization or precipitation, depending on their strength, with a narrow range of B values ...

Paper Chromatography of Thioureas [PDF]
IN the course of a current investigation, it became necessary to separate and identify minute amounts of N-substituted thioureas. Paper chromatography suggested itself as the method of choice for this purpose, and a technique has now been worked out which gives satisfactory and reproducible results on some thirty thioureas investigated, separately or ...

Detection of phospholipids on paper chromatograms by neutron activation
Improvements in the detection of phospholipids on paper chromatograms by neutron activation (with the formation of P32-compounds) have been made. Formaldehyde-treated papers were subjected to low neutron dosage after chromatographic development and the ...
