  • Process for sulphation and phosphorylation of proteins and peptides
    Patent number: 4705845
    Abstract: A process for sulphation and phosphorylation of a protein or peptide comprising contacting said protein or peptide with sulphuric or phosphoric acid in the presence of a non-aqeuous apolar organic solvent and contacting the resultant solution with a dehydrating agent is disclosed. Non-aggregating insulin products with bioactivity may be prepared by this process.
    Type: Grant
    Filed: September 5, 1986
    Date of Patent: November 10, 1987
    Assignee: Rockefeller University
    Inventors: Anthony Cerami, Sandor Pongor, Michael Brownlee

  • Method of modifying the conformation of food and feed proteins
    Patent number: 4391839
    Abstract: The invention relates to a method for modifying the conformation of plant proteins for increasing their biological utilization, which comprises treating said plant protein with gaseous hydrogen chloride to adjust its pH to a value between 1.6 and 2.4, as measured in a 20% by weight aqueous suspension, for a period sufficient to increase the digestibility of said protein without bringing the protein into solution or suspension, and thereafter bringing the pH of said protein to a value between 4 and 7 with an alkalizing agent, wherein the moisture content of said protein is increased with the alkalizing agent at most to 50% by weight.
