extraction and acetylation of purified trypsin from bovin pancreas and study of some its physico-chemical properties

آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...

Proteins Separation and Purification Methods with Focus on Chromatography: a Review Study

  Before describing the structure and mechanism of action of a protein, it must first be subject to purification procedure. Protein purification is a set of processes in which one or a small number of proteins are purified from a complex compound that may be a complete cell, tissue, or organism. Understanding the functions, structural properties, and interactions of the protein are directly re...

Evaluation of base flow separation methods for determining water extraction (Case study: Gorganroud River Basin)

Chemical Compounds and Extraction Methods of “Maollahm”

BACKGROUND Maollahm or meat juice, a by-product of meat, is a traditional remedy in Persian medicine. This product was used as a nourishment or treatment substance for sick people. According to the ancient Persian medicine, animal meat has more affinity with the human body and the body easily absorbs its nutrition. Therefore, one could resort to maollahm for patients requiring urgent nourishmen...

Study on Baseflow Separation of "Abolabas River” Using ADUKIH and RDF Methods

Objective: Currently, the evaluation of baseflow components have been of a worldwide concern due to the influential role of streamflow (base flow and direct flow)in agriculture, water sources management as well as supplying the potable water. Direct and field measurement of baseflow is not practicable especially in large areas with statistics deficiencies. Also, this would not be economically e...
