THE problem of the biosynthesis of ovalbumin is interesting since this protein seems to be synthesized from a non-homogeneous pool of intermediary peptides1–3. We have studied the biosynthesis of this protein in vivo by the laying hen using L-cystine-35S and Na2 14CO3. Selected birds were given these labelled substances and blood was obtained at stated

Abstract A study of the carbohydrate component of ovalbumin points to the presence of three moles of d -glucosamine and six moles of d -mannose per 45,000 g. of the protein. Ovalbumin is extensively oxidized by sodium periodate, the primary reaction with the carbohydrate moiety cleaving three residues of d -mannose and one residue of d ...

A Raman difference spectroscopic investigation of ovalbumin and S‐ovalbumin
Biopolymers, 1979AbstractRaman spectra from 800 to 1850 cm−1 of aqueous solutions of ovalbumin and its more heat‐stable form, S‐ovalbumin, are presented. A Raman difference spectrum (ovalbumin minus S‐ovalbumin) shows differences in intensity in the amide I and III regions. These intensity differences lead us to postulate that the conversion of ovalbumin to S‐ovalbumin

Role of the Intrachain Disulfide Bond of Ovalbumin during Conversion into S-Ovalbumin
Bioscience, Biotechnology, and Biochemistry, 1996Disulfide-reduced and carboxymethylated ovalbumin was treated at pH 9.9 and 55 degrees C for 24 h as a specific condition for preparation of S-ovalbumin. The stability and conformation of the product were investigated. Such alkaline treatment converted native protein to S-ovalbumin, but this modified ovalbumin was not stabilized, according to results ...

Structure and properties of ovalbumin
Journal of Chromatography B: Biomedical Sciences and Applications, 2001Ovalbumin is a protein of unknown function found in large quantities in avian egg-white. Surprisingly, ovalbumin belongs to the serpin family although it lacks any protease inhibitory activity. We review here what is known about the amino acid sequence, post-translational modifications and tertiary structure of ovalbumin.

The sulfhydryl groups of ovalbumin
Archives of Biochemistry and Biophysics, 1951Abstract 1. 1. The reactivity of the sulfhydryl groups of ovalbumin has been investigated by iodine oxidation studies and by a titrimetric method with p-chloromercuribenzoate. The titrimetric method involved the addition of p-chloromercuribenzoate to solutions of the protein buffered at pH 5.3 and back titration of the excess or unreacted mercury

Analytical pyrolysis of ovalbumin
Journal of Analytical and Applied Pyrolysis, 2018Abstract In this study the thermal degradation of ovalbumin (OVA) under nitrogen atmosphere was investigated. For this scope, a multi instrumental approach based on thermogravimetry (TG), thermogravimetry coupled with infrared spectroscopy (TG/FTIR) and pyrolysis coupled with mass spectrometric detection, i.e.

Reduction of allergenicity of irradiated ovalbumin in ovalbumin-allergic mice
Radiation Physics and Chemistry, 2007Abstract Egg allergy is one of the most serious of the immediate hypersensitivity reactions to foods. Such an allergic disorder is mediated by IgE antibodies stimulated by T-helper type 2 (Th2) lymphocytes. This study was undertaken to evaluate changes of allergenicity and cytokine profiles by exposure of irradiated ovalbumin (OVA), a major allergen ...

Interaction between tangeretin and ovalbumin to reduce the allergic effects of ovalbumin
Chemical Research in Chinese Universities, 2016Food allergy has become a worldwide problem. To find an effective way to reduce the allergic effect of allergen is an interesting topic. In this work, the interaction between ovalbumin(OVA) and tangeretin was studied by means of spectroscopy, molecular docking calculation and animal experiment.

Ovalbumin mRNA and Ovalbumin DNA and the Molecular Biology of Steroid Hormone Action [PDF]
, 1975 Certain steroid hormones, including estrogens, progesterone, and testosterone have profound effects on the development and function of the hen oviduct (Oka and Schimke, 1969a, b; O’Malley et al., 1969; Palmiter and Wrenn, 1971; Cox and Sauermein, 1970).
