Effects of ultrasonic pretreatment on the structure and functionality of chicken bone protein prepared by enzymatic method.

Food Chemistry, 2019
This study investigated the application of ultrasonic pretreatment (UP) to assist with enzymatic extraction of chicken bone protein. Relevant parameters of UP including ultrasonic power, duration of treatment and temperature were studied.

Effects of pretreatments on the structure and functional properties of okara protein

Food Hydrocolloids, 2019
Different pretreatments (homogenization, ultrasonic and steam-cooking treatments) before an alkaline extraction were employed to extract okara protein (OP) from defatted okara (residue left after extraction of the soy oil and water extractable fraction ...

Protein denaturation and tertiary structure

Journal of Chemical Education, 1986
Students may dutifully learn the concepts of protein structure, but meaning is often abstracted due to the lack of opportunity for observing the physical entity. To bridge this gap, an inexpensive denaturation experiment is designed to demonstrate the presence of tertiary structure.

Describing patterns of protein tertiary structure

1985
Publisher Summary This chapter discusses the four major categories of tertiary structure within which subtypes that are more specific described: (1) antiparallel a, (2) parallel α/β, (3) antiparallel β, and (4) small irregular proteins. Within this first major category, the simplest type of structure is the up-and-down helix bundle: an approximate ...

Tertiary Structure Is a Principal Determinant to Protein Deamidation

Science, 1988
The protein deamidation process involves the conversion of the amide side-chain moieties of asparagine and glutamine residues to carboxyl groups. This conversion is an unusual form of protein modification in that it requires catalysis by an intramolecular reaction where both the substrate (asparagine and glutamine side chains) and "catalytic site" (the

Correlation of sequence and tertiary structure in globular proteins

Biopolymers, 1977
AbstractThe x‐ray crystal structures of 19 selected proteins are examined empirically for correlations between the amino acid sequence and long‐range, tertiary conformation. There is clear evidence for preferential associations of certain types of amino acids, particularly among the hydrophobic aliphatic, aromatic, and cysteine residues.

Protein Tertiary Structure Prediction

2006
One of the most important scientific achievements of the twentieth century was the discovery of the DNA double helical structure by Watson and Crick in 1953. Strictly speaking, the work was the result of a three-dimensional modeling conducted partly based on data obtained from x-ray diffraction of DNA and partly based on chemical bonding information ...

Comment on ‘‘Fractal study of tertiary structure of proteins’’

Physical Review E, 1994
It is shown that the mean fractal dimension of the global structure of 90 proteins is greater than that of an unrestricted random walk. Some modifications on the method of calculating the length of the backbone of a protein chain and a possible connection of the mean fractal dimensions of the local structures with the secondary structures of proteins ...
