Sample text

This paradox is usually noted in the context of computational approaches to protein structure prediction. Levinthal, however, suggested that the stable structure could have a higher energy and that protein folding will be accelerated and guided by the rapid formation of local interactions. These then determine the further folding of the peptide, suggesting local amino acid sequences that form stable interactions and serve as nucleation spots in the folding process. 1 Protein Structure Prediction and Determination Around 90% of protein structures available in the Protein Data Bank (PDB) have been determined by x-ray crystallography (Zhang 2008).

Peptides with different amino acid sequences were obtained from soybean protein, after hydrolysis with enzymes and UF. They possessed various biological activities based on the initial protein source, enzyme used, and processing conditions. Different enzymes were used for hydrolyzing the soy protein that yielded peptides with antioxidant peptides (Pena-Ramos and Xiong 2002), peptides with anticancer properties (Kim et al. 2000), or peptides with hypotensive activity (Wu and Ding 2001). Proteases from bacterial cultures were used to hydrolyze milk protein to obtain peptides, which were fractionated by UF and were shown to have significant antioxidant properties (Hogan et al.

The matrix consists of a gel of a specific pore size through which molecules may pass or be retained on the column owing to their molecular sizes. In general, smaller molecules diffuse faster and better into pores than larger molecules, resulting in differential retention times. Parkash, Ng, and Tso (2002) prepared protein hydrolysates from rice bran, employing SEC coupled with HPLC. The molecular fragments ranged between 1 and 150 kDa after hydrolysis with alcalase and flavourzyme. Further, anion-exchange chromatography of the extracted rice bran hydrolysates was performed.
