PPT-Classification of Proteins

By Professor Dr Jamal Ahmed Abdel Barry On the other hand proteins can be classified based on structure into 4 types   1 Primary Structure Prefers the covalent bond peptide bond and S S bond Cysteine Cysteine and the sequence of Amino Acids . Classification based on solubility and composition simple conjugated and derived proteins i Simple proteins only amino acids Albumins salting out glycine Globulins insoluble or sparingly soluble in water methionine Prolamins brPage 2br lysine Glutel Learning objectives. Students should understand the following:. Genetic comparisons can be made between different species by direct examination of their DNA or of the proteins encoded by this DNA.. Comparison of DNA base sequences is used to elucidate relationships between organisms. These comparisons have led to new classification systems in plants.. SUMI SINGH. (sxs5729).

Bacteriophages are the single most abundant biological entity on earth, and influence every environment in which bacteria exist. There are no current algorithms which reliably analyze phage structural protein sequences and predict their function. . Objectives:. Know the basic terminology related to fats and proteins. .
