Encyclopedia: Protein Structure
Proteins are an important class of biological macromolecules present in all biological organisms, made up of such elements as carbon, hydrogen, nitrogen, phosphorus, oxygen, and sulfur. All proteins are polymers of amino acids. The polymers, also known as polypeptides consist of a sequence of 20 different L--amino acids, also referred to as residues. For chains under 40 residues the term peptide is frequently used instead of protein. To be able...

1 what is meant by the term 'secondary structure' when appiled to protein structure? 2 how...
1 and 2) Proteins fold in three dimensions. Protein structure is organized hierarchically from so-called primary structure to quaternary structure. Higher-level structures are motifs and domains. The primary structure is...

Is protein structure or function more amenable to determination using in silico methods? Why? Please...
de novo structure nor function can not be determined in silico. however, that method is very useful for determination of both based on homology to known proteins. for example, if...

What are primary,secondary and tertiary protein structure?
"Primary structure The sequence of the different amino acids is called the primary structure of the peptide or protein. Counting of residues always starts at the N-terminal end (NH2-group), which is the end, where the amino...
