protein structure via hydrogen bonding?...
Since the secondary structure of a protein results from hydrogen bonding between components shared by all amino acids
Distinguish between the different levels of protein structure, including primary, secondary, tertiary, and quaternary Question Is the following statement true? If not, explain why not: Since the secondary structure of a protein results from hydrogen bonding between components shared by all amino acids (a hydrogen on an amide N on one amino acid interacts with an oxygen on the carbonyl of another amino acid), the secondary structure does not depend on the specific amino acid groups (the R-groups) in the amino acid chain. Select...

Protein Structure A protein contains a string of amino acids (usually more than 50) that has a biological function. 15ecause proteins are so large, their structure has several levels, all of which are important for the proper functioning of the protein. Ultimately, the sequence of amino acids (ordering of polar and nonpolar amino acids) dictates the 3-dimensional shape of a protein and this dictates its primary function. Level 1: Primary (1") The amino acid sequence of a polypeptide Protein Backbone...
