Question

The sequence of amino acids is major factor in which type of protein classification;

Options

A
Primary Proteins
B
Secondary Proteins
C
Tertiary Proteins
D
Both Primary and Tertiary Proteins

Explanation

•Primary structure of protein is the simplest level of protein structure.It comprises the number and sequence of amino acids in a protein molecule.

For Example:Dystrophin has an important primary structure.

•Secondary structure is formed because of hydrogen bonding between amino acids in the peptide chain.

For Example:Alpha helices and beta pleated sheets.

Tertiary structure is maintained by three types of bonds;hydrogen bond,ionic and disulphide(-S-S-).

For Example:Myoglobin

•In quaternary structure,tertiary proteins are held together by hydrophobic interactions,hydrogen and ionic bonds.

For Example:Hemoglobin

•Primary structure of protein is the simplest level of protein structure. It comprises the number and sequence of amino acids in a protein molecule.

For Example, Dystrophin has an important primary structure.

•Secondary structure is formed because of hydrogen bonding between amino acids in the peptide chain.

For Example Alpha helices and beta-pleated sheets.

• Tertiary structure is maintained by three types of bonds; hydrogen bond, ionic, and disulfide (-S-S-).

For Example Myoglobin

•In quaternary structure, tertiary proteins are held together by hydrophobic interactions, hydrogen, and ionic bonds.

For Example Hemoglobin

A secondary structure is formed because of hydrogen bonding between amino acids in the peptide chain, not because of the primary amino acid sequence.

For Example Alpha helices and beta-pleated sheets.

Tertiary structure is maintained by three types of bonds; hydrogen bond, ionic, and disulfide (-S-S-) and not because of the primary amino acid sequence.

For Example Myoglobin

Tertiary structure is maintained by three types of bonds; hydrogen bond, ionic, and disulfide (-S-S-). Only primary protein structure is because of the primary amino acid sequence.
