Question

define structure of protein??​

Answer 1

Protein primary structure is the linear sequence of amino acids in a peptide or protein. By convention, the primary structure of a protein is reported starting from the amino-terminal end to the carboxyl-terminal end. Protein biosynthesis is most commonly performed by ribosomes in cells

Answer 2

PROTEIN :

$\leadsto$ Protein are the building blocks of the body and life.

$\leadsto$ Proteins are commonly found in all the living organsims.

STRUCTURE OF PROTEIN :

• Proteins are chain of the amino acids.
• This amino acids are linked to each other and makes chain in the body.
• The chain of protein is formed by hydrogen bonding in the polypeptide chain.
• Structure of protein are classified into three levels they are : primary, secondary, tertiary and Quaternary.

1. Primary :

$\longrightarrow$ The primary structure of protein is formed by chain of amino acids.

2. Secondary :

$\longrightarrow$ It is formed by the bonding of hydrogen in polypeptide chain.

3. Tertiary :

$\longrightarrow$ It is a coiled structure.

4. Quaternary :

$\longrightarrow$ The proteins which have multiple polypeptide chains forms the large complex protein.
