Question

describe the secondary and tertiary structure of protein​

Answer 1

Answer:

secondary structure of a protein :

the sequence in which amino acids are arranged in a polypeptide chain of a protein is called its primary sturcture ...

secondary structure :

some portion of the protein thread are folded either in the form of a helix ( similar to a revolving stair case ) or beta - pleated sheet

the two types :

alpha - helix ...

beta - pleated sheet ...

Answer 2

Answer:

Tertiary structure:

• The long protein chain of the

polypeptide chain usually folds

upon itself like a hollow woollen

ball. This is termed as tertiary

structure. This structure gives a

3-dimensional view of protein.

• Tertiary structure is absolutely

necessary for the many

biological activities of proteins

for example, this structure

brings distant amino acid side

chains closer forming the active

site (the site to which a

substrate gets attached) of

proteins i.e., enzymes. e.g.,

Myoglobin (protein found in

muscle cell)
