Question

What are examples of primary, secondary, tertiary, and quarternary of protein structure?

Answer 1

Primary;- insulin 
Secondary;- actin, myosin 
Tertiary;- all enzymes such as lipase, sucrase 
Quaternary;- hemoglobin

Answer 2

Explanation:

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)
