NEET Chemistry Proteins MCQ Question
Which of the following statements about proteins is correct?
Proteins have a primary structure that consists of a specific sequence of amino acids.
Globular proteins are always insoluble in water and have a fibrous structure.
The tertiary structure of proteins is less complex than the secondary structure.
All naturally occurring alpha-amino acids are optically inactive except glycine.
Correct Answer
Detailed Explanation
The primary structure of proteins is indeed defined by a specific sequence of amino acids, as mentioned in the NCERT context. Globular proteins are typically soluble in water and have a spherical shape, while the tertiary structure is more complex than the secondary structure. Additionally, most naturally occurring alpha-amino acids are optically active due to their asymmetric a-carbon.
