Left-handed helix in proteins secondary structure is called as _ :
Correct answer: B. Beta helix
- A. Alpha helix
- B. Beta helix
- C. Spiral
- D. Concentrate
Explanation
Left handed helix in protein secondary structure is known as alpha helix. A type of helical structure with a left-handed twist is called beta helix. It is different from the given statement, hence, this option is incorrect. Spiral is a term used to describe any coiled or helical structure. As it is a general term, this option is incorrect. The term 'concentrate' is not related to proteins, hence, this option is incorrect. Only option A relates to the given statement so it is correct.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
