Question

This molecule acts as a molecular chaperone to assist in the folding of proteins
A. Vitamins
B. Carbohydrates
C. Amides
D. Lipids

Answer 1

Hint:
Before we proceed with the problem, we must know the definition of chaperones.
To function, the majority of proteins must fold into specific three-dimensional structures. However, newly synthesized proteins are highly susceptible to aberrant folding and aggregation in the cellular environment, potentially resulting in toxic species. Cells invest in a complex network of molecular chaperones that employ sophisticated mechanisms to prevent aggregation and promote efficient folding. Protein homeostasis (proteostasis) necessitates constant chaperone surveillance because protein molecules are highly dynamic.

Complete step by step answer:
There is still much to learn about chaperones.
Molecular chaperones can sometimes help proteins achieve a functional, low-energy conformation. Other proteins that can bind to unfolded polypeptides, molten globules, and other intermediates and influence how they fold are known as molecular chaperones. They frequently recognize unfolded or misfolded polypeptides by binding to exposed hydrophobic patches that are usually buried inside properly folded proteins. They can recognize other properties as well, but exposed hydrophobic side chains are the most important to the process.
Lipids are molecules that help proteins fold by acting as molecular chaperones.
Lipids are nonpolar molecules that are rich in organic compounds and energy. Lipids contain the atoms hydrogen (H), carbon (C), and oxygen (O), all of which are necessary for the proper functioning of living cells.
These molecules are made in the human liver and can be found in foods like butter, milk, and cheese.

Option ‘D’ is correct

Note:
In refolding protocols, the presence of protein molecular chaperones can significantly increase the yield of the native structure. Lipids function similarly to protein molecular chaperones, adding them to the growing list of non-protein chaperones that includes RNA and oligosaccharides. Thus, lipids act as molecular chaperones and aid in the protein folding process.
