Question

Lipids may be amphiphilic. Ramachandran plots show that AMONG peptides made of the same amino acid (for example polylysine), a peptide made of glycine, which has the smallest side chain, has the largest combinations of allowable phi and psi angles. A peptide made of tryptophan, which has the bulkiest side chain, has the fewest combinations of allowable phi and psi angles. The Bohr effect describes the observation that a decrease of pH increases the binding affinity of O_2, because H^+ ions bind to His residues in hemoglobin and stabilize the oxygen binding form of hemoglobin.

Explanation / Answer

1. Lipids may be amphiphilic.
The answer is TRUE.

On the basis of their polarity lipids are classified in to hydrophobic and amphiphilic lipids. The example for amphiphilic lipids are Membrane lipids. They have one polar end and another non polar end. Polar end is water soluble or hydrophilic end where as the non polar end is fat soluble or hydrophobic end.
