Question

State which of these amino acids have R groups that would: a. be found in hydrophobic regions b. be found in hydrophilic regions c. form hydrogen bonds d. form salt bridges Drag the appropriate items to their respective bins. Items may be used more than once. Reset Help aspartate aspartato glycine alycine arginine arginine R groups in hydrophobic regions R groups in hydrophilic regions R groups forming hydrogen bonds Rgroups forming salt bridges

Answer 1

Glycine is the smallest amino acid with the R group= H

Because of the small size of H atom it can be present in both hydrophobic or hydrophilic region. Also it can form upto 5 H-bonds but it can't form salt bridges.

Aspartate R group is polar so it will be found in hydrophillic regions only.

They can form H-bonds and form salt bridges too.

Arginine R group is also polar so it will be found in hydrophillic regions. Can form H-bonds and salt bridges.

1. R groups in Hydrophobic regions- Glycine

2. R groups in hydrophillic regions- Glycine, aspartate and arginine.

3. R groups forming H-bonding- Glycine, aspartate, arginine.

4. R groups forming salt bridges- Aspartate and arginine.
