1.	Salt bridges are which kind of bonds?(a) Disulfide bond(b) H bond(c) Hydrophobic interaction(d) Electrostatic bondThe question was posed to me in a national level competition.My doubt stems from Biopharmaceuticals topic in chapter Biopharmaceuticals of Drug Biotechnology
Answer» CORRECT ANSWER is (d) Electrostatic bond Best explanation: Salt bridges are electrostatic bonds between oppositely charged GROUPS. The IONS on the R group of amino acids form salt bridges through electrostatic bonds. The STRENGTH of the bond is usually 4-7 kcal/mol.
