We all know that polar amino acids like Serine, Threonine, Glutamine etc. form H-bonds using their side chains. Is it possible for aliphatic Amino acids to make H-bonds using their side-chains?

$\begingroup$ Carbon is not electronegative enough so there is little difference between carbon and hydrogen electronegativity. Hydrogen bonding only arises when hydrogen is attached to a highly electronegative element (see ncbi.nlm.nih.gov/pmc/articles/PMC3516709) $\endgroup$– WaylanderMar 19 at 21:22
