    The amino acids most commonly phosphorylated are serine, threonine, tyrosine in eukaryotes, and also histidine in prokaryotes and plants (though it is now known to be common in humans). These phosphorylations play important and well-characterized roles in signaling pathways and metabolism.

    It is Phosphorylation of Serine only. Because Ser, Thr, Try has only ε-OH group. Whereas Ala doesn't have ε-OH group so it can't show Phosphorylation.

    No hydrogen is necessary for thats why it is named H2 bond. H is shared by C and O. H2O is best example where H attached with O.
