Detailed explanation-1: -Six amino acids have side chains that are polar but not charged. These are serine (Ser), threonine (Thr), cysteine (Cys), asparagine (Asn), glutamine (Gln), and tyrosine (Tyr).
Detailed explanation-2: -There are five amino acids that are polar but uncharged. These include serine, threonine, asparagine, glutamine and cysteine.
Detailed explanation-3: -Glycine (Gly), one of the common amino acids, does not have a side chain and is often found at the surface of proteins within loop or coil regions (regions without defined secondary structure), providing high flexibility to the polypeptide chain.
Detailed explanation-4: -Polar amino acids are glycine (Gly), serine (Ser), threonine (Thr), cysteine (Cys), tyrosine (Tyr), asparagine (Asn), and glutamine (Gln).
