Answer:
Serine (Ser), threonine (Thr), cysteine (Cys), asparagine (Asn), glutamine (Gln), and tyrosine (Tyr) are the amino acids
Explanation:
Serine (Ser), threonine (Thr), cysteine (Cys), asparagine (Asn), glutamine (Gln), and tyrosine (Tyr) are the amino acids that are polar in nature while on the other hand, alanine, cysteine, glycine, isoleucine, leucine, methionine, phenylalanine, proline, tryptophan, tyrosine and valine are the amino acids that are non-polar. Arginine, Cysteine and Histidine are the amino acids having positively charged whereas, aspartic acid and glutamic acid are the amino acid having negatively charged.
