Give the examples of Acidic, basic and neutral amino acids respectively.

Answer» There are three\xa0amino acids\xa0that have\xa0basic\xa0side chains at\xa0neutral pH. ... For these\xa0amino acids, the protonated forms predominate at physiological\xa0pH\xa0(about 7). Two\xa0amino acids\xa0have\xa0acidic\xa0side chains at\xa0neutral pH. These are aspartic\xa0acid\xa0or aspartate (Asp) and glutamic\xa0acid\xa0or glutamate (Glu).\xa0Histidine is the\xa0most basic amino acid\xa0in the given compound. This can be attributed to the fact that the histidine contains the\xa0most\xa0number of a\xa0basic\xa0nitrogen atom.\xa0Normally, an\xa0amino acid\xa0produces a nearly\xa0neutral\xa0solution since the\xa0acid\xa0group and the basic amine group on the root\xa0amino acid\xa0neutralize each other in the zwitterion. If the\xa0amino acid\xa0structure contains two\xa0acid\xa0groups and one amine group, there is a net\xa0acid\xa0producing effect.
