Proteins are constructed using amino acids that have side chains, which allow for unique chemical properties to be expressed. Explore four types of amino acid side chains: nonpolar, polar, basic, and acid. Related to this QuestionWhich of the following amino ...

1. Non-polar 2. Polar 3. Acidic and polar 4. Basic and polar For example, side chains having pure hydrocarbon alkyl or aromatic groups are considered non-polar, and these amino acids are comprised of Phenylalanine, Glycine, Valine, Leucine, Alanine, Isoleucine, Proline, Methionine and Tryptop...
The amino acids with polar uncharged R groups are serine (S, Ser, HO-CH2-CH(NH2)-COOH), threonine (T, Thr, CH3-CH(OH)-CH(NH2)-COOH), cysteine (C, Cys, HS-CH2-CH(NH2)-COOH), proline (P, Pro, NH-(CH2)3-CH-COOH), asparagine (N, Asn, H2N-CO-CH2-CH(NH2)-COOH) and ...

Aspartic acid (Asp or D) ((2S)-2-aminobutanedioic acid) is a polar, acidic, negatively charged amino acid with the formula HOOCCH(NH2)CH2COO−. The side chains of Asp and Glu are nearly always negatively charged at physiological pH; therefore, these amino acids are usually called asparta...
3. Basic. The amine functional group allows the amino acid side chain to accept a proton under physiological conditions (pH of about 7). Thus, this amino acid would be classed as basic and also as “positively-charged.” 4. Polar, uncharged. The amide functional group causes the amino ac...

and they are vital to many processes in the body as well. There are 20 main amino acids used by the body, and they all consist of a central carbon that is bonded to an amino group, a carboxyl group, a hydrogen, and a unique side chain that makes ...
