Amino Acid Chart Chemtalk

Amino Acid Chart Chemtalk In each amino acid, an amino group and a carboxylic acid group attach to a carbon. however, amino acids are different from each other based on the composition of their r groups. amino acid structure. 20 amino acids make up all proteins. to repeat, the only difference in their structures is their r groups. the simplest or smallest amino acid is. Amino acids are the building blocks of a larger (well known) macromolecule, proteins. they consist of a carbon bonded to a hydrogen atom, carboxyl group, amino group, and a variable group. the cooh on the right hand side of the photo above is the carboxyl group. the carboxyl group is usually very important in enzymatic protein transport.

Amino Acid Chart Chemtalk Amino acids connect to one another by special covalent bonds, called peptide bonds. these bonds form when a carboxyl group of one amino acid (o=c oh) reacts with an amine group ( nh2) of another. this reaction is called a dehydration reaction, because water is released in the process. the entire process is shown below. Amino acid abbreviations and molecular weights. the average molecular weight of an amino acid is 110da. dalton (da) is an alternate name for the atomic mass unit, and kilodalton (kda) is 1,000 daltons. thus a protein with a mass of 64kda has a molecular weight of 64,000 grams per mole. Glycine (gly g) is the amino acid with the shortest side chain, having an r group consistent only of a single hydrogen. as a result, glycine is the only amino acid that is not chiral. its small side chain allows it to readily fit into both hydrophobic and hydrophilic environments. figure 2.3 non polar amino acids. The structures, abbreviations (both three and one letter), and pk a values of the 20 amino acids commonly found in proteins are shown in table 26.1.all are α amino acids, meaning that the amino group in each is a substituent on the α carbon—the one next to the carbonyl group.

Eight of the 20 amino acids are non polar: alanine, glycine, isoleucine, leucine, methionine, phenylalanine, proline, and valine. the final four are polar charged: arginine, aspartic acid, glutamic acid, and lysine. a downloadable study sheet of this information is available here. table of 20 amino acids derived from proteins with the amino.
