WebAlanine is a strong α-helix forming amino acid and does not significantly contribute to turn or β-sheet formation. AAPPTec provides Fmoc, Boc, and Z protected alanine as well as alanine esters with 99+% purity. High purity amino acid derivatives from AAPPTec produce higher peptide yields and purer peptides. WebAll amino acids have the same basic structure, shown in Figure 2.1. At the center of each amino acid is a carbon called the. α carbon. and attached to it are four groups – a hydrogen, a carboxylic acid group, an amine group, and an R-group, sometimes referred to as a variable group or side chain. The α carbon, carboxylic acid, and amino ...
