多重下拉选择题

Assign True or False to the following statements: False Amino-acids used in protein synthesis are typically D-amino-acids and mimic D-glyceraldehyde. False All amino acids used in protein synthesis have S stereocenters. True Amino-acids have a variety of sidechains with diverse properties including: alkyl,  polar, acidic, basic, and aromatic. False Proteins are made of an even mix of alpha, beta, and gamma amino-acids as coded for by DNA. False The terms protein and polypeptide are completely interchangeable. True Proteins can be used as structural materials, hormones, catalysts, protective molecules, and transport agents in cells.

The prompt asks you to assign True or False to six statements, so we’ll evaluate each statement individually and explain the reasoning behind its truth value. Statement 1: 'False Amino-acids used in protein synthesis are typically D-amino-acids and mimic D-glyceraldehyde.' This is false. In biology, proteins are built from L- amino acids (the S/U configuration for most, with the notable exception of cysteine’s R configuration as discussed later). D-amino acids are rare in standard protein synthesis and are typically found in bacterial cell walls or as antibiotics, not as the standard building blocks of human proteins.
