WebView the full answer. Transcribed image text: Which of the following is true regarding the chirality of amino acids found in proteins? Only L amino acids are found in proteins. O only D amino acids are found in proteins. @ Proteins contain both D and L amino acids. O D amino acids alternate with L amino acids in certain regions of proteins. WebAmino acids are built by protein biosynthesis, which involves the activation of amino acids followed by their addition to a growing polypeptide chain. During activation, an amino acid is linked to a transfer RNA (tRNA) molecule specific to that amino acid, forming an aminoacyl-tRNA. Explanation: Amino acids are the building blocks of proteins ...

Webchiral molecules such as amino acids, proteins and sugars in one particular enantiomeric form. Why homochirality is important Homochirality is an essential property of all known forms of life.
