BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Reason: Most naturally occurring amino acids have D−configuration.

Detailed explanation-2: -Reason: Most naturally occurring amino acids have D−configuration.

Detailed explanation-3: -Detailed Solution. Almost all naturally occurring form of amino acids in proteins is L-amino acids.

Detailed explanation-4: -All amino acids found in nature have an L-configuration. All amino acids are chiral except glycine. R is for Rectus, which means left, and S is for Sinister, which also means left. The R configuration denotes a clockwise rotation, while the S configuration denotes an anticlockwise rotation.

Detailed explanation-5: -These are labeled L (left-handed) and D (right-handed) to distinguish the mirror images. For some reason, the amino acids that make up the proteins in our bodies are all L-amino acids. Originally, people thought that D-amino acids did not exist in the natural world.
