These rules sometimes lead to absurd results when they are applied to biochemical molecules. For example, as we have seen, all of the common amino acids are L, because they all have exactly the same structure, including the position of the R group if we just write the R group as R.
Are D or L sugars more common?
As the l-isomer of glucose, it is the enantiomer of the more common d-glucose. l-Glucose does not occur naturally in living organisms, but can be synthesized in the laboratory.
Why do all biological systems use L amino acids and D sugars?
It is significant that all biological systems use L-amino acids and D-sugars because they are important for life. Their structures allow the molecules to perform functions that are essential to living systems. … This is because the same isomers function and have the same properties in all organisms.
