L:
(1) A
carbohydrate
that has the same
stereocenter
absolute configuration
at the second-to-last carbon in its chain (in
acyclic
form) as (
S
)-
glyceraldehyde
(also called
L
-
glyceraldehyde
).
Note that when 'L' is used to denote

glyceraldehyde)
L
-
Glucose
is the
enantiomer
of

-
glucose
.
(2) An
α-amino acid
having the
absolute configuration
shown below. Called
L
because this
amino acid
enantiomer
can (in principle) be
synthesized
from
