▲'''Alanin''' (Ala), ngaran kimiana '''asam 2-aminopropanoat''' téh nyaéta [[asam amino]] non-ésénsial. Di alam, alanin aya dina dua énansiomér L-alanin jeung D-alanin. <!--L-alanin téh paling is one of the 20 amino acids most widely used in [[protein biosynthesis|protein synthesis]], second to [[leucine]], accounting for 7.8% of the [[primary structure]] in a sample of 1,150 [[proteins]] {{ref_N|1|a}}. D-alanine occurs in bacterial cell walls and in some peptide antibiotics.

Alanine is most commonly made by transfer of an amine group to [[pyruvate]]. Because transamination reactions are readily reversible, alanine can be easily formed from pyruvate and thus has close links to metabolic pathways such as [[glycolysis]], [[gluconeogenesis]], and the [[citric acid cycle]].
==FunctionGuna==

The methyl group of alanine is very non-reactive, and is thus rarely directly involved in protein function. However, alanine can play a role in substrate recognition or specificity, particularly in interactions with other non-reactive atoms such as carbon.
It goes through alanine cycle to generate glucose from protein.-->
