Description of DL-Ala-OH
Alanine (abbreviated as Ala or A; encoded by the codons GCU, GCC, GCA, and GCG) is an α-amino acid that is used in the biosynthesis of proteins. It contains an α-amino group (which is in the protonated −NH3+ form under biological conditions), an α-carboxylic acid group (which is in the deprotonated −COO− form under biological conditions), and a side chain methyl group, classifying it as a nonpolar (at physiological pH), aliphatic amino acid. It is non-essential in humans, meaning the body can synthesize it.
The L-isomer (left-handed) of alanine is one of the 20 amino acids encoded by the human genetic code. L-Alanine is second only to leucine in rate of occurrence, accounting for 7.8% of the primary structure in a sample of 1,150 proteins. The right-handed form, D-Alanine occurs in bacterial cell walls and in some peptide antibiotics.

What is DL-Ala-OH?
- With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is DL-Alanine which has developed particularly rapidly in recent years. Do you know about DL-Alanine?a
- The official answer: DL-Alanine, a chemical with the molecular formula C3H7NO2, is used as a raw material for the manufacture of vitamin B6 and medical microbiological and biochemical amino acid metabolism.
What’s the application of DL-Ala-OH?
It has a special sweetness, sweeter than stachyose, and is 1.6 times sweeter than glycine, which is one of the sweetest amino acids. Alanine is a non-essential amino acid to human body, but it can produce reversible conversion with pyruvic acid, which is related to sugar metabolism and is very important in physiological process. Mainly used as a food additive, it can be used alone or made into a compound condiment with sodium glutamate, etc. Its largest sales volume is the sweet compound condiment. It is mainly used alone as an additive for pickling of savory and sweet pickles. In addition, it is also used as an additive for vinegar, soy sauce and fruit juice, with a general dosage of 0.1%-0.5%. DL-alanine is also used as a pharmaceutical intermediate.
