Alanine is the simplest α-amino acid after glycine. The methyl side-chain of alanine is non-reactive and is therefore hardly ever directly involved in protein function. [12] Alanine is a nonessential amino acid, meaning it can be manufactured by the human body, and does not need to be obtained through the diet. Alanine is found in a wide ...
β-Alanine (beta-alanine) is a naturally occurring beta amino acid, which is an amino acid in which the amino group is attached to the β-carbon (i.e. the carbon two carbon atoms away from the carboxylate group) instead of the more usual α-carbon for alanine (α-alanine). The IUPAC name for β-alanine is 3-aminopropanoic acid.
The Cahill cycle, also known as the alanine cycle or glucose-alanine cycle, [1] is the series of reactions in which amino groups and carbons from muscle are transported to the liver. [2] It is quite similar to the Cori cycle in the cycling of nutrients between skeletal muscle and the liver. [ 1 ]
The alpha helix is also commonly called a: Pauling–Corey–Branson α-helix (from the names of three scientists who described its structure); 3.6 13-helix because there are 3.6 amino acids in one ring, with 13 atoms being involved in the ring formed by the hydrogen bond (starting with amidic hydrogen and ending with carbonyl oxygen)

The three substrates of the enzymatic reaction are an L-amino acid, water, and oxygen, whereas the three products are the corresponding α-keto acid (2-oxo acid), ammonia, and hydrogen peroxide. One example of the enzyme in action occurs with the conversion L-alanine into pyruvic acid (2-oxopropanoic acid), as shown in Figure 1.
The amino acid glutamate is used to neutralize the ammonia produced when AMP is converted into IMP. Another amino acid, aspartate, is used along with IMP to produce S-AMP in the cycle. Skeletal muscle contains amino acids for use in catabolism, known as the free amino acid pool; however, inadequate carbohydrate supply and/or strenuous exercise ...
Amino acid biosynthesis overview. The drawn molecules are in their neutral forms and do not fully correspond to their presented names. Humans can not synthesize all of these amino acids. Amino acid biosynthesis is the set of biochemical processes (metabolic pathways) by which the amino acids are produced.
