Which amino acid is Arg?

Arginine R
Arginine, an essential amino acid, has a positively charged guanidino group. Arginine is well designed to bind the phosphate anion, and is often found in the active centers of proteins that bind phosphorylated substrates.

Which isomer R )- threonine or S )- threonine is D threonine?

Threonine has two chiral centers and therefore four possible stereoisomers. The isomers other than Thr (D-, L-allo-, and D-allo-threonine) are rare in nature and have no value, nutritional or otherwise….L-Threonine fast facts.

CAS Reg. No.	72-19-5
Melting point	228–270 ºC (dec.)*
Water solubility	97 g/L

Are all amino acids L or D?

L amino acids
The amino acids are all chiral, with the exception of glycine, whose side chain is H. As with lipids, biochemists use the L and D nomenclature. All naturally occurring proteins from all living organisms consist of L amino acids.

Which amino acids are D and L?

L- and D-amino acids are usually enantiomers. The exceptions are two amino acids with two stereogenic centers, threonine and isoleucine. Aside from those two special cases, L- and D-amino acids have identical properties (color, solubility, melting point) under many conditions.

Does threonine have a hydroxyl group?

Two amino acids, serine and threonine, contain aliphatic hydroxyl groups (that is, an oxygen atom bonded to a hydrogen atom, represented as ―OH).
