histidine

 [his´tē-dēn]
a naturally occurring amino acid, one of the essential amino acids, necessary for optimal growth of infants; its decarboxylation results in formation of histamine.

his·ti·dine (H, His),

(his'ti-dēn),
α-Amino-1H-4; propionic acid; the l-isomer is a basic amino acid found in most proteins. It is a nutritionally essential amino acid in mammals.

histidine

/his·ti·dine/ (his´tĭ-din) (-dēn) an essential amino acid obtainable from many proteins by the action of sulfuric acid and water; it is necessary for optimal growth in infants. Its decarboxylation results in formation of histamine. Symbols His and H.

n.
An essential amino acid, C6H9N3O2, important for tissue growth and repair.

histidine (His or H)

[his′tidēn]
Etymology: Gk, histos, tissue
a basic amino acid found in many proteins and a precursor of histamine. It is an essential amino acid in infants. See also amino acid, protein.
