Related to asparagine: aspartic acid

asparagine

 [ah-spar´ah-jēn]
the β-amide of aspartic acid, a nonessential amino acid that is also used as a culture medium for certain bacteria.

(as-par'ă-jin),
The β-amide of aspartic acid, the l-isomer is a nutritionally nonessential amino acid occurring in proteins; a diuretic.

asparagine

/as·par·a·gine/ (as-par´ah-jēn) (as-par´ah-jin) the β-amide of aspartic acid, a nonessential amino acid occurring in proteins; used in bacterial culture media. Symbols Asn and N.

asparagine

(ə-spăr′ə-jēn′)
n.
A nonessential amino acid, C4H8N2O3, that is present in large amounts in some plants, such as asparagus.

asparagine (Asn)

[aspar′əjin]
a nonessential amino acid found in many food and body proteins. It is easily hydrolyzed to aspartic acid and has diuretic properties. See also amino acid, protein.

Chemical structure of asparagine

asparagine

Biochemistry A nonessential amino acid which is the β-amide of aspartic acid–AA; asparaginine assists in the neural metabolism, and when the extra amino group is removed, the resulting AA acts as an excitatory transmitter and allows it to be used interchangeably with AAs in protein building
