Arginine is an essential amino acid for birds, as they do not have a urea cycle. [19] For some carnivores, for example cats, dogs [ 20 ] and ferrets, arginine is essential, [ 3 ] because after a meal, their highly efficient protein catabolism produces large quantities of ammonia which need to be processed through the urea cycle, and if not ...
The anhydroglucose unit (AGU) refers to a single sugar molecule in a polymer. Each AGU is reduced to its functional groups, 3 hydroxyl groups per AGU. Each AGU is reduced to its functional groups, 3 hydroxyl groups per AGU.

Aspartylglucosaminuria is an autosomal recessive genetic condition that is inherited from both parents. The AGU patient is born with two copies of the mutated AGA gene. One copy comes from the mother's egg and the other copy comes from the father's sperm. [2]
The basic proteoglycan unit consists of a "core protein" with one or more covalently attached glycosaminoglycan (GAG) chain(s). [2] The point of attachment is a serine (Ser) residue to which the glycosaminoglycan is joined through a tetrasaccharide bridge (e.g. chondroitin sulfate - GlcA - Gal -Gal- Xyl -PROTEIN).
Argininosuccinic acid is a non-proteinogenic amino acid that is an important intermediate in the urea cycle. [ 1 ] It is also known as argininosuccinate . [ 2 ]
The amino end of an amino acid (on a charged tRNA) during the elongation stage of translation, attaches to the carboxyl end of the growing chain. Since the start codon of the genetic code codes for the amino acid methionine , most protein sequences start with a methionine (or, in bacteria, mitochondria and chloroplasts , the modified version N ...
Homoarginine is an nonproteinogenic alpha-amino acid. It is structurally equivalent to a one-methylene group-higher homolog of arginine and to the guanidino derivative of lysine. L-Homoarginine is the naturally-occurring enantiomer.
