papain

 [pah-pa´in, pah-pi´in]
a proteolytic enzyme from the latex of papaw, Carica papaya, the active ingredient of meat tenderizers. In medicine, it is used as a protein digestant and for enzymatic débridement and promotion of normal healing of surface lesions.

pa·pa·in

, papainase (pa-pā'in, -ās),
A cysteine endopeptidase, or a crude extract containing it, obtained from papaya latex. It has esterase, thiolase, transamidase, and transesterase activities; is used as a protein digestant, meat tenderizer, and to prevent adhesions. Formerly used to liquify contents of herniated intervertebral discs so that their contents could be removed by aspiration.
Synonym(s): papayotin

papain

/pa·pa·in/ (pah-pa´in) (pah-pi´in) a proteolytic enzyme from the latex of papaw, Carica papaya, which catalyzes the hydrolysis of proteins and polypeptides to amino acids; used as a protein digestant and as a topical application for enzymatic débridement.

papain

(pə-pā′ĭn, -pī′ĭn)
n.
An enzyme obtained from the unripe fruit of the papaya that catalyzes the lysis of proteins, used especially as a meat tenderizer and digestive aid and formerly in medicine as a topical treatment for wounds.

papain

[pəpā′ēn]
an proteolytic enzyme from the fruit of Carica papaya, a tropical melon tree. It is prescribed for enzymatic debridement of wounds and promotion of healing.

papain

A mixture of enzymes found in pawpaws. Papain includes the protein-splitting enzyme chymopapain and this makes it useful for breaking down organic debris and so cleaning up wounds and ulcers. Chymopapain is used to break down material extruded from the pulpy nuclei of intervertebral discs (chemonucleolysis).

papain (p·pāˑ·in),

n a proteolytic enzyme found in the juice of the unripe papaya fruit; used to facilitate digestion. Allergic reaction may occur after topical application or oral ingestion.

A cysteine endopeptidase, or a crude extract containing it, obtained from papaya latex. It has esterase, thiolase, transamidase, and transesterase activities; is used as a protein digestant, meat tenderizer, and to prevent adhesions.

papain (pəpā´in),

n an enzyme from papaya, a tropical fruit; used for enzymatic debridement of wounds and for promotion of healing.

papain

a proteolytic enzyme from the latex of pawpaw, Carica papaya, the active ingredient of meat tenderizers. In surgery it is used as a protein digestant and for enzymatic débridement and promotion of normal healing of surface lesions. Papain is also used in immunology to cleave immunoglobulin molecules into Fab and Fc fragments.
