Chondrus-crispus is a species of red algae which grows abundantly along the rocky parts of the Atlantic coast of Ireland. In its fresh condition this protist is soft and cartilaginous, varying in color from a greenish-yellow, through red, to a dark purple or purplish-brown.
The principal constituent is a mucilaginous body, made of the polysaccharide carrageenan, which constitutes 55% of its weight. The organism also consists of nearly 10% protein and about 15% mineral matter, and is rich in iodine and sulfur. When softened in water it has a sea-like odour and because of the abundant cell wall polysaccharides it will form a jelly when boiled, containing from 20 to 100 times its weight of water.
Commercial use: Irish Moss has been used in Ireland since the beginning of the 19th century as a folk remedy for respiratory ailments. During the famine in Ireland emigrates exported the Irish moss to New England in the USA where it was used for sizing ropes and cooking.
Two types of carrageen. Chondrus crispus and Mastocarpus stellatus,
Tests done by J.Collen and I.R.Davison
(1) M. stellatus is better able to tolerate reactive oxygen than C. crispus, which could partly explain the higher stress tolerance of M. stellatus.
(2) Mastocarpus stellatus scavenges reactive oxygen more efficiently than C. crispus, with higher contents of anti-oxidants and/or higher activities of reactive oxygen scavenging enzymes.
(3) Chondrus crispus, but not M. stellatus, exhibits changes in reactive oxygen metabolism with tidal height, caused by its ability to acclimatize.
