Excessive quantities in the amniotic fluid and maternal blood may indicate spina bifida in the fetus; low levels may point to Down's syndrome amyloida complex protein resembling starch, deposited in tissues in some degenerative diseases apoproteinany conjugated protein from which the prosthetic group has been removed, such as apohaemoglobin (the protein of haemoglobin without its haem group) avidina protein, found in egg-white, that combines with biotin to form a stable compound that cannot be absorbed, leading to a biotin deficiency in the consumer calmodulina protein found in most living cells; it regulates many enzymic processes that are dependent on calcium caseinogenthe principal protein of milk, converted to casein by rennin conchiolina fibrous insoluble protein that forms the basic structure of the shells of molluscs. Formula: C30H48O11N9 dystrophina protein, the absence of which is believed to cause muscular dystrophy factor VIIIa protein that participates in the clotting of blood. It is extracted from donated serum and used in the treatment of the commonest type of haemophilia, in which it is absent ferritina protein that contains iron and plays a part in the storage of iron in the body. It occurs in the liver and spleen fibrina white insoluble elastic protein formed from fibrinogen when blood clots: forms a network that traps red cells and platelets fibrinogena soluble protein, a globulin, in blood plasma, converted to fibrin by the action of the enzyme thrombin when blood clots fibroina tough elastic protein that is the principal component of spiders' webs and raw silk flagellinthe structural protein of bacterial flagella gliadina protein of cereals, esp wheat, with a high proline content: forms a sticky mass with water that binds flour into dough globinthe protein component of the pigments myoglobin and haemoglobin glutena protein consisting of a mixture of glutelin and gliadin, present in cereal grains, esp wheat. A gluten-free diet is necessary in cases of coeliac disease hordeina simple protein, rich in proline, that occurs in barley keratina fibrous protein that occurs in the outer layer of the skin and in hair, nails, feathers, hooves, etc lactalbumina protein occurring in milk that contains all the amino acids essential to man lactoproteinany protein, such as lactalbumin or caseinogen, that is present in milk lectina type of protein possessing high affinity for a specific sugar; lectins are often highly toxic legumina protein obtained mainly from the seeds of leguminous plants leptina protein, produced by fat cells in the body, that acts on the brain to regulate the amount of additional fat laid down in the body lymphokinea protein, released by lymphocytes, that affects other cells involved in the immune response myosinthe chief protein of muscle that interacts with actin to form actomyosin during muscle contraction; it is also present in many other cell types opsinthe protein that together with retinene makes up the purple visual pigment rhodopsin osseina protein that forms the organic matrix of bone, constituting about 40 per cent of its matter priona protein in the brain, an abnormal form of which is thought to be the transmissible agent responsible for certain spongiform encephalopathies, such as BSE, scrapie, Creutzfeldt-Jakob disease, and kuru properdina protein present in blood serum that, acting with complement, is involved in the destruction of alien cells, such as bacteria ricina highly toxic protein, a lectin, derived from castor-oil seeds: used in experimental cancer therapy sclerotina protein in the cuticle of insects that becomes hard and dark sericina gelatinous protein found on the fibres of raw silk spongina fibrous horny protein that forms the skeletal framework of the bath sponge and related sponges thrombogena protein present in blood that is essential for the formation of thrombin vitellina phosphoprotein that is the major protein in egg yolk zeina protein of the prolamine group occurring in maize and used in the manufacture of plastics, paper coatings, adhesives, etc ▷ See protein
