Vitamin K is necessary for the liver to produce the coagulation factors II, VII, IX, and X, as well as the clotting factors protein C, protein S, and protein Z; vitamin K deficiency can result in deficiencies of these coagulation factors and excess bleeding. An injection of vitamin K is routinely given to newborn infants to prevent vitamin K deficiency bleeding, also known as hemorrhagic disease of the newborn. Vitamin K deficiency is rare in adults but may result from chronic malnutrition or an inability to absorb dietary vitamins." ;

  rdfs:label "Ricin" ;
  rdfs:comment "A phytotoxin and lectin comprised of a homodimer of ricin toxin A and B chains derived from the seeds of Ricinus communis, the castor oil plant, with protein synthesis inhibitory activity and extremely high cytotoxicity. Following ingestion, inhalation or injection of ricin, the B chain binds to complex carbohydrates containing either terminal N-acetylgalactosamine or beta-1,4-linked galactose residues on the surface of cells. Subsequently, the ricin A/B heterodimer is internalized and undergoes retrograde transport to the endoplasmic reticulum (ER). In the ER, the A chain, which has enzymatic activity that is sterically hindered by the B chain, is proteolytically released from the heterodimer by protein disulfide isomerase. In the ER, the free A chain has N-glycosidase activity that cleaves 28S rRNA. This enzymatic cleavage disrupts the ribosome, halts protein synthesis, and can lead to cell death. The extreme cytotoxicity of ricin makes it an attractive candidate for artificial fusion with binding proteins to create cell-type-specific toxins." ;

  rdfs:label "Niacin" ;
  rdfs:comment "A water-soluble vitamin belonging to the vitamin B family, which occurs in many animal and plant tissues, with antihyperlipidemic activity. Niacin is converted to its active form niacinamide, which is a component of the coenzymes nicotinamide adenine dinucleotide (NAD) and its phosphate form, NADP. These coenzymes play an important role in tissue respiration and in glycogen, lipid, amino acid, protein, and purine metabolism. Although the exact mechanism of action by which niacin lowers cholesterol is not fully understood, it may act by inhibiting the synthesis of very low density lipoproteins (VLDL), inhibiting the release of free fatty acids from adipose tissue, increasing lipoprotein lipase activity, and reducing the hepatic synthesis of VLDL-C and LDL-C." ;
