vitamin b 12 Vitamin B 12: A cobalt-containing coordination compound produced by intestinal micro-organisms and found also in soil and water. Higher plants do not concentrate vitamin B 12 from the soil and so are a poor source of the substance as compared with animal tissues. INTRINSIC FACTOR is important for the assimilation of vitamin B 12. | 3.74 | 2 | 1 | | |
digitonin Digitonin: A glycoside obtained from Digitalis purpurea; the aglycone is digitogenin which is bound to five sugars. Digitonin solubilizes lipids, especially in membranes and is used as a tool in cellular biochemistry, and reagent for precipitating cholesterol. It has no cardiac effects.. digitonin : A spirostanyl glycoside that is digitogenin in which the 3-hydroxy group is substituted by a beta-D-glucopyranosyl-(1->3)-beta-D-galactopyranosyl-(1->2)-[beta-D-xylopyranosyl-(1->3)]-beta-D-glucopyranosyl-(1->4)-beta-D-galactopyranosyl group. It is a steroidal saponin isolated from the foxglove plant, Digitalis purpurea. It is used extensively as a mild non-ionic detergent for extracting proteins from membranes for structure and function studies. | 1.95 | 1 | 0 | | |

folic acid folcysteine: used to promote fertility in chickens. vitamin B9 : Any B-vitamin that exhibits biological activity against vitamin B9 deficiency. Vitamin B9 refers to the many forms of folic acid and its derivatives, including tetrahydrofolic acid (the active form), methyltetrahydrofolate (the primary form found in blood), methenyltetrahydrofolate, folinic acid amongst others. They are present in abundance in green leafy vegetables, citrus fruits, and animal products. Lack of vitamin B9 leads to anemia, a condition in which the body cannot produce sufficient number of red blood cells. Symptoms of vitamin B9 deficiency include fatigue, muscle weakness, and pale skin. | 3.75 | 2 | 1 | folic acids; N-acyl-amino acid | human metabolite; mouse metabolite; nutrient |
