ácido ascórbico |
|
| trade name: generic; many brand names; drug class: vitamin C, water-soluble vitamin; action: needed for wound healing, collagen synthesis, antioxidant, carbohydrate metabolism; uses: vitamin C deficiency, scurvy, delayed wound and bone healing, chronic disease, urine acidification, before gastrectomy; (vitamin C, antiscorbutic factor), a water-soluble vitamin resembling glucose in structure; it is found in citrus fruits, tomatoes, cabbage, and other fresh fruits and vegetables. Necessary for hydroxylation of peptide-bound lysine and proline to hydroxylysine and hydroxyproline during collagen synthesis. A deficiency leads to scurvy, in which pathologic signs are confined mainly to the connective tissues with hemorrhages, loosening of teeth, gingivitis, and poor wound healing. |

ácido láctico |
|
| a monobasic acid, C3H6O3, formed as an end product in the intermediary metabolism of carbohydrates. The accumulation of lactic acid in the tissues is in part responsible for the lowering of pH levels during inflammatory states; that is, the drop in pH level is believed to hasten bone resorption in periodontitis because the minerals in the bone are stable within the matrix only at the normal tissue pH level of 7.4. |

acid, nicotinic |
ácido nicotínico |
|
| 1. one of the vitamins of the B complex group and its vitamer, niacinamide, specific for the treatment of pellagra. Niacinamide functions as a constituent of coenzyme I (DPN) and coenzyme II (TPN). Nicotinic acid is found in lean meats, liver, yeast, milk, and leafy green vegetables. 2. an acid (C5H4N [COOH]) that forms part of the B complex group of vitamins. The body requires this acid as a cofactor in intermediary carbohydrate metabolism. This acid is a constituent of certain coenzymes that function in oxidative-reductive metabolic systems. With niacinamide, nicotinic acid is a pellagra-preventive factor. Also called niacin, P.-P. factor, pyridine 3-carboxylic acid, vitamin P.-P. |
