Native to tropical America, sweet potato (I. batatas) is a perennial morning glory vine that has been cultivated for over 5,000 years for its edible tubers in Mexico, Central and lowland South America, and the West Indies. Today, sweet potato is cultivated around the world, especially in developing countries (Plate 4). A decoction made from the leaves of this plant is used in folk remedies as a gargle to treat mouth and throat tumors, and poultices are prepared for inflammatory tumors (64). In Mexico, leaf decoctions are considered to be of cold nature , to reduce excessive body heat, contemporarily defined as such illnesses as diarrhea, dysentery, heart disease, stomach distress, fever, and gastrointestinal infection. In Chinese traditional medicine, the tubers have been used as a medicinal herb to eliminate secretion in perceived abnormal quantities of blood or other body fluids (79). [Pg.142]

The International Potato Center, known worldwide by its Spanish acronym CAP, sees the potato and other Andean root and tuber crops as underexploited resources for agricultural development and hunger relief in developing countries. Founded in 1971, CIP has worked to enhance the cultivation, yield, processing, and consumption of potatoes. Its original mandate was expanded to include sweet potatoes and, more recently, other Andean roots and tubers in danger of extinction. [Pg.551]

Similar Mn-containing enzymes were subsequently isolated from other plant sources spinach leaves (71), rice plant cultured cells (72), soybeans (73-75), and the tubers of the sweet potato Kintoki (76-81) (Table III). Sweet potatoes have recently been reported to possess two different acid phosphatases which were immunologically distinct but which have similar molecular weights and metal content (106). Interestingly, sulfhydryl reagents have been shown to inactivate the soybean enzyme (75). [Pg.203]

Presently, the vast majority of information on the Mn site in these acid phosphatases comes from the enzyme from sweet potato tubers. This 110-kDa enzyme is identical to the previously reported sweet potato enzyme likewise, a 55-kDa subunit was found (78). However, the enzyme possesses only one Mn per enzyme molecule. At 293 and 77 K, no EPR signal could be detected for the native enzyme. Inactivation of the enzyme by heat treatment or the addition of acid results in the appearance of a six-line EPR pattern due to aquated Mn(II). As in the case of Mn SODs, this was taken as evidence for Mn(III) in the native... [Pg.203]

Sweet potatoes are perennial vegetables grown as annuals in temperate regions for their tuberous roots. While they are tropical natives, you can grow them if you get at least 100 frost-free days. Cultivars have light yellow to purplish red skin, and white to deep orange flesh. [Pg.220]

Starch [9005-25-8], (C6H10O5)k, the main reserve food of plants, constitutes two-thirds of the carbohydrate caloric intake of most humans but only 47% of the carbohydrate caloric intake by Americans, who also get about 52% of their carbohydrate calories from sugar. Commercial starches are obtained from seeds, particularly com, waxy com, high amylose com, wheat, and rice, and from tubers or roots particularly potato, sweet potato, and tapioca (cassava). Their principal use is in foods the major nonfood uses are in sizing of paper and textiles, and as adhesives (qv). [Pg.340]

In 1999, sweet potato accounted for approximately 20% of the total world production of root and tuber crops (FAO, 1999). Asia is the largest sweet potato-producing region in the world, with an annual production of 125 million tonnes. China produces roughly 65% of the world s sweet potato, making it the leading supplier of sweet potatoes in the world (Hijmans et al., 2002). Latin America and North America produce about 1.9 million and... [Pg.7]

It is proposed that NAD is required for the oxidation of DAMP to a diketone intermediate. The latter compound than undergoes a phosphate elimination yielding a product that undergoes a NADH-dependent reduction to form a dideoxy diketone. This intermediate cyclizes to yield dehydroquinate (Sprinson et al., 1%2 Aldersberg and Sprinson, 1964). Recently, 5-dehydro-3-deoxy-D-arabino-heptulosonic acid 7-phosphate was shown to be an intermediate in the reaction (Maitra and Sprinson, 1978). Sliced sweet potato root and potato tuber tissue show increased DHQ syntlfase activity reminiscent of the injury-stimulated increases in those tissues of phenylalanine ammonia lyase and other enzymes of phenolic biosynthesis (Saijo and Kosuge, 1978). [Pg.514]
