It has a characteristic reddish-purple color, though this can change with pH; solutions of the compound are red at pH < 3, violet at pH 7-8, and blue at pH > 11. In certain fruits, the highest concentrations of cyanidin are found in the seeds and skin. [citation needed] Cyanidin has been found to be a potent sirtuin 6 (SIRT6) activator. [2] [3]
Hesperidin is a flavanone glycoside found in citrus fruits. Its aglycone is hesperetin.Its name is derived from the word "hesperidium", for fruit produced by citrus trees. ...
Carbohydrate-containing foods are classified as high (above 70), moderate (56–69), or low (0–55) GI. [19] Foods with high fiber content generally have a low GI. However, other factors also contribute to a food's glycemic response, such as the type of carbohydrate or sugar present, the physical characteristics of the food matrix, and the ...
The fruit is often designated as "Vietnamese dragon fruit" as Vietnam is the lead exporter. [5] The fruit may also be known as a strawberry pear. [2] [6] The names pitahaya and pitaya derive from Mexico, and pitaya roja in Central America and northern South America, possibly relating to pitahaya for names of tall cacti species with flowering ...
The fruit is a round to oval single-seeded drupe, 3–6 cm (1 + 1 ⁄ 4 – 2 + 1 ⁄ 4 in) long, rarely to 8 cm (3 + 1 ⁄ 4 in) long and 3–4 cm (1 + 1 ⁄ 4 – 1 + 1 ⁄ 2 in) broad, borne in a loose pendant cluster of ten to twenty fruits together. The leathery skin is reddish (rarely orange or yellow) and covered with fleshy pliable ...
The leaves have four elliptic leaflets which are 5–12.5 cm (2.0–4.9 in) long and 2.5–5 cm (0.98–1.97 in) wide. They are typically dioecious plants, though autogamous trees occur from time to time. Flowers have four petals and eight stamens and produce void, green drupes which are 2.5–4 cm (0.98–1.57 in) long and 2 cm (0.79 in) wide ...
The fruit is sweet, juicy, and succulent in superior agricultural varieties. The seed and the peel are not consumed. Apart from being eaten raw like other fruits, longan fruit is also often used in Asian soups, snacks, desserts, and sweet-and-sour foods, either fresh or dried, and sometimes preserved and canned in syrup. The taste is different ...
Actinidain is active over a wide range of pH, including very acidic conditions, [20] with a pH optimum from 5-7. [21] At least ten different isoforms that all have the same molecular weight and cysteine protease activity as actinidain have been identified but they vary in isoelectric point from acidic (pI 3.9) to basic (pI 9.3).
