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. ...
During fruit ripening, gluconeogenesis also increases. [9] Acids are broken down in ripening fruits [12] and this contributes to the sweeter rather than sharp tastes associated with unripe fruits. In some fruits such as guava, there is a steady decrease in vitamin C as the fruit ripens. [13]
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).
Delphinidin (also delphinidine [1] [2]) is an anthocyanidin, a primary plant pigment, and also an antioxidant. [3] Delphinidin gives blue hues to flowers in the genera Viola and Delphinium . It also gives the blue-red color of the grape variety Cabernet Sauvignon , and can be found in cranberries and Concord grapes as well as pomegranates , [ 4 ...

The fruit of C. ovatum is a drupe, 4 to 7 cm (1.6 to 2.8 in) long, 2.3 to 3.8 cm (0.91 to 1.50 in) in diameter, and weighs 15.7 to 45.7 g (0.55 to 1.61 oz). The skin ( exocarp ) is smooth, thin, shiny, and turns purplish black when the fruit ripens; the pulp ( mesocarp ) is fibrous, fleshy, and greenish yellow in color, and the hard shell ...
