Are anthocyanins enzymes?
Are anthocyanins enzymes?
They are responsible for the red, purple, and blue colors in roots, leaves, flowers, fruit, and other plant tissues. Because both the synthesis and degradation of anthocyanins are enzymatically controlled in planta, changes in these two processes should benefit plants.
What is the difference between anthocyanin and Anthocyanidin?
Anthocyanin and anthocyanidin are two types of red-blue plant flavonoids, mostly found in flowers and fruits of higher plants. The main difference between anthocyanin and anthocyanidin is that anthocyanin is a water-soluble vacuolar pigment whereas anthocyanidin is the sugar-free counterpart of anthocyanin.
How do plants produce anthocyanin?
Anthocyanins are water-soluble pigments produced via the flavonoid pathway in the cytoplasm of the colored plant cell. These are responsible for the pink-red colors of most flower petals, of most red fruits (like apples) and almost all red leaves during the autumn.
What type of compound is anthocyanin?
Anthocyanins are colored water-soluble pigments belonging to the phenolic group. The pigments are in glycosylated forms. Anthocyanins responsible for the colors, red, purple, and blue, are in fruits and vegetables.
How does anthocyanin help plants?
Anthocyanins are a group of polyphenolic pigments that are ubiquitously found in the plant kingdom. In plants, anthocyanins play a role not only in reproduction, by attracting pollinators and seed dispersers, but also in protection against various abiotic and biotic stresses.
Is anthocyanin an acid?
In acidic condition, anthocyanin appears as red pigment while blue pigment anthocyanin exists in alkaline conditions. Anthocyanin is considered as one of the flavonoids although it has a positive charge at the oxygen atom of the C-ring of basic flavonoid structure.
Does anthocyanin prevent photosynthesis?
It is conceivable that anthocyanins protect the photosynthetic apparatus against photodamage by reducing visible light under conditions when UV-radiation inhibits photosynthesis. However, high visible light levels alleviate many of the detrimental effects of UV-B radiation (Teramura, 1980; Caldwell et al., 1994).
