Question

Anthocyanin occurs in
A. Chloroplasts
B. Vacuole
C. Leucoplasts
D. Chromoplasts

Answer 1

Hint: They are storage bubbles found in the cells. They occur in animal and plant cells but are much larger in plant cells. They might store food or any kind of nutrients a cell might need to survive. They can even store waste products so the rest of the cell is protected from contamination.

Complete answer:
Anthocyanins are water-soluble pigments which depending on their pH may appear red, purple, blue or black. Food plants rich in anthocyanins are the blueberry, raspberry, black rice, and black soybean, among many others that are red, blue, purple, or black.

Anthocyanins are found in the vacuole of the cell, mostly in flowers and fruits, but also in leaves, stems, and roots. In these parts of the plant, they are found predominantly in outer cell layers such as the epidermis and peripheral mesophyll cells.

Anthocyanins belong to a parent class of molecules called flavonoids which are synthesized via the phenylpropanoid pathway. They occur in all tissues of higher plants, for example leaves, stems, roots, flowers, and fruits. Anthocyanins are derived from anthocyanidins by adding sugars. They are odorless and moderately astringent.

Anthocyanins possess antidiabetic, anticancer, anti-inflammatory, antimicrobial, and anti-obesity effects, as well as prevention of cardiovascular diseases (CVDs).

Hence, the correct answer is option (B)

Note: Although approved to color foods and beverages in the European Union, anthocyanins are not approved for use as a food additive because they have not been verified as safe when used as food or supplement ingredients.
