Question

Cow’s milk is more nutritious and slightly yellow due to the presence of
A. Vitamin D
B. Ascorbic acid
C. Riboflavin
D. Carotene

Answer 1

Hint: It is a photosynthetic pigment found in various plants, bacteria, and algae. It also acts as antioxidants in the human body.

Complete answer:
Cow milk contains a coloring pigment Beta-carotene which is found in the grass where the cows graze on. Carotenoid is a precursor of vitamin-A which gets converted into enterocytes and hepatocytes of animals. It is a fat-soluble pigment responsible for the yellow color of milk and milk products like cream, butter, ghee, etc. β-Carotene is an antioxidant that serves various immune regulatory properties.

Additional information:
> Cow's milk contains lactose which is a disaccharide of carbohydrate and composed of glucose and galactose.
> Cow's milk contains about 30-35 gm of proteins per liter.
> Cow milk proteins are generally classified into caseins, whey proteins, and milk fat globular membrane proteins.
> India is the second-largest cow milk producing country.
> Cow milk has amino acids and vitamins which makes the protein that helps in food digestion.
> It helps strengthen and support the immune system and reduces the chances of cancer.
> Cow milk is more nutritious and healthier than any other animal’s milk.
> The major whey protein in cow milk includes Beta-lactoglobulin which is a small globular protein with a β-barrel structure. It is capable enough to bind with hydrophobic ligands.

So, the correct answer is ‘carotene’.

Note:
- Lactose intolerance is a digestive disorder in which a person is unable to digest the lactose. It is the main carbohydrate in milk and milk products.
- It occurs due to the absence of lactase enzymes in individuals that degrade the lactose into glucose and galactose.
