Vitamin A is stored in the human body primarily in the (a) Liver. The liver functions as a crucial organ for storing and metabolizing nutrients, including fat-soluble vitamins like Vitamin A. It stores excess Vitamin A obtained from the diet or synthesized from provitamin sources, such as beta-carotene found in fruits and vegetables.
Stored Vitamin A in the liver can be mobilized and released into circulation as needed, contributing to maintaining optimal levels of this essential nutrient in the body. This stored reservoir of Vitamin A ensures a steady supply of the vitamin for various physiological functions, including vision, immune function, and cellular growth and differentiation.
While the stomach (b) plays a role in digestion and absorption of nutrients, it is not a storage site for Vitamin A or other vitamins. The spleen (c) primarily functions in immune response and blood filtration, not nutrient storage.
Carrot is a rich source of (a) Vitamin A. Carrots contain high levels of beta-carotene, a provitamin that the body converts into Vitamin A. Vitamin A is essential for maintaining healthy vision, supporting immune function, promoting skin health, and ensuring proper growth and development. Beta-carotRead more
Carrot is a rich source of (a) Vitamin A. Carrots contain high levels of beta-carotene, a provitamin that the body converts into Vitamin A.
Vitamin A is essential for maintaining healthy vision, supporting immune function, promoting skin health, and ensuring proper growth and development.
Beta-carotene, a powerful antioxidant found in carrots, helps protect cells from oxidative stress and may reduce the risk of chronic diseases such as heart disease and certain cancers.
Consuming carrots and other foods rich in Vitamin A contributes to overall health and well-being. Including a variety of colorful fruits and vegetables in the diet ensures an adequate intake of essential vitamins and minerals, supporting optimal health and reducing the risk of nutrient deficiencies and associated health problems.
Vitamin is called a protective substance. Vitamins are essential micronutrients that play crucial roles in supporting overall health and protecting the body against various diseases and deficiencies. They act as antioxidants, immune boosters, and cofactors in enzymatic reactions, contributing to numRead more
Vitamin is called a protective substance. Vitamins are essential micronutrients that play crucial roles in supporting overall health and protecting the body against various diseases and deficiencies. They act as antioxidants, immune boosters, and cofactors in enzymatic reactions, contributing to numerous physiological functions.
Vitamins help maintain healthy skin, vision, and bone health; support immune function; and participate in energy metabolism. Deficiencies in vitamins can lead to various health issues and increase susceptibility to infections and chronic diseases.
While proteins, carbohydrates, and fats primarily serve as energy sources and structural components in the body, vitamins are essential for regulating metabolism, supporting growth and development, and ensuring the proper functioning of organs and systems. Thus, vitamins are rightfully referred to as protective substances due to their critical roles in maintaining overall health and well-being.
Vitamin does not provide energy. Vitamins are essential micronutrients required in small amounts for various physiological functions in the body, such as metabolism, immune function, and tissue repair. Unlike macronutrients such as carbohydrates, proteins, and fats, vitamins do not directly provideRead more
Vitamin does not provide energy. Vitamins are essential micronutrients required in small amounts for various physiological functions in the body, such as metabolism, immune function, and tissue repair. Unlike macronutrients such as carbohydrates, proteins, and fats, vitamins do not directly provide energy when metabolized.
Carbohydrates, proteins, and fats are considered energy-yielding macronutrients because they contribute calories to the diet. Carbohydrates and proteins each provide 4 calories per gram, while fats provide 9 calories per gram. These macronutrients are broken down and metabolized to produce energy in the form of adenosine triphosphate (ATP), the body’s primary energy currency, which fuels cellular processes and physical activity.
While vitamins play crucial roles in supporting energy metabolism and overall health, they do not themselves provide calories or energy when consumed. Instead, they act as cofactors or coenzymes in enzymatic reactions that facilitate energy production and other metabolic processes.

The term ‘vitamin’ was coined by Funk. Casimir Funk, a Polish biochemist, introduced the term in 1912 to describe essential organic compounds necessary for human health. Funk’s research focused on identifying and isolating these substances, initially referred to as “vital amines,” as they were believed to be nitrogen-containing compounds vital for life.
Although it was later discovered that not all vitamins were amines, Funk’s term ‘vitamin’ persisted and became widely adopted to describe these essential micronutrients. His pioneering work laid the foundation for the study of vitamins and their role in preventing deficiency diseases, leading to significant advancements in nutrition science and public health. Funk’s contributions revolutionized our understanding of the importance of vitamins in maintaining health and underscored their significance in human nutrition and well-being.
