Write two groups of vitamins and describe with example
Group 1: Fat-soluble vitamins
1. Vitamin A: This vitamin is important for maintaining healthy vision, skin, and immune function. It can be found in foods such as carrots, sweet potatoes, spinach, and liver. An example of Vitamin A is Beta-carotene, which is converted into Vitamin A in the body and gives carrots their vibrant orange color.
2. Vitamin D: It is crucial for bone health as it helps the body absorb calcium. Sunlight is a great source of Vitamin D, and it can also be found in fatty fish like salmon, fortified dairy products, and egg yolks. An example of Vitamin D is Cholecalciferol, which is produced in the skin when exposed to sunlight and is also found in some supplements.
Group 2: Water-soluble vitamins
1. Vitamin C: It acts as an antioxidant, supports the immune system, and helps in collagen production for healthy skin. Citrus fruits like oranges, strawberries, kiwis, and bell peppers are excellent sources of Vitamin C. An example of Vitamin C is Ascorbic acid, which is widely used in dietary supplements.
2. B Vitamins: This group consists of several vitamins, including B1 (thiamine), B2 (riboflavin), B3 (niacin), B6 (pyridoxine), B9 (folate), and B12 (cobalamin). B vitamins play essential roles in energy production, brain function, and red blood cell formation. They can be found in a variety of foods like whole grains, eggs, meat, legumes, and leafy greens. An example is Vitamin B12, which can be obtained from animal products, such as meat, fish, eggs, and dairy. It is crucial for nerve function and DNA synthesis.
