Vitamin A is a flake crystal that has a melting temperature of 62-64 degrees Celsius and a boiling temperature of 120-125 degrees Celsius (0.667Pa). It is easily soluble in organic solvents or oil, but not in water. Vitamin A is stable in alkaline and acidic conditions. It has a good thermal stability. Antimony trichloride causes a blue reaction, and can be damaged by air and ultraviolet light. Coexisting with Vitamin C can protect it.
Vitamin A is found in animal foods as free aldehydes and esters. It is also abundant in dairy products, liver, fat and protein. Vitamin A does not exist in plants, but its precursor is found in vegetables like carrots and tomato. Animals can convert it into Vitamin A after being absorbed.
Vitamin A plays a vital role in maintaining human growth, development and reproduction. It also helps maintain the integrity of cell membranes and is important for visual processes. Retinal is continuously metabolized in the body and must be replenished by Vitamin A.
Vitamin A is essential for the structure and function upper and lower cell structures. Its deficiency may cause dryness, inflammation and even blindness in the cornea and conjunctiva. The respiratory epithelium can be damaged, causing respiratory infections, hair fall, and delayed development in infants.
