Vitamin A C20H30O the discovery of vitamin A was a gradual process that took place over about 130 years. The first evidence of vitamin A's existence was in 1881, when it was observed that a small amount of a substance in milk was necessary for normal development & life. Vitamin A is a fat-soluble vitamin that is naturally present in many foods. Vitamin A is important for normal vision, the immune system, reproduction, and growth and development. Vitamin A also helps your heart, lungs, and other organs work properly. Vitamin A (retinol, retinoic acid) is a nutrient important to vision, growth, cell division, reproduction and immunity. Vitamin A also has antioxidant properties. Vitamin A helps form and maintain healthy teeth, skeletal and soft tissue, mucus membranes, and skin. It is also known as retinol because it produces the pigments in the retina of the eye. Vitamin A promotes good eyesight, especially in low light. Vitamin A is an antioxidant that protects the cornea, or outer surface, of the eye. It also maintains the function of the retina, the light-sensitive lining that converts light into nerve impulses sent to the brain. Vitamin A is especially important for scotopic (low-light) vision and color vision. Vitamin A plays a crucial role in vision by maintaining a clear cornea, which is the outside covering of your eye. This vitamin is also a component of rhodopsin, a protein in your eyes that allows you to see in low light conditions . Vitamin A also has a role in healthy pregnancy and breastfeeding.

As organic compounds, all 13 essential vitamins are primarily composed of a common set of four biological elements, with a few specific vitamins incorporating additional specialized elements for their structural & metabolic function. Fundamental Elements (CHON) Every vitamin is built from a "backbone" of four key elements that define organic life: Carbon (C): The core structural element; its presence define vitamins as "organic" substances. Hydrogen (H): Bonds with carbon & oxygen to form the complex rings & chains of vitamin molecules. Oxygen (O): Essential for the chemical reactivity of vitamins, often found in hydroxyl OH and carboxyl COOH group. Nitrogen (N): Found in several vitamins, most notably the B-complex family; in fact, the name "vitamin" originated from "life-giving amine" (nitrogen-containing compound). Specialized Elements Certain vitamins require additional elements to perform specific biological task: Sulfur (S): A critical component of Thiamin (B1), Biotin (B7) & Pantothenic acid (B5). Sulfur is necessary for the metabolic enzymes these vitamins help build. Cobalt (Co): Found exclusively in Vitamin B12, which is also known as cobalamin. Cobalt is the central atom in the B12 molecule & is essential for red blood cell production. Phosphorus (P): While not part of the initial vitamin structure, several B vitamins, such as Thiamin & Riboflavin (B2), must be "phosphorylated" (combined with phosphorus) within the body to become active coenzymes. Summary of Elemental Composition Element Group Found In Key Examples Carbon, Hydrogen, Oxygen 100% of vitamins. All essential vitamins Nitrogen B-complex vitamins Thiamin (B1), Riboflavin (B2), Niacin (B3). Sulfur Select B vitamins Thiamin (B1), Biotin (B7). Cobalt Vitamin B12 only Cobalamin May the Holy Roman Catholic Church be blessed by God the Father God the Son & God the Holy Spirit Hallelujah Hallelujah Blessed be the word of the Lord for Christ is risen Hallelujah Hallelujah peace be still in Nomine Patris et FiLii et Spiritus Sancti amen
