Plant sources of beta-carotene are not as well absorbed as the animal sources of vitamin A listed in the chart, but they are still an important source of this vitamin. Dark orange and green vegetables and fruit, including carrots, sweet potatoes, spinach, cantaloupe, and kale are excellent sources of beta-carotene.itamin A is a family of fat-soluble compounds that play an important role in vision, bone growth, reproduction, cell division, and cell differentiation. Vitamin A is important for healthy bones.
In chemistry, an alcohol is any organic compound in which the hydroxyl functional group is bound to a saturated carbon atom. The term alcohol originally referred to the primary alcohol ethanol, which is used as a drug and is the main alcohol present in alcoholic beverages. The suffix -ol appears in the IUPAC chemical name of all substances where the hydroxyl group is the functional group with the highest priority; in substances where a higher priority group is present the prefix hydroxy- will ap
Alcohols are biomolecules that contain at least one hydroxyl group (RâOH). The simplest of all oxygen-containing functional groups, hydroxyl groups add polarity to organic molecules because of the strong electronegative nature of oxygen atoms.Therefore, unless the remainder of an organic molecule is very large and nonpolar, most alcohols dissolve in water by forming hydrogen bonds.lthough it may be confusing, carbonyl and carboxyl functional groups (RâCOOH) have similar names for a reason. A carboxyl group contains both a carbonyl group and a hydroxyl group, bonded to the same carbon atom. The name carboxyl derives from combining these two terms, carbonyl + hydroxyl = carboxyl.
