The Four Macromolecules include Carbohydrate, Lipids, Nucleic acid, and Protein.
Carbohydrate are
Any of a group of organic compounds that includes sugars, starches, celluloses, and gums and serves as a major energy
source in the diet of animals; they are produced by photosynthetic plants and contain only carbon, hydrogen, and oxygen, usually
in the ratio.
Lipids:
Any of a group of organic compounds, including the fats, oils, waxes, sterols, and triglycerides, that are insoluble
in water but soluble in nonpolar organic solvents, are oily to the touch, and together with carbohydrates and proteins constitute
the principal structural material of living cells.
Nucleic acid:
Any of a group of complex compounds found in all living cells and viruses, composed of purines, pyrimidines, carbohydrates,
and phosphoric acid. Nucleic acids in the form of DNA and RNA control cellular function and heredity.
Protein:
Any of a group of complex organic macromolecules that contain carbon, hydrogen, oxygen, nitrogen, and usually sulfur and are
composed of chains of alpha-amino acids. Proteins are fundamental components of all living cells and include many substances,
such as enzymes, hormones, and antibodies, that are necessary to the functioning of an organism. They are essential in the
diet of animals for the growth and repair of tissue and can be obtained from foods such as meat, fish, eggs, milk, and legumes.
