Answer:
1. Carbohydrates (CHO)
2. Lipids (fats)
3. Proteins
4. Vitamins
5. Minerals
6. Water
1.Carbohydrates (CHO):
Carbohydrates (CHO) are composed of simple sugars (i.e. glucose, fructose, galactose) and are found mainly in plants (usually stored as starches or cellulose).
2. Lipids (fats):
Lipid: Another word for "fat." (Please see the various meanings of fat.) A lipid is chemically defined as a substance that is insoluble in water and soluble in alcohol, ether, and chloroform. ... Lipids include fatty acids, neutral fats, waxes and steroids (like cortisone).
3. Proteins:
A protein is a naturally occurring, extremely complex substance that consists of amino acid residues joined by peptide bonds. Proteins are present in all living organisms and include many essential biological compounds such as enzymes, hormones, and antibodies.
4. Vitamins:
A vitamin is an organic molecule that is an essential micronutrient which an organism needs in small quantities for the proper functioning of its metabolism. Essential nutrients cannot be synthesized in the organism, either at all or not in sufficient quantities, and therefore must be obtained through the diet.
5. Minerals:
In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid chemical compound with a fairly well-defined chemical composition and a specific crystal structure that occurs naturally in pure form. The geological definition of mineral normally excludes compounds that occur only in living beings.
6. Water:
Water is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms. It is vital for all known forms of life, even though it provides no calories or organic nutrients.
