Water!!! :D

Water is a Dihydrogen oxide. This means that it doesn't have any odor or taste. Water can be benign or lethal. Water can be very deadly, but also very helpful. we use water in our everyday life. Without water there wouldn't be life.

What's Macromolecules?!

Macromolecules are large molecules. There are four groups of macromolecules; lipids, carbohydrates, nucleic acid, and proteins.

The Macromolecules Song


Lipids are another word for fats. These are a type of macromolecules. There are two types of lipids; unsaturated and saturated fats. Unsaturated fats have at least one double bond within the fatty acid chain. These fats can be non-solid. Oil is an example of unsaturated fat.
Saturated fat have a single bond within the fatty acid chain. They have no double bonds between the individual carbon atoms of the fatty acid chain. These fats are usually solid. Butter is a saturated fat.


Carbohydrates are a group of organic compounds. Its made up of hydrogen and oxygen. They include sugars, cellulose, and starch. Carbohydrates are usually broken down for energy in animals and human beings bodies. There are four types of carboydrates. Polysaccharides, monosaccharides, disaccharides, and oligosaccharides.


Nucelic acids are complex organic substance. They are Present in all living things. RNA and DNA are the types of nucelic acids. RNA stands for ribonucleic acid. This is a nucleic acid molecule similar to DNA but containing ribose rather than deoxyribose. DNA stands for deoxyribonucleic acid. It's a nucleic acid that carries the genetic information in the cell and is capable of self-replication and synthesis of RNA.


Proteins are large biological molecules, or macromolecules. They consist of one or more chains of amino acid residues. Meats, eggs, dairy, seeds, and nuts are examples of proteins. It is the most abundant substance in your body. Proteins have many functions. It's used to help growth in hair and nails, it stores energy, and also helps with our blood.


Enzymes are a type of protein that promote chemical reactions. it is a substance produced by a living organism that acts as a catalyist. To bring about a specific biochemical reaction.
