4 Most Common Body Compounds (Biology)
Carbohydrates are the molecules we call sugars and starches. Sugars contain energy, which is important for carbohydrate to produce bonds, creating the molecules.
Dehydration synthesis is the joining of two sugars. When this happens water is lost from the molecule. The way this becomes possible is two or more monosaccharides are combined to form larger molecules. The chemical bond linking the two molecules together is formed by the -OH (hydroxide ion) groups present in each molecule. When the bond completes the transformation the water molecule has been removed.
Polysaccharide is the forming of very large molecules joined together by monosaccharides or simple carbohydrates. This is how living creatures store excess sugar. A very important polysaccharide is starch, which is how plants store their sugar, like potatoes and grains.
Hydrolysis means the reversing of dehydration synthesis. This refers to no more losing water. Hydrolysis means water splitting, which is an appropriate name because a molecule of water is consumed by the chemical reaction that splits the bond between the adjacent monosaccharides.
Lipids are organic compounds that are waxy and oily. They have three major roles: storing energy, forming biological membranes, and certain ones are used as chemical messengers.
Saturated lipids have single bonds. Lipids made from saturated fatty acids are also referred to as saturated. Unsaturated lipids have double bonds. Both animals and plants use lipids to store energy.
Sterol has an important role of building cells and carrying messages from a part of the body to another part. The most common sterol is cholesterol. Phospholipid is a molecule consisting of parts that dissolve well in water.
Proteins are organic compounds containing nitrogen, as well as, carbon, hydrogen,...
