What molesculs does carbohydrates consist of
Carbohydrates are important macromolecules that consist of carbon, hydrogen, and oxygen in a 1:2:1 ratio (can be written as C n (H 2 O) n). Carbohydrates are organic compounds organized in the form of aldehydes or ketones with multiple hydroxyl groups coming off the carbon chain. Carbohydrates have the general molecular formula CH 2 O, and thus were once thought to represent hydrated carbon. However, the arrangement of atoms in carbohydrates has little to do with water molecules. Starch and cellulose are two common carbohydrates. Other carbohydrate molecules are very large (polysaccharides such as starch and cellulose). Carbohydrates are: 1  a source of energy for the body e.g. glucose and a store of energy, e.g. starch in plants. 2  building blocks for polysaccharides (giant carbohydrates), e.g. cellulose in plants and glycogen in the human body. 1 The cell walls of bacteria are mainly made up of polysaccharides (types of carbohydrate). 2  Cellulose (a type of carbohydrate) makes up most of plant cell walls. 3  Carbohydrates are linked to many proteins and lipids (fats), where they are vitally involved in cell interactions. Carbohydrates contain three major categories of molecules: monosaccharides (or simple sugars), disaccharides, and polysaccharides. 1. Monosaccharides: This group, also known as simple sugars, is the simplest carbohydrate form. Starch and cellulose are two common carbohydrates. Both are macromolecules with molecular weights in the hundreds of thousands. Both are polymers (hence  polysaccharides ); that is, each is built from repeating units, monomers, much as a chain is built from its links. Plants synthesize two types of polysaccharides, starch and cellulose. The glycosidic bonds between glucose units in plant starch are similar to those in animal glycogen. Accordingly, starch molecules are structurally similar, forming compact coils, and play a similar role in energy storage for plants. Carbohydrates have the general molecular formula CH 2 O, and thus were once thought to represent hydrated carbon. However, the arrangement of atoms in carbohydrates has little to do with water molecules. They are often called sugars. Other carbohydrate molecules are very large (polysaccharides such as starch and cellulose).
