Study Notes
Functions of Carbohydrates
- Carbohydrates are the most abundant source of energy, providing 4 calories per gram
- They serve as precursors for many organic compounds, such as fats and amino acids
Biomolecules
- Biomolecules are chemicals or molecules present in living organisms
- The sum total of different types of biomolecules, compounds, and ions present in a cell is called the cellular pool
- Biomolecules are compounds of carbon, making carbon the most versatile and predominant element of life
Major Complex Biomolecules
- Proteins: composed of amino acids, providing basic structure and function of cells
- DNA: composed of deoxyribonucleotides, carrying hereditary information
- RNA: composed of ribonucleotides, involved in protein synthesis
- Polysaccharides: composed of monosaccharides, serving as a storage form of energy
- Lipids: composed of fatty acids and glycerol, serving as a storage form of energy to meet long-term demands
Carbohydrates
- Carbohydrates are the most abundant organic molecules in nature
- They serve as a storage form of energy
Storage Polysaccharides
Starch
- Starch is the carbohydrate reserve of plants and the most important dietary source for animals
- It is found in high concentrations in cereals, roots, tubers, and vegetables
- Starch is a homopolymer made up of glucose units, also known as glucan
- It consists of two polysaccharide components: amylose and amylopectin
Glycogen
- Glycogen is the carbohydrate reserve in animals, also referred to as animal starch
- It is found in high concentrations in the liver, muscles, and brain
- It is also found in plants that do not have chlorophyll, such as yeast and fungi
- Glycogen is composed of glucose units, serving as a storage form of energy
