Question

class discussions about categories of biochemical molecules

Answer 1

Biochemical compound contains carbon and is found in living beings and are involved in every process of life. These compounds are classified into four types namely, carbohydrates, proteins, fats and nucleic acids.

• Carbohydrates are macromolecules made up of carbon, oxygen, and hydrogen. Carbohydrates provide energy to the body. Examples of carbohydrates include glucose, starch and cellulose.
• Proteins are long chains of amino acids, which are more complex than carbohydrates and contain carbon, oxygen, hydrogen, nitrogen, and sulfur. Proteins do most of the work in cells and are required for the structure and regulation of the body's tissues and organ, via functioning as an enzyme or hormone.
• Lipids are small, hydrophobic molecules built from fatty acids. Lipids constitute of carbon, oxygen and hydrogen. They're not soluble in water, but can be dissolved in organic solvents. Lipids play many roles in cells, including serving as energy storage, constituents of membranes, hormones, vitamins etc.
• Nucleic acids are biological polymers made from nucleotides, and are the most complex of the classes of biochemical compounds. They contain carbon, hydrogen, oxygen, nitrogen amd phosphorus. Nucleic acids are involved in the storage and expression of genetic information. Examples include DNA and RNA.
