Proteins are complex macromolecules essential for various biological functions, including catalyzing metabolic reactions, DNA replication, and transporting molecules. They are composed of amino acids linked in a specific sequence, which determines their structure and function.

proteins

Nucleic acids, including DNA and RNA, are essential biomolecules that store and transmit genetic information in all living organisms. They are composed of long chains of nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base, enabling the encoding of genetic instructions for the development, functioning, and reproduction of life.

nucleic acids

Carbohydrates are organic compounds found in foods and living tissues, primarily serving as a major energy source for the body. They are classified into simple and complex forms, with their digestion and metabolism playing a crucial role in maintaining blood glucose levels and overall health.

carbohydrates

Lipids are a diverse group of hydrophobic molecules that play crucial roles in energy storage, cell membrane structure, and signaling. They include fats, oils, waxes, phospholipids, and steroids, each with unique functions and structures essential to biological processes.
