Human skin is primarily composed of proteins, lipids, and carbohydrates. These molecules contain various chemical elements, including carbon, oxygen, hydrogen, nitrogen, and sulfur.
In addition to these major components, skin also contains small amounts of minerals, nucleic acids, and water.
- Proteins make up the majority of the skin's structure, providing strength and elasticity.
- Lipids form the skin's protective barrier, helping to retain moisture and prevent the entry of harmful substances.
- Carbohydrates provide energy and play a role in cell recognition.
The exact chemical composition of skin can vary depending on factors such as age, genetics, and environmental exposure.
