Frequently Asked Questions | FAQs
What is amino acid with example?
Amino acids are organic compounds that are the building blocks of proteins. They are made up of an amino group (-NH2), a carboxyl group (-COOH), and a side chain (R-group) that varies for each different amino acid. There are 20 different types of amino acids commonly found in nature, each with a unique chemical structure and properties
What is the composition of wool?
Wool is a natural fiber that is composed mainly of protein, specifically a protein called keratin. Keratin is a fibrous protein that makes up the outer layer of skin, hair, and nails in animals. In addition to keratin, wool also contains small amounts of lipids, minerals, and water.
The specific composition of wool can vary depending on the animal it comes from, the breed of the animal, and the environmental conditions in which the animal was raised. Generally, wool is made up of approximately 65-70% keratin protein, 12-25% water, 1-3% lipids, and trace amounts of minerals such as sulfur, potassium, and sodium. The chemical composition of wool gives it unique properties, such as its ability to absorb moisture, resist wrinkles, and provide insulation.
