Silk fiber:
Silk is a natural protein fiber that is produced by the silk moth larvae to create cocoons. It is known for its strength, smoothness, and lustrous appearance. The composition of silk fiber includes:
1. Proteins:
Silk fiber is primarily composed of proteins. The main protein present in silk is called fibroin, which makes up around 75-90% of the fiber. Fibroin is a strong and flexible protein that gives silk its unique properties.
2. Lipids:
Silk also contains lipids, which are organic compounds that are insoluble in water. These lipids are found in the outer layers of the silk fiber and help to protect and lubricate the fiber.
3. Carbohydrates:
While silk fiber is mainly composed of proteins, small amounts of carbohydrates may also be present. These carbohydrates are typically found in the form of sugars and are present in the silk glands of the silk moth larvae.
4. Fats:
Fats, which are a type of lipid, may also be present in silk fiber. Fats are important for providing energy and insulation, and they may contribute to the overall composition of silk.
In conclusion, the correct answer is B: proteins. Silk fiber primarily consists of proteins, with small amounts of lipids, carbohydrates, and fats also present.
