Silk Proteins facts

While investigating facts about Silk Proteins For Hair and Silk Proteins For Skin, I found out little known, but curios details like:

It is common for spiders to eat their own web daily to reuse the silk proteins.

how can goats produce spider silk proteins?

There is a goat at Utah State University with DNA from a spider so it will produce spider silk protein when milked.

What proteins make up spider silk?

In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what do silk proteins do for hair. Here are 20 of the best facts about Silk Proteins For Biomedical Applications and Silk Protein Shampoo I managed to collect.

what are silk proteins?

1. Some spiders are master recyclers. Orb-weavers remove their webs every morning by eating the silk. This way, protein from the silk is never wasted. They hide from predators all day and make a new web at night. I saw this myself this morning at on my balcony!

2. A goat in Utah was implanted with spider genes as an embryo to produce spider silk proteins in her milk which is used to make "bio-steel", a material which is stronger than Kevlar.

3. One attempt to synthesize spider silk consisted of transferring the gene to goats. The goats’ milk then contained the spider silk protein.

4. It is common for spiders to eat their own web daily to recoup some of the energy used in spinning. The silk proteins are thus recycled.

5. Kraig Biocraft Lab found a way to use spider-silk to make bulletproof material. They took the silk proteins, stronger thank steel and Kevlar, from spiders, introduced the genetic material into the friendly, kumbaya, a super-efficient silkworm which now spins out the spider-silk!

6. In 2008, the US Dept. of Defense funded a project that successfully engineered "BioSteel Goats". These goats produce milk containing the protein used to create spider silk, which researchers report as 7 to 10 times stronger than steel

7. It is common for spiders to eat their own web to recoup some of the energy used in spinning. The silk proteins are thus recycled, and as the web loses its stickiness the longer it hangs, a newly constructed web is most effective for catching spider food!

8. There are genetically modified goats, given spider genes, they produce silk proteins in their milk, which is then processed to create a synthetic silk called biosteel.

9. Scientists are making bullet-proof skin from spider silk proteins and human skin cells

10. Mopane hosts mopane worms (larvae of emperor moth) and silkworms. Mopane worm is important source of nutrients and proteins for the South African tribes. Silkworm encapsulates itself in the cocoon made of silk that is used in the manufacture of cloths among the local tribes.

Why silicon valley is ending?

You can easily fact check why silicon valley for startups by examining the linked well-known sources.

Nexia Biotechnologies developed a transgenic goat whose milk contains proteins like that of spider silk. This milk was then able to be refined into super strong bio-steel polymers.

An American farm is raising "Spider Kids". Researchers developed a way to incorporate spiders' silk-spinning genes into goats, allowing them to harvest the silk protein from the goats’ milk. - source

Silk is a natural Protein fiber, which can be woven into textiles. The protein fiber of silk is composed mainly of fibroin and is produced by silkworm larvae to form cocoons. It take about 800 cocoon to produce 1kg silk, they ate 170 kg of leaves, and can make 4 M-size men T shirt. - source

Researchers managed to develop a transgenic goat that produced milk containing spider silk proteins, which was then refined to strong biosteel polymers.

Scientists transfered the gene that produces the silk protein in spiders, into a goat. They were now able to harvest the silk-protein from the goats milk. - source

When silicon valley season 6?

Silk is the only natural fiber found in filament form. This due in part to the fact that it is made by the silk worm, an insect with specificly modified salivary glands capable of producing fibroin, an insoluble, high glycine protein

How to silk proteins?

Transgenic Nexia goats, who lactate milk with spider silk protein which can be harvested and processed.

American scientists have spliced spider DNA into goats to create goats that produce spider silk protein with their milk
