In summary, the conversation discusses the reason for the diversity of molecules found in organic bodies, specifically in wool fat. It is explained that there is no defined purpose or pre-thought behind the production of these molecules, but rather they are a result of past evolutionary success. The conversation also addresses the misconception that nature only produces what is necessary for survival and explains that what remains in the genome are traits that do not interfere with survival. The possibility of lanolin molecules having photosynthetic features is also mentioned, which could potentially give them a purpose in regulating temperature for the animal's skin.

Hello,

Is there anywhere a reference to get an idea, why wool fat consists of over 200 different molecules?

Is there some sort of a general law or ruling, like the Darwin's evolution, that nature produces nothing more and nothing less as what is required for the propose?

If so, how is such a diversity of molecules produced in organic body and for what propose(s)?

Thanks for looking.

This is worded to reflect your approach to your question.

There are many more than 200 molecules in a single cell in your hand.

Organic bodies do not have purpose-driven chemical reactions. Organic bodies are following a blueprint in the genetic material. There is no defined purpose or pre-thought behind it. Humans assign meaning and purpose there because we work that way mentally. You assign meaning. Sheep epidermal glands secrete a given molecule (pick one) because somewhere long ago some sheep ancestral animals that secreted molecule A did better and had more baby animals than the beasties that secreted molecule B.

Those conditions that favored molecule A may not even exist today but the sheep's oil glands still produce molecule A. Along with all of the others.

Mammals secrete sebum (skin oils) - Human sebum, secreted by sebaceous glands mostly on the face, is composed of:
triglycerides, wax esters like squalene and various sloughed off cellular materials. Sebum can break down because of skin bacterial action, creating even more compounds. So. Sheep are mammals just like us.

That's a misconception that perhaps we can clear up for you. What remains in the genome and continues to be expressed phenotypically are not just traits that aid survival, but traits that don't interfere with survival. The reason that people continue to be born with poor eyesight, appendixes, and wisdom teeth is that we've found work-arounds to these pesky issues. If we weren't so stinkin' smart, these inconveniences would have probably been selected out a long time ago.

Granted, parsimony is a welcomed friend of natural selection, but what sticks around is what works, whether it's a sloppy fix or a parsimonious one.

Lanolin and Energy

Thanks for your contributions. Why have i come up with the question of propose of these lanolin molecules? There are some signs as energetic measurements, that these fat molecules may have photosynthetic features. Remember the day-night cycle of photosynthesis involving CO2 and H2O, accompanied with energy consumption and release based on glucose for instance. This would give them not only a meaningful propose as cooling the animal skin during the day and warming it in the night. Is such a cycle possible based on the molecules involved?

Hello,

The reason for the diversity of molecules in lanolin, or wool fat, is due to the complex nature of the substance and its function in the sheep's body. Lanolin is produced by the sebaceous glands in the skin of sheep and is used to protect and nourish their wool. As a result, it needs to have a wide range of properties to effectively perform its function.

Lanolin is composed of a variety of fatty acids, alcohols, and esters, each with their own unique chemical structure. These molecules work together to create a complex mixture that is able to provide waterproofing, lubrication, and insulation for the sheep's wool. This is essential for the sheep's survival in harsh environments.

There is no specific law or ruling that dictates the number of molecules in lanolin or any other organic substance. Instead, the diversity of molecules is a result of natural selection and adaptation. Over time, the sheep's body has evolved to produce a complex mixture of molecules that best serves its needs.

In conclusion, the diversity of molecules in lanolin is a result of its important function in the sheep's body and its evolution over time. I hope this answers your question. Thank you for your interest in this topic.
 

1. What is lanolin and why is it important?

Lanolin is a waxy substance produced by the sebaceous glands of sheep. It is an important component of wool and plays a crucial role in protecting sheep's skin and coat from external factors.

2. How many molecules make up lanolin?

Lanolin is composed of over 200 molecules, making it a complex mixture. These molecules include fatty acids, esters, alcohols, and sterols.

3. How is lanolin extracted from wool?

Lanolin is extracted from wool by washing the raw wool in a solvent, such as petroleum ether, to remove impurities and dirt. The lanolin is then collected from the solvent through a process called saponification.

4. What properties make lanolin beneficial for skincare?

Lanolin has emollient and moisturizing properties, making it an excellent ingredient for skincare products. It helps to hydrate and soften the skin, as well as protect it from dryness and external irritants.

5. Is lanolin safe to use in skincare products?

Lanolin is generally considered safe for use in skincare products, but some people may have an allergic reaction to it. It is important to patch test any new products containing lanolin before using them on a larger area of the skin.
