Is it clear on whether fat deposition in muscle tissue has negative or positive effects for overall health? Does this reduce visceral fat? Negative effects on performance? Any other follow up?

Actually fats are not much more complex than sugar molecules, if at all. Fats are essentially just 3 straight chain hydrocarbons that may or may not be saturated. Once lipolysis begins it is actually a faster process than breaking down glycogen and sugar. It’s just the body will delay initiating the process because our body prioritizes the use of glucose over fats for energy for various reasons.

Google a picture of triglycerides and a picture of glycogen and see which is more complex.

Very cool. I honestly believe this is just a person mentally visiting other parts of their brain and not being able to understand that they’re experiencing so their brain fills things in with something they know to be diminutive. Then they talk to their different selves before moving on.

Bonds forming is an indication of a chemical reaction. A mixture does not create new bonds or break bonds. Sugar, for example, just mixes in with water. Each sugar molecule is surrounded by water molecules and becomes an aqueous solution. These are not “bonds” but rather intermolecular forces that hold the mixture together the way it is.

Where does myelination fit in here?

In general, like in a lab setting, we would regard CH4 as a non-polar molecule overall. However, what has been agreed upon by the powers that be is that technically each individual C-H bond is in fact polar because of the difference in electronegativity of carbon and hydrogen. And technically this is a correct statement, no matter how small of a difference it might be.

It must also be recognized that there is a sliding scale of polarity that ranges from slightly polar like the example given, to very polar such as in water. To be fair this is getting very technical and for all intents and purposes, no one really talks about pure hydrocarbons as being polar molecules.

In addition to what the other guy said, I teach AP chemistry and right now what is being taught at the advanced high school level is that if there is a molecular bond between elements that are not the same, then it is polar due to the inherent difference in electronegativity. For instance H2 or a carbon carbon bond would be non polar examples.

Also, what was not stressed in the other comment is the shape of the molecule. Carbon dioxide is linear

O=C=O so while the oxygen-carbon bonds are each polar due to O high electronegativity, the shape of the molecule will cancel out because of opposing pull of electrons. Same goes with something that is tetrahedral with polar bonds. The symmetrical shape cancels out the dipoles. So a shape that is not symmetrical such as the bent shape of water or ammonia, will have polar bonds AND be a polar molecule.
