А сама я вот на это глаз положила. Но пока не решилась.

А что повлияло?

Еще одно мнение:
humans do NOT require more than 1 gram, 1/5th of a teaspoon, of Omega-3's per day since more than 4 or 5 grams of ANY polyunsaturated oil destabilizes our cell membranes and makes them too thin, fluid & flexible, weak & leaky. Humans need more of the firmer saturated fats for optimum cell membrane conformation since we make our own body heat and at 98.6 are just 1.4 degrees from 100F. See the Wiki article re Homeoviscous Adaptation, deep sea arctic fish can change the oil in their cell membranes to incorporate more omega-3 so they don't freeze up like a car in winter, then replace the omega-3's with saturated fats when they move to warmer waters around the equator. ONLY deep sea cold water fish require high levels of omega-3's, humans don't, humans actually require 2 to 3 grams per day of natural, unadulterated, unprocessed organic, cold extracted CIS omega-6 linoleic acid based on human tissue requirements. Human skin is all omega-6, there's NO omega-3's in skin and O-3 will not protect from melanoma, and the arterial system is also all omega-6 tissue.

Activity – Stability – Flexibility Relationships of the biochemistry

For the non scientist: cold shrink proteins and alters their function to meet new demands.  Cold requires that we add PUFA’s to our cell membranes and alteration of protein folding to accomplish biochemical reactions.

Geek View:Low temperatures tend to improve the compactness of a proteins by limiting the ‘breathing’ of the structure corresponding to micro-unfolding processes. Therefore, at low temperatures, a mesophilic protein will lose the mobility required for its catalytic activity. What this means is that as it get colder we need to make the molecules more flexible to work in the cold. This means at extremes, physic laws (QM) do some strange things to our biochemistry. The current accepted hypothesis (Gerday et al. 1997; Zavodszky et al. 1998) suggests that psychrophilic enzymes have to increase their plasticity in order to perform catalysis at low temperatures. The enhanced plasticity being generated by the generally low stability of the protein structure. This balance between flexibility and stability represents one of the crucial points in the adaptation of a protein to environmental temperature swings. We now know in 2012 that cell membrane signaling is the single most important feature of cold adaptation. The colder it is the more omega 3′s are need for cell membrane signaling. The warmer it is the less omega three we need in cells to signal. This implies that in warm adapted mammals omega 3′s might have deleterious effects. They do.

It has been shown that the psychrophilic alpha-amylase from Pseudoalteromonas haloplanktis has reached the lowest possible stability of its native state (Feller et al. 1999). This has been notably demonstrated by DSC, which is a powerful tool to investigate the thermal unfolding of proteins. Differential Scanning Calorimetry (DSC) is unsurpassed for understanding the stability of biological systems.  DSC directly measures heat changes that occur in biomolecules during controlled increase or decrease in temperature, making it possible to study materials in their native state. I  also saw this some remnant effects in my example that opened this blog. Not only was oxygen binding tighter than normal but there had to be changes in the hemoglobin molecules to make this physical chemistry happen. It appears that there are some unusual effects in the chemical bonds and in atoms on a sub atomic level that allow biochemistry to adapt. These adaptations are also present in humans when they are cold adapted. I mentioned earlier in the CT series that mammals have a unique way of altering their own cell membrane structures in anticipation of cold. My theory had predicted that because of the physics of the chemistry at cold I am describing to you here. It is clear PUFA additions make the cell membranes more fluid in cold so their signaling can work well. This has bigger implications for the optimal fuel for mammals in cold. The more extreme the environment the more flexibility the cell membrane needs. This is why omega three fats would be favored over omega six fats in mammals who are live in the coldest environments. The reason is that omega three fats have more unsaturated bonds that allow for more fluidity in the cell membranes for ideal signaling. Take a guess where the omega three sources come from? The deep ocean. It appears evolution is using form for function ideally, once again.  The best natural source is Krill and other fish that support huge ecosystems in our polar seas for these mammals. Krill oil use makes a lot more sense for warm adapted mammals than fish oil does because of its stability in warm temperatures. This is a major down side to Fish oils.

Non scientist and geek unite: The best food source then for a cold adapted mammals biochemistry would be a ketogenic paleolithic diet that has a high omega 3 content.
