In the spirit of self-expression, this is a short article on what we think about the genetic code and its relation to lipids. The concept, of course, has been around for many years, but it is not well-known in the scientific community. It’s also difficult to explain without extensive research into human evolution, where we are still very close to the origin of life.
One thing you can say about DNA is that it doesn’t have a lipids molecule attached to it. That makes it a living organism instead of our dead skeletons in jars.
There are lipids molecules on every cell in our bodies, but they are not essential for life except in scarce circumstances . . .
One interesting fact that might help explain lipids: they all have the same general structure. Though, they do have some slight differences in their chemical makeup, some lipids may be more soluble than others, and some may be more insoluble than others. When you look at a molecular diagram of an animal cell, you will often see several different structures with very similar names but slightly different chemical properties. This is because they have been made by one cell and then used by other cells as building blocks for their unique structures and functions.
For example, adenine (A) is used by all nucleoid cells for making RNA; guanine (G) comes from myoglobin; cytosine (C) comes from nucleic acids; uracil (U) comes from purines and thymine (T).
So now let’s look at how lipid molecules are made:
Lipid molecules consist of two rings or rings and two fatty acid chains attached through carbon atoms . . . The fatty acids are directly or indirectly linked to oxygen atoms via double bonds at C=C or C=O bonds, respectively .
The simplest type of lipid molecule consists of just three fatty acids linked by a single glycerol molecule into an “oil-like” structure called a triacylglycerol . These triacylglycerols form when glycerol molecules are incorporated into triglycerides  . Then when glucose enters the bloodstream, they include free fatty acids, which attach themselves to phospholipid surfaces forming phospholipid bilayers , which give rise to cholesterol . Some macro M
2. What is DNA?
DNA has long been known to play a role in human evolution, but the origins of this ancient molecule are still debated.
But discoveries suggest that DNA may also play important roles in today’s complex world of molecules and chemical reactions.
DNA is a unique molecule composed of four basic building blocks:
- Nucleotides are the chemical building blocks that comprise the genetic code.
- Amino acids are the building blocks for proteins.
- Sugar molecules are called ribose.
- Phosphate groups.
Each of the four is essential for life and functions as both an energy source (ATP), an information carrier (check out my previous blog post on ATP), and a molecular chaperone (check out my last blog post on molecular chaperone).
3. The structure of DNA
DNA is the blueprint of all life on earth, a molecule containing an entire library of information created by living organisms.
However, it’s not to be taken lightly because it’s one of the most important things we share with animals and plants. DNA is responsible for everything from making you who you are (referring to your genes) to determine how long you’ll live (your genotype).
Scientists have studied human DNA, particularly its structure, since the 1960s to understand how it works and what makes us unique. They discovered that three different types of nucleotides make up our genetic material or “DNA”— Adenine (A), Thymine (T), and Cytosine (C). They also discovered that A, or adenine, can be joined to T, or thymine, forming adenine cytosine and vice versa.
Adenine cytosine is an unstable chemical compound because it breaks down quickly when exposed to heat — such as from light — so A can neither form nor be attached to T. This makes A unattractive for joining with T because neither molecule would remain together for long.
The second type of nucleotide is called uracil; it creates a double sugar structure leading to its instability when exposed to heat or light. Thus, it cannot join with another nucleotide without breaking apart during this process. This means T can only become attached to C through uracil, which creates a stable structure as opposed to adenine cytosine, which forms a bond with uracil causing A/T/*C^T^C^T^A loss of stability.
The third type of nucleotide increases stability by creating two bonds between bases instead of just one; this means C can quickly join with C resulting in C^A’s loss of strength compared to Ad/T*C^A, which results in the formation of C^T^C^A by having two bonds between bases instead of one giving rise to D/T*D^D loss at the expense of stability.
4. The role of lipids in DNA
In an article titled “The role of lipids in DNA,” researchers found that the two genetic phenomena were not exclusive. The presence of lipids in a DNA strand has been demonstrated to be important not only in the synthesis of proteins but also in stabilizing and protecting the strands from damage.
5. The benefits of having lipids in DNA
The answer to this question is yes. DNA has lipids in it. Lipids are the building blocks of all life; as such, they can be found in all living things – from bacteria to humans, dogs to people.
So we’ve seen that Lipids are a part of DNA, but why is that important?
For one thing, Lipids give DNA its structure. The backbone of DNA is a long chain of simple sugars (sugar molecules) but also hydrophobic molecules that can be thrown into the bloodstream and fill watery tissues with lipid-rich water so that they can stay liquid and not dissolve into plasma (which would mean no more oxygen).
These globular molecules stick together and form protein complexes called phospholipid bilayers. The protein structures inside the bilayer then work together to make enzymes and other parts of cell machinery function by aligning the inside surface of the bilayer with outside surfaces like proteins in a membrane.
The other reason we see lipids in DNA is that they’re both made up of carbon atoms, which are just as hard as metals. Carbon compounds contain six hydrogen atoms (abbreviated H), whereas Lipids only have 3 (abbreviated H2). So when you see two or more carbon atoms bonded together, you get a compound called an ester – chemical bonds between two different chemicals. One chemical may be an acid, while another may be a base.
This makes esters so useful for storing energy or as chemical precursors for new compounds such as amino acids or nucleotides, like how sugar is used for fuel by our bodies.
To sum it up: 1) fats make up lipids; 2) fats can connect to other fats; 3) fats can connect to other Fats; 4) Fats connect to other Fats; 5) Fats connect to Hitos; 6) Hitos try hard not to do this; 7) Hitos try hard not to do this; 8) Hitos try hard not to do this; 9) Hitos try hard not to do this; 10-11: Carbohydrates are made up of simple sugars (sugar molecules); 12-14: Carbohydrates have lots of sugars attached; 15-16: Many carbohydrates have lots -many- sugars attached.’
6. The drawbacks of having lipids in DNA
There are several myths surrounding the role of lipids in DNA. What is even more impressive is that we can’t even agree on whether there is a correlation between lipids and DNA—a study in last week’s topic of Science markets with this topic.
They hypothesized that the presence of lipids in DNA is linked to a higher risk of cancer because the lipid peroxidation process may be related to various forms of cancer. Lipid peroxide, formed when free radicals attack the lipid molecules, is a known carcinogen, and its presence could be one reason for cancer development.
The authors recruited 14,615 people (ages 40-69) from three countries: People in northern Alaska (USA), Greenland (Denmark), and Papua New Guinea (PNG). They also recruited 572 people from two other countries: People from China and Russia. Questionnaires interviewed the participants about their diet, lifestyle, medical history, family history, and treatments. In addition, they filled out questionnaires covering things like physical activity and social contacts.
The researchers also measured total cholesterol and triglyceride levels using ultrasensitive measurement techniques.
The results showed no relationship between total cholesterol or triglyceride levels and disease risk factors such as smoking or obesity…..
A study published last month involved two groups of subjects:
One group was given an informative booklet about the role of lipids in DNA; both groups were given video-based information about the connection between lipid peroxidation and cancer; both groups were given an informational booklet on how to reduce their risk for disease; both groups were given information on how to lower their risk for infection by increasing physical activity; none was given information on reducing their risk for disease by reducing smoking.
The second group was asked to read a fictional book written by someone else who had died from a form of cancer….
The results showed that none of the subjects who received information on reducing their cancer risks had become smokers or alcoholics. In contrast, those who read fiction had become smokers or alcoholics….
