105 examples of Acids in a sentence
It has the chemical sequences of amino
which says, "This is how to build the structure.
And you flip it over, and it's the amino
with the pH at which they have different charges.
And this one happens to be a good source of all 20 amino
And somehow these amino
are combined, and life begins.
And they had a look at what was in the soup, and they found amino acids, but nothing came out, there was no cell.
So I'm highlighting just a few words and saying definitions like that rely on things that are not based on amino
or leaves or anything that we are used to, but in fact on processes only.
Because if we can, maybe we have a chance of actually discovering life somewhere else without being biased by things like amino acids."
We could use amino acids, we could use nucleic acids, carboxylic acids, fatty
So that we actually, to test this idea, first took a look at amino
and some other carboxylic
Here is, in fact, what you get if you, for example, look at the distribution of amino
on a comet or in interstellar space or, in fact, in a laboratory, where you made very sure that in your primordial soup, there is no living stuff in there.
Of course, there is still glycine and alanine, but in fact, there are these heavy elements, these heavy amino acids, that are being produced because they are valuable to the organism.
And it is detectable not just in amino
I can tell you indeed it is, because this type of spectrum, just like what you've seen in books, and just like what you've seen in amino acids, it doesn't really matter how you change the environment, it's very robust, it's going to reflect the environment.
They're very repetitive, and they're very rich in the amino
glycine and alanine.
So what you're seeing here is the one letter abbreviation for amino acids, and I've colored in the glycines with green, and the alanines in red, and so you can see it's just a lot of G's and A's.
And this is a game where individuals can actually take a sequence of amino
and figure out how the protein is going to fold.
These micro-machines, which are the envy of nanotechnologists the world over, are self-directed, powerful, precise, accurate devices that are made out of strings of amino
Life brought biosynthetic factories that are powered by sunlight, and inside these factories, small molecules crash into each other and become large ones: carbohydrates, proteins, nucleic acids, multitudes of spectacular creations.
And they used the chemical energy produced to draw CO2, carbon dioxide, out of the atmosphere and use it to build sugars and proteins and amino acids, all the things that life is made of.
The basic building blocks of life aren't unique to Earth: amino
have been found in comets, complex organic molecules in interstellar dust clouds, water in exoplanetary systems.
Well, it means that just as the English language is made up of alphabetic letters that, when combined into words, allow me to tell you the story I'm going to tell you today, DNA is made up of genetic letters that, when combined into genes, allow cells to produce proteins, strings of amino
that fold up into complex structures that perform the functions that allow a cell to do what it does, to tell its stories.
It would be able to make new proteins, proteins built from more than the 20 normal amino
that are usually used to build proteins.
So of course, with natural cells, you can only get them to make proteins with the natural amino acids, and so the properties those proteins can have, the applications they could be developed for, must be limited by the nature of those amino
that the protein's built from.
So here they are, the 20 normal amino
that are strung together to make a protein, and I think you can see, they're not that different-looking.
So can we get our semisynthetic organism to make proteins that include new and different amino acids, maybe amino
selected to confer the protein with some desired property or function?
What if we could make proteins with new amino
with things attached to them that protect them from their environment, that protect them from being degraded or eliminated, so that they could be better drugs?
So could we take those molecules and make them parts of new amino
that, when incorporated into a protein, are guided by that protein to their target?
Doing that would be really difficult or impossible to do with the normal amino acids, but not with amino
that are specifically designed for that purpose.
Omega-3 fatty acids, present in fatty fish, like salmon, will increase the production of these new neurons.
The three long chains on the right are called fatty acids, and it's subtle differences in the structures of these chains that determine whether a fat is, let's say, solid or liquid; whether or not it goes rancid quickly; and, most importantly, how good or how bad it is for you.
