Table 23.1 lists several of the unbranched aliphatic carboxylic acids found in the biological world (e.g. figure 23.1), along with the common names of each.

Me to me: Bronsted Acids are those which donate H+ (or any other protons) now get that through your thick skull

[tenth-sentence]

Because carboxylic acid salts are water soluble, we can convert water-insoluble carboxylic acids to water-soluble alkali metal or ammonium salts and then extract them into aqueous solution.

Scientists Find Origin-of-Life Molecule in Space for First Time

— By Jess Thomson | August 8, 2023

molecule common to Earth and usually associated with life has been detected in the depths of space by scientists.

Carbonic acid (HOCOOH), which you may know as the chemical that makes your soda fizzy, was discovered lurking near the center of our galaxy in a galactic center molecular cloud named G+0.693-0.027, a study published in The Astrophysical Journal revealed.

This marks the third time that carboxylic acids—this class of chemicals, often thought to be some of the building blocks of life—have been detected in space, after acetic acid and formic, and the first time that an interstellar molecule has been found to contain three or more oxygen atoms.

"Our observations have allowed us to know that carbonic acid, which until now had remained invisible to our eyes, is relatively abundant in space, which makes it an essential piece to understand the interstellar chemistry of carbon and oxygen, two of the fundamental chemical elements in any prebiotic process," Víctor M. Rivilla, a researcher at the Spanish Center for Astrobiology and co-author of the study, told German broadcaster Deutsche Welle (DW).

"This result confirms that the path we have chosen is the right one to search for, and detect more molecules that we suspect were key to the appearance of life on our planet," he concluded.

Carboxylic acids are a type of organic compound characterized by a carbon (C) atom doubly bonded to an oxygen (O) atom and singly bonded to a hydroxyl group (―OH). Carbonic acid in particular is formed when CO2 is dissolved in water, meaning that it is present in increased concentrations in our seas due to CO2 in the atmosphere.

Many theories as to how life on Earth evolved suggest that primitive life may have emerged from a primordial soup of chemicals when our planet was very young. Some have suggested that these chemicals, including carboxylic acids, may have arrived on Earth from space, traveling via comets and meteorites to the forming planet.

Carbonic acid has been previously detected on other astronomical bodies, including the icy moons of Jupiter, in some meteorites and comets, and even on Mars and Mercury, but until now, has not been seen in interstellar space.

The authors explained that the discovery of these more complex molecules in the interstellar medium may reveal clues about the origins of our planet and the life upon it.

"The presence of prebiotic COMs within extraterrestrial material thus firmly suggests the existence of carboxylic acids of increasing complexity in the ISM (interstellar medium), including amino acid–related species. Within this context, considerable efforts have been devoted to hunting for other acids, such as propenoic or acrylic acid, propanoic acid, cyanoacetic acid, glycolic acid, hydantoic acid, and glycine, whose identification in the [interstellar medium] remains elusive."

carboxylic acid

3D Amino Acids Augmented Reality Application. Amino acids are organic compounds that contain aminoa and carboxylic acid (−CO2H) functional groups, along with a side chain (R group) specific to each amino acid. The elements present in every amino acid are carbon (C), hydrogen (H), oxygen (O), and nitrogen (N) (CHON). In addition sulfur (S) is present in the side chains of cysteine and methionine, and selenium (Se).

Welp, my faculty's organic chemists have officially lost it and it unfortunately isn't just a joke. I'm only now realizing the amount of material for the upcoming test (test!!!) could easily make up a whole exam. Not sure how I'm supposed to retain it all in like a week (with classes and other uni work in between???) and rn the situation is tragic. Screaming crying etc. How am I not to hate ochem when this course is sheer chaos run by what seems to be three mischievous racoons in disguise? 😭

Hi, this may be the “finals drawing near and studying melting my brain” talking but im losing my mind over the twin rings and it has begun to actually hurt my brain. And félix didnt get blorbo status in my brain until recently so i never really thought too deeply about his actions???

I know there’s people out there who have put huge amounts of thought into the amok lore, because i saw u in the wilds of tumblr a while ago and then proceeded to ignore it because i was too busy with my Other Blorbos, and now idk where to find posts, so, if you’re out there, here are some questions, i am imploring you for your wisdom

—why did gabe use the ring to threaten félix in the episode félix. “You know what i could do with a snap of my fingers,” or whatever. Was he talking about the peacock? The peacock wasn’t even fixed yet. It was still broken. Could he use the peacock to kill félix? I thought you needed the amok to do that???

—WHY did félix give adrien’s ring BACK to gabriel in risk. What the fuck benefit did that give him. He had blackmail and ALL of those miraculous????? He was already winning why was he like “and THIS, i wont be needing it anymore 😏” what the HECK félix.

—“anymore.” Why did he need it to BEGIN with then. Like. Is he protecting adrien with the peacock??? Is that even a thing????? He spent a while in hiding doing nothing why did he not swoop in to protect adrien sooner??? Did he even DO anything to protect adrien when he had the other amok????? Was he just constantly whispering like “adrien u can make your own choices youre free” into the ring and we didnt see it?????

—WHY IS HE SO BAD AT BARGAINING????? This isnt a lore question this is just. Still not over it. Félix what the fuck. Do you know how bargaining works. You dont play all of your cards at once. I get that he’s impulsive but SERIOUSLY my GUY. You are so STUPID why did you OFFER the ring to gabriel you dumb bitch

—amelie being like “you can keep it félix, i just wanted the ring back on our side of the family 🥰” at the end of félix makes me genuinely insane now. WHY. Amelie what did you want it on your side of the family for. Amelie couldve been like “oh we gotta give that to adrien” but instead she was like “yeah my sweet little murder boy will take good care of his cousin who he bullies”

—by the way this is not me complaining and this is not intended to be a space to complain,,, this is a space to go “omg these fictional guys are soooooo stupid and messed up (affectionate)” and try to unpack and come up with an explanation for what could’ve possibly made them act that way. Félix makes me more insane the more i study him . i hate him so much (affectionate)

(Also please please please please do not reference any leaks i am avoiding them okay thank u)

ordered a streetcar for my exam and the guy making it goes, “oof, that kinda test huh?”

[whats-in-a-sentence]

(Recall from chapter 11 that the smaller the pKa the more acidic is the group. At lower pH, carboxylic acids are found in the RCOOH form and amines are found in the RNH3+ form. At higher pH, the opposite is true; carboxylic acids are present as the salt RCOO- and amines are present as uncharged RNH2. Figure 24.3 on p. 1061 shows how this looks at different pH.)

Next, the solution is titrated with 1.00 M NaOH; the volume of base added and the pH of the resulting solution are recorded and then plotted as shown in figure 24.3. (...) By examining the titration curve (figure 24.3), you can see that the isoelectric point for glycine falls halfway between the pKa values for the carboxyl groups and the ammonium ion:

ew i rly don't want to learn those 20 amino acids ://

[tenth-sentence]

Substitution at the α-carbon with an atom or a group of atoms of higher electronegativity than carbon increases the acidity of carboxylic acids, often by several orders of magnitude.
