Organic chemistry is life; everything else is waiting. Explanations of biological homochirality's origin are poor at best (read: pathetic),

Quantitative geometric chirality is rigorously defned by mathematican Michel Petitjean, including its calculation in QCM software,

It's a truly nasty field to study as pure math,

Review of quantitative geometric chirality

As long as you are in homogeneous isotropic solution, an organiker's view is good enough for an organiker(e.g., ORD spectroscopy) even though it has little rigor and is seriously wrong at its edges,

No, biochemistry is life. Organic chemistry, unlike biochemistry, includes a great deal that's not found in living organisms.

organic chemistry is vocabulary to biocemistry... IT IS WHAT WE R!!! ORGANIC

Lexan polycarbonate and a ton of other compounds, including dozens of amino acids, are organic, but they're not (naturally) found in living organisms.

Biochemistry ... IT IS WHAT WE ARE!!!!

[FREYA021]

amono acids not found in organisms???? do u know what u wrote?...
and hello! u need to be the best organicher if u tend to become biochemist, scientific one, more chem less biology with is describleble science, not exact as chemsitry, math or phisics
ps if u dont know other living forms it doesnt mean that they dont exsist

The question is, did you read what he wrote?

[FREYA021]

it is typo and u know it! ty

Telemad: Lexan polycarbonate and a ton of other compounds, including dozens of amino acids, are organic, but they're not (naturally) found in living organisms.

FREYA021: amono acids not found in organisms???? do u know what u wrote?...

Why yes, I do.

The real question is, do you not know that there are dozens of amino acids that are not found in living organisms?

Let’s do some simple math. There are 20 ‘universal’ amino acids (and one or two other less common ones, such as selenocysteine) used during protein synthesis. But the following quote explicitly states that there are many more amino acids than these.

“The Murchison meteorite, which fell near a small town in Australia in 1969, contains at least seventy-four amino acids, including eight or more of the twenty amino acids that make up proteins in organisms on earth.” (Jeffrey L. Bada, Cold Start. (Origins of Life on Earth), The Sciences, May-June 1995 v35 n3 p21(5))

So sticking with the 74 amino acids from the quote, that would leave about 50 amino acids not (naturally) found in living organisms.

yea yea and pigs could fly! oink oink
have u heard of combination? permutation? and r amino acids question of organic or biochemistry?
and by the work of E.Fisher amino acids r the result of destiction of proteins in flora and fauna; they have COOH and amino group so can COMBINE! and on an on so u have polipeptids...
what they may found is maybe strange combination, but it is organic... remember what i said earlier IF U DONT KNOW OTHER LIVING ( read organic) FORMS IT DOESNT MEAN THEY DONT EXSIST

So you are so stubborn as to reject straightforward logic and science. I was right, you were wrong. Live with it.

FREYA021: and r amino acids question of organic or biochemistry?

Those found in living organisms are in the realm of biochemistry and organic chemistry; those not found in living organisms are in the realm of organic chemistry only.

As before, biochemistry can be though of as the subset of organic chemsitry that deals with life. The chemistry of life is found in that subset, whereas much chemistry not of life is found outside the biochemistry subset of organic chemistry. Get it yet? Are you familiar with subsets?

FREYA021: and by the work of E.Fisher amino acids r the result of destiction of proteins in flora and fauna;

If that's what he actually said, then he's wrong: or more accurately, his statements would be incomplete.

Amino acids are also formed abiotically: we've found them in meteorites, for example, and Stanley Miller produced them by passing electric discharges through a strongly-reduced gas 'atmosphere' (that supposedly modeled the prebiotic Earth's).

So no, amino acids are not only found in the proteins of flora and fauna. Stating that they are is a false statement.

FREYA021: what they may found is maybe strange combination, but it is organic... remember what i said earlier IF U DONT KNOW OTHER LIVING ( read organic) FORMS IT DOESNT MEAN THEY DONT EXSIST

A better statement is, JUST BECAUSE YOUR IMAGINATION CAN RUN WILD AND YOU CAN FABRICATE SOME HYPOTHETICAL LIFE FORM UNLIKE ANYTHING WE KNOW OF DOESN'T MEAN IT DOES EXIST.
