Right-the classic idea is that somehow nucleotides got together to form a self-replicating molecule (odds are that it was RNA at first, not DNA), and then these self-replicating molecules began to assemble amino acid chains, which, through uncounted bazillions of reacions (keep in mind whole oceans full of molecules, and billions of years) these amino acid/peptides began to have specific  functions.  The newest theory is that proteins formed (which is fairly easy with the right conditions), and some of these were captured in small mycells (little balls of lipids, which form naturally).  In some of them, the proteins interacted with each other to produce energy-generating reactions, and perhaps served as templates for formation of more of the same protein.  We now know this is as least theoretically possible, because of prion diseases, in which small proteins get into cells and cause generation of the same protein chain, independently of the DNA coding mechanism.  So, under this theory, you have mycells full of enzymes, energy-generating ( as in glycolysis or the TCA cycle) and only later did RNA or DNA come to play a role, as a more convenient and stable way to code for the proteins.  This makes a lot of sense biochemically, and is easier to visualize chemcically than the classic theory.  And, it makes sort of an elegant and chemically poetic argument that the origin of life was the thing that really makes life today-the proteins and the protein reaction-and relegates DNA to just a convenient way for the proteins to replicate.

Well, I'm not gonna try to explain this or anything, but check this website out:\n\nhttp://www.usm.maine.edu/~newton/Chy251_253/Lectures/Esterification/Esterification.html\n\nScroll down to "Scheme 2: Saponification of an Ester," and that explains the reaction process fairly well.  I don't know if this is what you're looking for, but I hope it helps!

Amino acids are the basic structural building units of proteins. They form short polymer chains called peptides or polypeptides which in turn form structures called proteins. The process of such formation from an mRNA template is known as translation, which is part of protein synthesis.\nPhenylalanine is one of the standard amino acids.\nEnlarge\nPhenylalanine is one of the standard amino acids.\n\nTwenty amino acids are encoded by the standard genetic code and are called proteinogenic or standard amino acids. Combinations of these amino acids produce every single essential protein for the homeostasis of the human body. At least two others are also coded by DNA in a non-standard manner as follows:\n\n    * Selenocysteine is incorporated into some proteins at a UGA codon, which is normally a stop codon.\n    * Pyrrolysine is used by some methanogens in enzymes that they use to produce methane. It is coded for similarly to selenocysteine but with the codon UAG instead.\n\nOther amino acids contained in proteins are usually formed by post-translational modification, which is modification after translation in protein synthesis. These modifications are often essential for the function of the protein.\n\nProline is the only proteinogenic amino acid whose side group cyclizes onto the backbone: it links to the α-amino group, and thus is also the only proteinogenic amino acid containing a secondary amine at this position. Proline has sometimes been termed an imino acid, but this is not correct by current nomenclature rules.\n\nOver one hundred amino acids have been found in nature. Some of these have been detected in meteorites, especially in a type known as carbonaceous chondrites. Microorganisms and plants can produce uncommon amino acids, which can be found in peptidic antibiotics (e.g., nisin or alamethicin). Lanthionine is a sulfide-bridged alanine dimer which is found together with unsaturated amino acids in lantibiotics (antibiotic peptides of microbial origin). 1-Aminocyclopropane-1-carboxylic acid (ACC) is a small disubstituted cyclic amino acid and a key intermediate in the production of the plant hormone ethylene.\n\nIn addition to protein synthesis, amino acids have other biologically-important roles. Glycine and glutamate are neurotransmitters as well as standard amino acids in proteins. Many amino acids are used to synthesize other molecules, for example:\n\n    * tryptophan is a precursor of the neurotransmitter serotonin\n    * glycine is one of the reactants in the synthesis of porphyrins such as heme.\n\nNumerous non-standard amino acids are also biologically-important: Gamma-aminobutyric acid is another neurotransmitter, carnitine is used in lipid transport within a cell, ornithine, citrulline, homocysteine, hydroxyproline, hydroxylysine, and sarcosine.\n\nSome of the 20 standard amino acids are called essential amino acids because they cannot be synthesized by the body from other compounds through chemical reactions, but instead must be taken in with food. In humans, the essential amino acids are lysine, leucine, isoleucine, methionine, phenylalanine, threonine, tryptophan, valine. Histidine and arginine are generally considered essential only in children, because of their inability to synthesise them given their undeveloped metabolisms.\n\nThe phrase "branched-chain amino acids" is sometimes used to refer to the aliphatic amino acids: leucine, isoleucine and valine.

Photosynthesis (photo=light, synthesis=putting together), generally, is the synthesis of sugar from light, carbon dioxide and water, with oxygen as a waste product. It is arguably the most important biochemical pathway known; nearly all life depends on it. It is an extremely complex process, comprised of many coordinated biochemical reactions. It occurs in higher plants, algae, some bacteria, and some protists, organisms collectively referred to as photoautotrophs.

Show me how Psalms 22 was possible, and how life could have accidentally happened. If you know anything about creation science you must know about chirality of proteins and DNA...   Jim

Biochemistry is the study of the chemistry of life, a bridge between biology and chemistry that studies how complex chemical reactions give rise to life. It is a hybrid branch of chemistry which specialises in the chemical processes in living organisms. This article only discusses terrestrial biochemistry (carbon- and water-based), as all the life forms we know are on Earth. Since life forms alive today are believed to have descended from the same common ancestor, they naturally have similar biochemistries, even for matters which would appear to be essentially arbitrary, such as the genetic code or handedness of various biomolecules. It is unknown whether alternate biochemistries are possible or practical.\n\nBiochemistry is the study of the structure and function of cellular components, such as proteins, carbohydrates, lipids, nucleic acids, and other biomolecules. Chemical biology aims to answer many questions arising from biochemistry by using tools developed within synthetic chemistry.\n\nAlthough there is a vast number of different biomolecules, they tend to be composed of the same repeating subunits (called monomers), in different orders. Each class of biomolecules has a different set of subunits. Recently, biochemistry has focused more specifically on the chemistry of enzyme-catalyzed reactions, and on the properties of proteins.\n\nThe biochemistry of cell metabolism and the endocrine system has been extensively described. Other areas of biochemistry include the genetic code (DNA, RNA), protein synthesis, cell membrane transport, and signal transduction.

Try this , it really helped me in my first few lectures in cell bio , such as DNA and RNA . Loads of animations and stuff ! \n\nhttp://www.johnkyrk.com/DNAtranscription.html

A synthesis reaction is when you start off with 2 substances and end up with 1:\nA+B--->AB\n\nFor example \n\nanhydrous copper (II) sulfate + water --> copper sulfate pentahydrate\nCuSO4 + 5H2O  ---> CuSO4* 5H2O\n\nIn this reaction, the color changes from white to blue. So the color change is the evidence.
