What are peptide bonds?
Peptide bonds are covalent bonds that link amino acids together in a protein chain. They are formed through a condensation reaction between the carboxyl group of one amino acid and the amino group of another amino acid, resulting in the release of a water molecule. Peptide bonds are crucial for maintaining the structure and function of proteins, as they determine the sequence of amino acids in a protein chain. **
What is correct: peptide bond?
A peptide bond is a covalent bond that forms between the carboxyl group of one amino acid and the amino group of another amino acid during protein synthesis. This bond is formed through a condensation reaction, where a molecule of water is removed. The resulting bond is a strong and stable linkage that holds the amino acids together in a protein chain. Therefore, the correct term is "peptide bond" to describe this specific type of covalent bond between amino acids. **

Marengo Mario Barolo 'Brunate' Mario Marengo 2021Barolo "Brunate" by Mario Marengo offers a unique interpretation of this renowned cru of the denomination. In a reality like this, where tradition has been the glue for generations and respect for the grapes and the wine itself is a religious commandment, the Barolo produced in Brunate acquires added value. The vineyards stretch between Barolo and La Morra, on a single amphitheater slope that presents ridges of significant elevation and enjoy a historically favorable microclimate: the large temperature swings between night and day ensure that the grapes take on unique and singular characteristics, which inevitably impact those of the wine itself. The Barolo "Brunate" by Mario Marengo comes from Nebbiolo grapes of the cru Brunate, at an altitude between 400 and 230 meters above sea level. The vines, exposed to the south, are over 80 years old and are located on a soil mainly composed of mixed clays and very fine calcareous sands. A characteristic of the soil is the presence of Sant'Agata marls and fossils from the Tortonian period. No wonder Brunate is one of the most important and renowned crus of Barolo, where we find calcium and manganese carbonates that enrich and nourish the plants. The vinification takes place in steel tanks, where malolactic fermentation is also carried out, at controlled temperature. The aging lasts 24 months in oak barrels. “Brunate” Barolo by Mario Marengo presents a not too intense ruby red color with intriguing garnet reflections. Once poured into the glass, aromas both characteristic of Nebbiolo such as cherry, rose, and violet, as well as fruity notes of jam made from dark fruits and currants, reach the nose. Balsamic notes emerge in the finish, with hints of mint and eucalyptus foremost. On the palate, it reveals a rigorous and clear Barolo, concrete and very elegant. The tannin, thanks to the grapes that undergo temperature swings in the vineyard, is soft and succulent, less abrasive than other crus. The freshness integrates well and persists excellently, along with the other aromas that stretch and unfold in the sip.57,00 £*Shipping: 48,00 £Secure redirect to the provider

What is a peptide bond, peptide chain, peptide group, di-, tri-, and polypeptide? Can you please explain this briefly and simply? Thank you.
A peptide bond is a chemical bond that forms between the carboxyl group of one amino acid and the amino group of another amino acid. When multiple amino acids are linked together by peptide bonds, they form a peptide chain. A peptide group refers to a group of amino acids linked together by peptide bonds. A dipeptide is a chain of two amino acids, a tripeptide has three amino acids, and a polypeptide is a chain of many amino acids linked together. These chains of amino acids are the building blocks of proteins. **
-
What is the stability of peptide bonds?
Peptide bonds are relatively stable under normal physiological conditions. They are formed through a condensation reaction between the carboxyl group of one amino acid and the amino group of another, resulting in the release of a water molecule. This covalent bond is strong and resistant to hydrolysis, making it stable in the presence of water. However, under extreme conditions such as high temperature or strong acids or bases, peptide bonds can be hydrolyzed, leading to the breakdown of the peptide chain. **
-
How does hydrolysis occur during peptide cleavage?
Hydrolysis occurs during peptide cleavage when a water molecule is used to break the bond between the carboxyl group of one amino acid and the amino group of another. This process involves the addition of a water molecule to the peptide bond, resulting in the separation of the two amino acids. The water molecule donates a hydrogen ion to one amino acid and a hydroxide ion to the other, causing the bond to break and the peptide to be cleaved. This hydrolysis reaction is catalyzed by enzymes called proteases, which facilitate the cleavage of peptides in biological systems. **
-
Why are peptide bonds not freely rotatable?
Peptide bonds are not freely rotatable because of the partial double bond character that arises from resonance in the peptide bond. This restricts the rotation around the bond and locks the peptide backbone into a planar structure. The resonance forms a rigid, flat structure that allows for the formation of the alpha helix and beta sheet secondary structures in proteins. This rigidity is essential for maintaining the specific three-dimensional shape and function of proteins. **
How does one go from DNA to peptide?
The process of going from DNA to peptide involves several steps. First, the DNA sequence is transcribed into messenger RNA (mRNA) by the enzyme RNA polymerase. The mRNA is then translated by ribosomes, which read the mRNA sequence in groups of three nucleotides called codons. Each codon corresponds to a specific amino acid, which is the building block of a peptide. As the ribosome reads the mRNA, it links together the corresponding amino acids to form a peptide chain. This chain of amino acids folds into a specific three-dimensional structure to form a functional peptide. **
How can one recognize mesomerically stabilized peptide bonds?
Mesomerically stabilized peptide bonds can be recognized by the presence of resonance structures in the peptide bond. This is typically observed when the peptide bond is part of a conjugated system, such as in the case of proline or in the presence of aromatic amino acids like phenylalanine or tyrosine. The presence of resonance structures indicates that the electrons in the peptide bond are delocalized, leading to increased stability. Additionally, mesomerically stabilized peptide bonds may exhibit altered reactivity compared to non-stabilized peptide bonds, making them important in the study of protein structure and function. **

Il “Valmaggiore” è un Nebbiolo d'Alba prodotto da una cantina che ha la sede nel cuore delle Langhe, nella zona di La Morra, da sempre famosa per i grandi Barolo. Proprio la profonda conoscenza del vitigno Nebbiolo e l’esperienza nella sua vinificazione, hanno condotto Mario Marengo in Roero, sull’altra riva del fiume Tanaro, alla ricerca di territori d’eccellenza. Le uve di Nebbiolo provengono dalle vigne coltivate nella zona della Menzione Geografica Aggiuntiva Valmaggiore, nel territorio comunale di Vezza d’Alba, uno dei cru più quotati dell’area del Roero. Al termine della vendemmia manuale, si procede alla classica vinificazione in rosso in serbatoi d’acciaio inox a temperatura controllata, con macerazione sulle bucce. Il vino matura per circa un anno in barrique di rovere francese e completa l’affinamento con alcuni mesi in bottiglia prima della messa in commercio. Il “Valmaggiore” Mario Marengo è una bella versione del classico rosso piemontese, particolarmente adatta per chi ama la finezza espressiva. Alla vista si presenta di colore rosso rubino con lievi riflessi granato. All’olfatto è elegante ed esprime profumi delicati di piccoli frutti a bacca rossa, lampone, ribes, ciliegia, sfumature di erbe officinali, di petali di fiori secchi, cenni delicati di vaniglia, radice di liquirizia e morbide spezie orientali. Al palato è di media struttura, con una tessitura tannica finissima, ben integrata al frutto e accompagnata da pregevoli sfaccettature d’aromi terziari. Il finale e di buona persistenza, fresco e sapido.21,00 £*Shipping: 48,00 £Secure redirect to the provider

Mario Schiopetto 2023The Mario Schiopetto is a Friulian white wine that comes from an intuition of Mario, the founder of the winery in 1965, in uniting indigenous and international grape varieties to create labels with a unique flavor. And it cannot be said that, after several years, this vision has not been successful, considering that the Mario Schiopetto is a product that, vintage after vintage, continues to confirm itself at the top of the main national industry guides. A bottle of excellent quality, which offers a nice ease of drinking without hiding its strong and never submissive character, marked by a pronounced minerality. The Mario Schiopetto is a white wine that the Schiopetto winery produces from an indigenous grape variety, the Friulano, and a small part of Riesling grapes. Both contribute to the creation of the final blend and are cultivated according to criteria and practices aimed at minimizing the production's impact on the environment. The bunches, carefully selected during manual harvesting, after vinification move on to the aging phase, which is carried out first in steel for 30 months, and then for 9 months in tonneau. The Mario Schiopetto is a wine that in the glass presents itself with a straw yellow color, crossed by reflections that recall the color of emerald. Exotic fruit and citrus are the notes that are first perceived on the nose, and that, little by little, give way to briny and floral touches. On the palate, the sip is organized on a significant mineral structure, which helps to give the sip personality, also thanks to a remarkable persistence of the finish. A bottle that deserves more than one tasting and confirms the great potential of the Friulian terroir in the production of white wines.66,00 £*Shipping: 48,00 £Secure redirect to the provider
