Reaction equilibria of using glycine buffer when small amounts of HCL are added?
When small amounts of HCl are added to a glycine buffer, the acidic buffering capacity of glycine will neutralize the added HCl by accepting protons, maintaining the pH of the solution relatively constant. The reaction involves the protonation of glycine to form a zwitterion, which helps to minimize changes in pH due to the addition of the acid. Overall, the buffer system resists drastic changes in pH by reacting with both the acid and its conjugate base.
What is procedure for formol titration of determining glycine?
In the formol titration method for determining glycine, formaldehyde is added to a solution of glycine, resulting in the formation of a white precipitate of formyl glycine. The excess formaldehyde is then titrated with a standard solution of sodium hydroxide to determine the amount of glycine present in the original solution. The endpoint is reached when a pink color change is observed due to the formation of a chromophore from the excess formaldehyde.
Why would glycine increase in pH after the addition of hcl?
Glycine is an amino acid with both an amine group and a carboxyl group. When HCl is added, it reacts with the amine group, forming ammonium chloride. This reaction consumes H+ ions, leading to an increase in pH.
What is called when phosphates are added to a molecule?
Phosphorylation is the process where phosphates are added to a molecule, typically through the transfer of a phosphate group from ATP to the target molecule. This process is important for regulating protein activity, signal transduction, and various cellular functions.
When polysaccharides are divided into monosaccharides what molecule must be added?
water must be added and the process is called Hydrolysis

Why did we use glycine for the pH of 10 buffer?
Glycine is used for a pH 10 buffer because it has a pKa value of approximately 9.6, making it effective for buffering near this pH. At pH 10, glycine exists in a form that can help resist changes in pH when acids or bases are added. Its zwitterionic nature allows it to act as both a weak acid and a weak base, providing stability in the desired pH range.
What is the name of an organic molecule when hydrogen is added to it?
Hydrate
What is added to a glucose molecule to make fructose?
both glucose and fructose are monosacharides, so you can add someting to a mono... to make another one. although, if you add them together, you get sucorse
What is a R-group?
an added chain of hydrogen to a molecule which varies to the size of the molecule its a combination of o and h

What part of the molecule gets constantly added and removed?
The functional groups, such as hydroxyl (-OH) or phosphate (-PO4), are the parts of a molecule that often get added or removed during chemical reactions. These functional groups can alter the properties and reactivity of the molecule.
What are the terms of a sequence added together?
The terms of a sequence added together is the sum.
What is called when phosphates are added to a molecule?
Phosphorylation is the process where phosphates are added to a molecule, typically through the transfer of a phosphate group from ATP to the target molecule. This process is important for regulating protein activity, signal transduction, and various cellular functions.
