Amino acids are called "amino acids" because they contain an amino group (NH2) and a carboxyl group (COOH) that is acidic. In the figure above, you can see the chemical structure of two of the amino acids. You can see that the top part of each one is the same. That is true of ...
(1994) Acidic carboxyl-terminal domain of gene 2.5 protein of bacteriophage T7 is essential for protein-protein interactions. J. Biol. Chem. 269, 5270-5278Kim,Y.T.,Richardson,C.C.Acidic carboxyl-terminal domain of gene 2.5 protein of bacteriophage T7 is essential for protein-protein ...
An ester can be broken into carboxylic acid and alcohol by a process called"Hydrolysis". The reaction can be carried out in either acidic or basic conditions. The reaction of ester with water is very slow and is generally catalyzed by dilute acids, such as hydrochloric acid and sulfuric acid...
But, heavy metals are potent inhibitors of photosynthesis as they can replace or block the prosthetic metal atoms in the active sites of certain enzymes. Likewise, the acidic functional groups of bacterial cell walls can also bind significant concentrations of aqueous cations, which can affect th...
Osteopontin (OPN) is an acidic secreted glycosylated phosphoprotein which originates from bone marrow hematopoietic stem cells and widely present in bone, kidney, immune system and blood system. In the skeletal system, it is secreted by osteoblasts and osteoclasts [21]. OPN is a vital regulator ...
Question: Identify the amino acid that is a catabolic precursor of theα-keto acid below. Alpha-keto Acid: Eliminating the amino group from the amino acids gives alpha-keto acids. As alpha-keto acids are ketogenic or glucogenic precursors, the carbon skeletons of these amino a...
Suppose you have discovered an acidic amino acid. Its carboxyl group p K a is 1.9. Its amino group p K a is 9.5. Its side chain p K a is 2.9. At pH 11.2, what will net charge be? a) +1 b) +2 c) 0 d)-1 When alanine (N-terminal) and glycine (C-terminal) are linked ...
In agreement with this model, a randomly generated peptide binding assay identified aspartic acid (acidic residue) as the preferential − 1 residue interacting with Scrib PDZ-1 and − 3 (Fig. 2A), which harbor a basic residue at position β3C5 in close proximity to the interacting PDZ-...
Why are carboxyl groups considered acidic? Explain why the pH of 1.0M hydrochloric acid is 1.0M while that of 1.0M ethanoic acid is 5.0. Explain why the pH decreases when SO_3 is dissolved in water. An acid, HA, is 90% unionized. Is this a strong or weak acid? Explain. ...
the term “carboxyl group” refers to a group of formula —COOH; the term “carboxyl ester group” refers to a group of formula —COOR, wherein R is a radical actually or notionally derived from the hydroxyl compound ROH; and the term “carboxamide group” refers to a group of formula ...
