Determine whether the structure, location, and functions describe proteoglycans, peptidoglycan, glycoproteins, or glycolipids. GlcNAc is N-acetylglucosamine; MurNAc is N-acetylmuramic acid. Proteoglycans Peptidoglycan Glycoproteins Glycolipids Structure Location part of proteins at outer surface of plasma membrane, in extracellular matrix, and in blood Functions many functions, including cell adhesion strength for cell envelope Answer Bank glycosaminoglycan covalently joined to a protein at a Ser residue many functions, including acting as hormones bacterial cell wall extracellular matrix; some are integral membrane proteins outer...
1 - Draw the chemical structure of ATP. Describe what is the same, and what is different from the 'A' in an RNA strand. Besides being used to make RNA, what other biological importance does ATP have? 2 - What is the central paradigm of Molecular Biology? What are the molecular machineries that facilitate each step? 3 - Draw the chemical structure of the amino acids glycine, alanine, valine, leucine, and isoleucine. Give a reason why an organism would need...
What features come together to create the specific chemical environment within the active site of an enzyme? the unique combination of amino acid residues, their positions, sequences, structures, and properties the unique combination of amino acid residues, the size of the polypeptide chain, and other physical properties the unique combination of charged and polar amino acid residues the unique combination of amino acid structures, their variable sequences and properties
What is the difference in structure between a polyunsaturated fat and a trans fat? Please draw a diagram.
1. a. For the following groups, indicate their predominant ionic species (draw the chemical structure) at pH 7.4: a. The side chain amino group (–NH3+) of the amino acid lysine, pKa=10.5. The side chain carboxyl group (-COOH) of the amino acid glutamate, pKa=4.1. b.For a buffer with a pKa of 8.03 : How will the pH and buffering capacity change when HCl is added to the buffer in “a”? How will the pH and buffering capacity change when NaOH is...
(Molecular Biology) Draw a diagram of the cloverleaf structure for the tRNA of Aspartic Acid and point out the specific sequence of the site to which the amino acid attaches and the site of the anticodon.
What is the difference between a tRNA entering the A site of the ribosome and a tRNA leaving the exit site of the ribosome?
4 - What is the difference in the chemical structure of starch and cellulose? What is the structural effect of this difference, and its biological role?
what is the difference between site of action and mechanism of action ?
S-adenosylmethionine (SAM, top structure) reacts with norepinephrine (bottom structure) to form epinephrine. Draw curved arrows to show how this reaction proceeds. The first curved arrow is drawn for you–a basic amino acid side chain (B) is positioned in the active site to deprotonate the amine. S-adenosylmethionine (SAM, top structure) reacts with norepinephrine (bottom structure) to form epinephrine. Draw curved arrows to show how this reaction proceeds. The first curved arrow is drawn for you- a basic amino acid side chain...
