What are the four levels of protein structure? - Answer-primary, secondary, tertiary, quaternary primary structure - Answer-The first level of protein structure; the specific sequence of amino acids making up a polypeptide chain. secondary structure - Answer-The second level of protein structure; the regular local patterns of coils or folds of a polypeptide chain. tertiary structure - Answer-The third level of protein structure; the overall, three-dimensional shape of a polypeptide due ...

What is the D configuration of a sugar in a Fisher projection? - chyrol carbon furthest from the carboxyl group hydroxyl on right What is the L configuration of a sugar in a Fisher projection? - hydroxyl on left What is the difference between glycogen and amylopectin? - glycogen- has branches about every 10 residues (more highly branched) amylopectin- has branches about every 25 What is amylose made up of? - glucose What makes up starch? - amylose amlyopectin What is a glycosidic bond?...

________________ are polymers of monosaccharide monomers - polysaccharides acids - donates protons, H+ is in higher concentration aldose - carbonyl group at end of carbon chain alpha linkage - starch (more for energy storage) amino groups - attract a proton and act as bases anion - gains electrons, negative charge atomic number - number of protons, orders the elements atomic weight - mass of all the naturally occurring isotopes bases - bases - accept protons beta linkage - cellulose (m...

Cell Biology Macromolecules Questions and Answers Already Passed What are the four main macromolecules? Lipids, Proteins, Carbohydrates, and Nucleic Acids What three of the four main macromolecules are made from monomers? Proteins, Carbohydrates, and Nucleic Acids What is a dehydration reaction? It is when a water molecule is taken away, in order to form a new bond (synthesizing a polymer). What is hydrolysis? It is when a water molecule is added, in order to break a bond (breaking down a pol...

Ultimate Study Guide for Science Bowl— Biology Rated A+ Ether Lipid Lipids in which one or more of the carbon atoms on glycerol in bonded to an alkyl chain via an ether linkage, as opposed to the usual ester linkage. Ethers (plasmalogens) Class of organic compounds that contain an ether group--an oxygen atom connected to two alkyl or aryl groups-- of general formula R--O--R'. Peroxisome (Microbodies) Organelles found in all eukaryotic cells--they are involved in the catabolism ...

[H+][OH−] = 10−14 - pOH- subtract from 14 pH-look at exponent 4 macromolecules - 1. carbohydrates 2. lipids 3. proteins 4. nucleic acids Acidic - more H+ 1-6 Adhesion / cohesion - Cohesion - ability of water to attract to itself Adhesion - ability of water to cell walls of others ** allows transport against gravity in plants Surface tension ALL 3 DOMAINS OF LIFE HAVE - PHOSPHOLIPID BILAYER ALL LIPIDS - DO NOT DISSOLVE WELL IN WATER *think olive oil in a cup of water alpha linkag...
