What are the structure levels of proteins?
1st level, 2nd level, Tertiary, and Quaternary. The first level is just the different protein groups forming peptide bonds to create a polypeptide The second level consists of hydrogen bonds between the H and the O molecules in the proteins forming pleated and helical shapes The Tertiary structure is the interactions of different R groups binding to each other (many different types of bonds happen between the R groups) The Quaternary structure is many polypeptides interacting with each other
Where can macromolecules be found?
Two molecules in living things that form hydrogen bonds are DNA and protein. Hydrogen bonds form between the two strands of DNA and form when a protein is being folded into its final conformation.
What bond forms between units of a macromolecule?
Organic macromolecules have covalent bonds.
What term best describes a cell membrane?
A double layered fluid structure containing sort of loose but contained things such as proteins, cholesterol molecules, etc. It has a hydrophobic layer of longer apolar lipid chains sandwiched in between two hydrophilic (polar) lipid edges.
What is the comparison between the structure of starch and protein?
* Both are macromolecules (large molecules). * Both are polymers, having similar repeating units. * Starch is a polysaccharide, and specifically a polymer of glucose; proteins are polymers of amino acids. There are more than 20 different amino acids found in proteins. * Starch consists of both branched and unbranched forms; the polypeptide chains of proteins are not branched (although there may be covalent and other bonds formed different points along chains). * Starch is essentially in the form of long fibrous molecules; proteins have complex secondary (coils, pleated sheets, loops, turns), tertiary (folding) and even quaternary (assembly of two or more chains in some proteins) structures that result in an enormous variety of three-dimensional shapes.
What type of organic macromolecules is formed by polymerization reactions between amino?
Amino acids are monomers of proteins. So they build up proteins
What is binding buffer?
It contain acetate and chaotrope. It disrupts the intermolecular forces between water molecules,allowing proteins and other macromolecules to dissolve more easily.
Do all proteins have quandary structure?
No. Proteins start out as a Primary structure, which is just the linear form and sequence of amino acids. The proteins then start forming alpha helices and/or Beta sheets depending on the properties of the amino acids. This is their Secondary structure The proteins then fold completely into tertiary structure. Here, we have a lot of hydrogen bonding and hydrophobic interactions within the protein between the helices and beta sheets. Many proteins are fully functional in their tertiary structure and don't have any reason for forming into a quaternary structure. In the quaternary structure, we usually see an interaction between 2 or more polypeptides or proteins. An example would be 2 proteins in their tertiary structure binding together to become a functional dimer. If 3 proteins were interacting it would form a trimer. Several proteins are functional only in a quaternary structure while several more proteins are just fine in their tertiary structure and therefore do not have a quaternary structure.
Components of protein?
Proteins are long chains of amino acids. The sequence of amino acids that make up a specific protein is its primary structure. Many proteins have secondary structure that is caused by interactions between associated amino acids, causing kinks or twists in the protein change. Some have tertiary structure, which is caused by joining together of one or more chains.
What determines the degree of relatedness between two different species?
The degree of relatedness between two different species can be determined by taxons and a classificaton system. The classification system is used to organize things into different categories based on their evolutionary relationships.
How are differences between DNA amino acid sequence used to show relatedness between species?
the acid burns the fats
What determines the relatedness between two different species?
whatever the dicoythamus key says is the difference
Where can hydrogen bond be found in living organisms?
in dna i.e between the bases of the polynucleotides in primary, secondary and tertiary structure of proteins
What is the difference between the word protein proteome and proteomics?
You are looking at the study of proteins from different levels and details. Proteins are large biological molecules containing one or more long chains of amino acid.All of the proteins in a virus can be called a viral proteome. All of the proteins in a tissue are called tissue proteomes.Proteomics studies the structure and function of proteins.

What do ribosmoes in the eukaryotic cell do?
Same thing they do in all cells they are in; synthesize proteins. The just differ in subunit structure between prokaryotic and eukaryotic cells.
