Proteins

amino acid structure

has the functional group hydroxyl ,carboxyl and amino

dipeptide structural formula is held by ?

the peptide bond is c and N

what’s a polypeptide

an amino acid forming a chain

what’s a conformation of a polypeptide

each protein has a complex 3 dimension shape

what’s a primary structure

a line of amino acids(polypeptide) held together by covalent bond amino bond at the end and carboxyl on the other end

what’s a secondary structure

the local repeating spatial folding of the protein bone, an allpa helix and beta helix

what’s a tertiary structure

a 3 dimensional shape interacts between R groups

what’s a quaternary structure of a polypeptide

3 dimensional shape with 2 or more polypetide

what type of bonds hold the primary structure together

peptide bonds and covalent bonds

what type of bonds and IMFs hold the 2ndary structure

hydrogen bonds between amino and carboxyl

name all of the bonds and IMFs that hold a tertiary structure in place

r groups connect to hydrogen bond (oh)

what bonds and IMF hold amino acids to form proteins

strong covalent bonds and hydrogen bonds

what will happen to a protein’s shape if you change 1 amino acid in the primary structure

it alters the sequence and changes the proteins shape and function this process is denaturalization

what denaturation how can it happen?

its when a protein or nucleic acid looses its natural 3 dimensional structure. it can happen if theres a disruption of a weak chemical bond.(ex hydrogen bond)

what does DNA tell RNA

DNA tells RNA to tell the proteins what to do and how to arrange themselves

what structure do all proteins have

primary structure, secondary structure, and tertiary structure

what does each amino acid have

hydrogen atom, carboxyl group and variable r group

how many amino acids in the body

there are 20 and each have their own unique R groups

what do r groups do to the conformation ((3 dimensional shape ) of a protein

R groups of a protein come in various types and thus varies the conformation of a protein

examples of r groups being different

some r groups are polar (they have either HO or NH2 ) or non polar, and they can be negtaviley charged

what does a proteins function depend on

proteins functions depend on their conformation

why don’t all proteins have a quaternary structure

because they need 2 or more polypeptides to form

Hydrolysis and peptides

hydrolysis breaks polypeptide bonds to separate them into peptides
