You can use the formula M1 x V1 = M2 x V2 where M1 is the molarity of the first substance and V1 is the volume of the substance. M2 is the molarity of the 2nd substance and V2 is the volume of the substance
if substance 1 is HCl and 2 is KOH we can set up the following equation
x moles / liter (unknown) x .02 liters = .5 moles/ liter x .032 liters
x moles / liter x .02 liters = .016 moles
x moles / liter = .016/.02 liters
x moles / liter = .8 moles/ liter
You have . 8M HCL
Answer:
The right answer is A)The primary structure of a protein is the order of amino acids in a polypeptide, as coded for in the DNA of a gene.
Explanation:
Proteins are aminoacids´s polymers. There are 20 different aminoacids that differs only in their R groups. There are four kind of protein structures:
1) Primary structure: it refers to tha secuence of aminoacids in the protein and is defined by DNA.
2) Secondary structure: it describes the situation in which we can identify repeated segments along the polypeptid chain. There are two secondary structures: alpha helix and beta pleated. This two conformation are held together by interactions between peptidic groups. R groups can interact only if they are small.
3) Tertiary structure: is the three-dimentional conformation of the polypeptid and it is stabilized by hydrogen bonds, electrostatic interactions, hydrophobic interactions and disulphide bonds. Stabilizing bonds can be between peptidic groups (peptide bond).
4)Quaternary structure: it applies for that proteins conformed by different subunits. It describes the conformation and interaction between these subunits in the polypeptid.
