Biochemistry worksheet?
Key terms:
Protein, alpha-helix, enzyme, amphoteric molecule, beta-chain, dipeptide, peptide bond, denaturation, intermolecular forces, fat-soluable vitamins, water soluble vitamins
fill each blank with a key term:
1.a biological catalyst is a(n) __
2.Vitamins that are stored in fatty tissues of the body are classified as__
3.When two amino acids are joined, the resulting molecule is a(n) __
4.___ are not stored in fatty tissue of the body and must be included in your daily diet
5.the amide bond between amino acids is called a(n) ___
6.a polymer made of hundreds of amino acid monomers is called a(n)___
7.__is the unfolding of a protein so that it is no longer in its original shape
8.A(n)_____can act as an acid or a base.
9.Weak attractive forces between different molecules or groups in the same molecule are called____
10.The secondary structure of a protein is usually in the form of either a tightly twisted chain called an alpha-helix or pleated sheet called a(n)____
Have you tried googling these terms? It should answer your questions very quickly, however I am feeling generous...
1. enzyme - they catlyze reactions by lowering the activation energy
2. hmm...stored in fatty tissues, must be fat soluble vitamins eh?
3. di is a prefix for 2. so dipeptide
4. the vitamins not stored in fats are not soluble in fat. therefore they are water soluble vitamins.
5. peptide = chain of amino acids. so joining amino acids together is a peptide bond.
6. protein.
7. denaturation
8. amphoteric - ampho means both, and if you look up this word you'll find the definition
9. only one of these terms has forces in it, intermolecular forces.
10. this is a beta-chain.
