Which of the following are true ?



(a) Proteins range from a MW from about 3,000 to 1.0e6 g/mol

(b) Fibrous proteins are the main component of Muscle,hair and cartilage

(c) Building blocks of proteins are the beta-amino acids

(d) Polar amino acid side chains are hydrophobic

(e) -COHN- is a peptide linkage

(f) The order of amino acids in a protein chain is the primary structure

(g) The beta sheet is a secondary structure of a protein

(h) The overall shape of a protein, eg globular, is its tertiary structure

I know for sure that e f h are true and most likely c and b but im not sure. which ones are true?

If you look at this page you should see a pattern between amino acid and their propertities.
