Building blocks of proteins are the beta-amino acids

Click For Summary
SUMMARY

The discussion centers on the structural components of proteins, specifically addressing the validity of various statements regarding amino acids and protein structures. Statements (e), (f), and (h) are confirmed as true, indicating that -COHN- represents a peptide linkage, the order of amino acids defines the primary structure, and the overall shape of a protein is its tertiary structure. Statements (b) and (c) are considered likely true, while the accuracy of statement (d) regarding polar amino acid side chains is questioned. The molecular weight range of proteins in statement (a) is also noted as potentially incorrect.

PREREQUISITES
  • Understanding of protein structure, including primary, secondary, and tertiary structures
  • Knowledge of amino acid properties and classifications
  • Familiarity with peptide linkages and their significance in protein formation
  • Basic biochemistry concepts related to molecular weight and protein composition
NEXT STEPS
  • Research the properties of beta-amino acids and their role in protein synthesis
  • Study the differences between fibrous and globular proteins
  • Explore the significance of secondary structures, such as alpha helices and beta sheets
  • Learn about the implications of amino acid sequence on protein functionality
USEFUL FOR

Biochemists, molecular biologists, and students studying protein structure and function will benefit from this discussion, particularly those interested in the properties and classifications of amino acids.

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 I am not sure. which ones are true?

The statement that is wrong is based on a (bio)chemical property.

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