Q: What are the largest known proteins?


Read this paragraph and choose the correct option from the provided answers:

Proteins can differ from one another in the number and sequence (order) of amino acids. It is because of the side chains of the amino acids that proteins with different amino acid sequences have different shapes and different chemical properties. Small proteins can contain just a few hundred amino acids. Yeast proteins average 466 amino acids. The largest known proteins are the titins, found in muscle, which are composed from over 27,000 amino acids.

 Choices:

- actins

- hormones

- keratins

- titins


A:
titins
