|
globular proteins

Explanation:
Detailed explanation-1: -Primary structure. The simplest level of protein structure, primary structure, is simply the sequence of amino acids in a polypeptide chain.
Detailed explanation-2: -Compounds such as amino acids that can act as either an acid or a base are called amphoteric. The basic amino group typically has a pKa between 9 and 10, while the acidic -carboxyl group has a pKa that is usually close to 2 (a very low value for carboxyls).
Detailed explanation-3: -Fibrous proteins consist of many superfamilies including keratin, collagen, elastin, and fibrin. Collagen is the most abundant of these proteins which exists in vertebrate connective tissue including tendon, cartilage, and bone.
