Detailed explanation-1: -Pectinases (EC 3.2. 1.15) are enzymes that can break down a family of long and complex molecules termed pectins, which occur as structural polysaccharides in several plant tissues, into simpler molecules (e.g., galacturonic acid). There are three types of pectinases: pectin methyl esterase (EC 3.1.

Detailed explanation-2: -Thus, somatotropin is not an enzyme.

Detailed explanation-3: -The pectinase enzyme is broadly classified into three types on the basis of their mode of action: pectin esterase, hydrolases and lyases.

Detailed explanation-4: -Pectic enzyme is a protein that works specifically to break down pectin. It is recommended you use this in almost all fruit wines you make, even commercial wine producers will add pectic enzyme as it aids juice extraction.
