Discussion of Biochemistry - Carbohydrates part I - NEET pattern

1. Inulin

Inulin is a homopolymer of fructose and contains least amount of glucose at the terminals.

As inulin is neither absorbed nor secreted in kidney, use for GFR estimation

Human enzymes can attack only alpha glycosidic linkage. As inulin and cellulose contain beta glycosidic linkage they are not digested. Cellulose is fermented by the help of intestinal bacteria. Pectin is neither digested nor fermented. 

2. Insulin Inhibits Glycogen Phosphorylase

Glycogen phosphorylase increases blood sugar. So insulin will inhibit it. This is easy. 

I want you to memorize this simple fact --> Whichever enzyme increases the blood glucose will be active in phosphorylated form.

3. Epimers

Epimers differ around a single carbon. Galactose is C4 epimer of glucose. Mannose is C2 epimer of glucose. Galactose and mannose are NOT epimers as they differ in more than one carbon

I guess you know everything about rest of the questions. If you really want, inform me.
