Indicate whether glycine `NH_(2)-CH_(2)-COOH` is an acid or a base.

The peptide linkage formed between glycine (NH_(2)CH_(2)COOH) and alanine underset(CH_(3))underset(|)(NH_(2)CH)-COOH to give glycylalanine can be shown as

Glycine [NH_(2)CH_(2)COOH) is basic and acidic due to presence of -NH_(2) and -COOH group. It acquires a H^(o+) to form overset(o+)NH_(3)COOH , which is a diprotic acid with K_(1) = 4.5 5 xx10^(-3) and K_(2) = 1.7 xx 10^(-10) . In a 0.01M solution of neutral glycine, a. What is the pH and b. What percent of the glycine is in the cationic form at equilibrium?

Glycine (H_(2)N-CH_(2)-COOH) is one of the proteinogenic amino acid. Find moles of glycine in it's 7.5 gm

Glycine exists as the zwitter ion, N^(+)H_(3), CH_(2),COO^(-) . Its conjugate base is

The amino acid in which R group CH_2CH_2COOH is (a) aspartic acid (b) glutamic acid (c) valine (d) threonine

CH_(3)CH_(2)NH_(2) is soluble in :-

Assertion (A): The amino acid glycine predominatly exists in the form of ^(o+)NH_(3)CH_(2)COO^(Theta) . Reason (R) : The conjugate acid of glycine is NH_(2)CH_(2)COO^(Theta) .

The equilibrium constants for amino acids are given in terms of succesive ionization constants of the protonated form.For example, equilibrium constats for Glycine (NH_2CH_2COOH) are K_(a1)=5xx10^(-3) M and K_(a2)=2xx10^(-10)M .What will be the pH at the Isoelectric point for this amino acid and pH of 0.02 M protonated Glycine in pure water respectively ?[Take :log 2=0.30]

Glycine exists as H_3N^(+)CH_(2)COO^(-) while anthra-nilic acid, p-NH_2-C_6H_4COOH does not exist as dipolar ion.
