$A$ is true and $R$ is false.

Vedclass · Answer

(C) Amino acids are organic compounds containing an amino group $(-NH_2)$ and an acidic carboxyl group $(-COOH)$ attached to the same carbon atom,known as the $\alpha$-carbon.They are substituted methanes where the four substituent groups occupying the four valency positions are a hydrogen atom,a carboxyl group,an amino group,and a variable group designated as the $R$ group.Based on the nature of the $R$ group,there are many amino acids (e.g.,glycine,alanine,serine).Therefore,the properties and types of amino acids vary specifically because of the nature of the $R$ group,not because the rest of the chemical structure differs.Thus,statement $A$ is true,but statement $R$ is false because the basic backbone (amino,carboxyl,and hydrogen on the $\alpha$-carbon) remains the same for all amino acids.

$(b)$ Immunoglobulin	$(ii)$ Immunity
$(c)$ Melanin	$(iii)$ Pigmentation of the body
$(d)$ Hemoglobin	$(iv)$ Muscle movement

$A$: The properties and types of amino acids vary.
$R$: The chemical structure of amino acids differs due to the $R$ group.
