What is IgC described as in the immune response?

In the immune response, the secondary phase is dominated by immunoglobulin G (IgG). After the first exposure, memory B cells are primed to respond quickly, producing large amounts of high-affinity IgG when the pathogen is encountered again. This is why IgG levels rise prominently during acute and convalescent phases. IgG provides long-term protection and can neutralize pathogens effectively, unlike the primary response where IgM appears first and IgG rises later with lower initial levels. Antibodies are proteins, not lipids or carbohydrates, so describing IgG as a lipid or carbohydrate would be incorrect. The statement reflects the hallmark of the secondary response: a robust IgG-dominated antibody surge.
