Synthetic gut is in essence a single-core premium nylon, compared to multifilament strings that consist of many superthin microfibers (nylon, polyamide, elastyl, polyester etc.), usually impregnated with polyurethane or nylon, and coated with silicone to reduce friction.
The later much better resemble (some of) playing characteristics of natural gut.
