<unk> s are one of many toxic constituents of many raw plants, which are inactivated by proper processing and preparation (e.g., cooking with heat, fermentation). For example, raw kidney beans naturally contain toxic levels of<unk>  (e.g. phytohaemagglutinin). Adverse effects may include nutritional deficiencies, and immune (allergic) reactions. Hemagglutination<unk> s are considered a major family of protein antinutrients, which are specific sugar-binding proteins exhibiting reversible carbohydrate-binding activities.<unk> s are similar to antibodies in their ability to agglutinate red blood cells. Many legume seeds have been proven to contain high<unk>  activity, termed hemagglutination. Soybean is the most important grain legume crop in this category. Its seeds contain high activity of soybean<unk> s (soybean agglutinin or SBA).
