From left to right, the above are general structures of β-lactam, a γ-lactam, a δ-lactam, and ε-lactam. Their common names are β-propiolactam, γ-butyrolactam, δ-valerolactam, and ε-caprolactam. A lactam is a cyclic amide, formally derived from an amino alkanoic acid through cyclization reactions.

These glands occur on leaf parts modified as insect-trapping structures. In the sundews ( Drosera ) the traps bear stalked glands, called tentacles. When an insect lights on the leaf, the tentacles bend down and cover the victim with a mucilaginous secretion, the enzymes of which digest the insect. See insectivorous plants.
