Definition of cutin in English: cutinnoun ˈkjuːtɪnˈkyo͞otn mass nounBiochemistry A waxy water-repellent substance in the cuticle of plants, consisting of highly polymerized esters of fatty acids. Example sentencesExamples - Cell walls resistant to acid digestion were considered to contain cutin.
- The outside layer, or bloom, consists of wax plates and cutin, both of which resist water diffusion and hence water loss from the berry.
- The inner layer, being concealed against adhesive sampling, must be located within the mechanically resistant polymer matrix of cutin and can, hence, be interpreted as intracuticular wax.
- They oxidize diverse substrates such as membrane sterols, lignin, and cutin as well as hormones.
- The cuticle of terrestrial vascular plants and some bryophytes consists mainly of two hydrophobic components, the biopolymer cutin and a mixture of lipids, which are usually called ‘waxes’.
