WebGlycoproteins have a range of functions and are used in the recognition of different cell types by cells. Cell signalling also involves glycoproteins whereby they act as receptors or binding sites for hormones or drugs. This may be used to trigger a secondary response within the cell. Additionally, glycoproteins are also used for cell adhesion. WebHormones derived from amino acids include amines, peptides, and proteins. Those derived from lipids include steroids (Figure 1). These chemical groups affect a hormone’s distribution, the type of receptors it …
