Claims
- 1. A method for inhibiting phorbol dibutyrate binding to phorboid receptors of a mammalian cell comprising contacting under receptor binding conditions a mammalian cell having a phorboid receptor with a lipid-containing composition consisting essentially, as its lipid content, of a substantially pure lipid, said lipid characterized by having phorbol receptor binding activity, by having the ability to compete with phorbol dibutyrate for the phorbol dibutyrate membrane receptor, and by being an unsaturated diglyceride having a higher unsaturated fatty acid of 18 carbon atoms at position 1 and a lower fatty acid of 4 carbon atoms at position 2.
- 2. A method according to claim 1, wherein said lipid is isolated from milk.
