Other claims from this paper (6)
- Observation Jojoba seed wax concentration varied from 49.2 to 55.1% across sites and years.
- Association The decrease in long-chain esters was associated with a decrease in C22 and C24 fatty acids and alcohols in jojoba wax.
- Association High temperature lowered the specificity of jojoba acyl-CoA elongation for C20-C22 and C22-C24.
- Association High temperature increased the specificity of jojoba reduction of the C20 acid to its corresponding alcohol.
- Observation The amount of C42 wax ester in jojoba was greater than expected by random association of the alkoxy-acyl groups.
- Association The preference for C42 wax ester over random association was not as great at high temperatures.
