Lutoid particles

A bottom layer consisting mainly of lutoid particles and also including other particulate components with a density greater than that of serum. Lutoid particles amount to 15 to 20% of latex volume. Their negatively charged tonoplast membrane, rich in phosphatidic acid, encloses a fluid serum known as B-serum. The vacuolar medium is acidic and positively charged. It includes cations, basic amino acids and a whole... 

Easily deformable gelatinous particles which comprise part of the yellow fraction of fresh natural rubber latex. Lutoids break down on the addition of ammonia and pass into the latex serum. 

NR latex is a suspension of NR particles with diameter from 0.05u to about 3.0 u in water. It also contains a smaller number of easily deformable bodies (lutoid), which consist essentially a viscous aqueous solution of non rubber particles, surrounded by a breakable membrane. NR latex which freshly- tapped from Hevea Brasiliensis containing about 367i dry rubber and 3V. non rubber materials (protein, fats, phospholipid, carbohydrate and nitrogen compound).
